Hello All,

To all of those new to SIGLENT, welcome. Thank you for your interest.

The EEVBlog is a tremendous resource and idea exchange full of people that want to help. But, if you can't find what you are looking for OR have an issue with a specific product, I recommend writing INFO@SIGLENT.COM and include as much detail as you can. Other than a phone call, this is the fastest way to get a response from the factory.

In an effort to organize our info, we've updated this first post to include a summary of all of the main SIGLENT Specific threads currently running on EEVBlog:

Are you the Original Equipment Manufacturer of Owon?

please stop that, you just posted so much crap and advertisement for your crap ebay shops (Trade_Spotting_Shop and profit_vanity) , really, nobody wish to buy anything from your shop. Nobody cares about the crap you selling, so please NO!

Btw, if you would know a little about business or what so ever then:
- you would know that if someone is OEM for someone else, an technical support would never ever said that in public
  (unless allowed by management and already known, but then such post is pointless anyway)

- you would know that Owon is based, since 2008, on FPGA+ARM SoC and Siglent since 2009 on FPGA +DSP.
  Nobody ever would drive two platforms. Not even for firmware development. Not even 20yrs ago, and for sure not today

- if Siglent where Owon OEM, why they would then not use the knowledge and improve (actually both need it somehow)
  their platforms?

I am a technical support engineer from Siglent, and so glad to offer effective technical support

I do have question for you: by comparing latest models with and without "long memory" i recognized that
these without long memory are using only 4 (dual) ADCs instead of 5 (dual) ADCs as on long-memory enabled models.

I know how both works, and know that both ways have pros and cons:

4ADC + less interleave distortion due better ratio of clock jitter on non-dedicated FPGA clockout pins
                       vs. phase shit needs for 1GSs and amount of ADCs.
                    - higher gain distortion due overclocked ADC (125MHz instead of 100MHz on each channel)
                    + costs (one less chip)


5ADC - more interleave distortion due worse ratio of clock jitter on non-dedicated FPGA clockout pins
                       vs. phase shit needs for 1GSs and amount of ADCs.
                    + lower gain distortion due overclocked ADC (125MHz instead of 100MHz on each channel)
                    - costs (extra chip needed)

My question is actually why both ways? I mean if 5ADCs solution was working for years the change to 4ADCs can be
only price driven, no problem here to understand it, but when that's the way why only (i found it on 200MHz model,
so not the cheapest one) models without long memory are using 4ADCs?

Or maybe my pictures from models with long memory (here CA_M_110300 / SAT7.820.681K) are simply outdated ?
and Siglent is using everywhere 4ADCs (like on the pictures of CA_M_111000 / SAT7.820.681O with no long memory).

Well, that answer is completely useless, since anybody with half a brain can figure that out.

    I want to ask you something about the Siglent windows drivers... I have a Siglent SDG1020 AWG and a Siglent SDS1072CML oscilloscope, both with the same problem... The driver on the CD has a different hardware ID than the actual hardware ID of the equipment... And of course, because of this, Windows won't install those drivers... And even if I change the hardare IDs in the .inf file, the software won't see the equipment...

    The scope and AWG works fine with the NI VISA drivers... but still the same problem... The Siglent software doesn't see anything connected on the USB...

The operating system of your computer is win7 64bit?
You may need install the version  5.1.2 of NIVISA.

Siglent SHS806,

Is TrendPlot feature available only for multimiter inputs or it does work on scope inputs as well?
Title: Re: Siglent Technical Support join in EEVblog
Post by: Siglent on June 24, 2013, 01:22:57 am
I don't think it is a good idea to post all problem in a in-line single multi page forum, as it would so difficult to locate a specific support issue, especially when you may have 2 concurrent issues overlapping.

I would like to call upon Dave to consider opening an other forum section for manufacturer support topics and child forums for each manufacture, then each problem can be search individually, hopefully without doubling up of same or similar issues.

1.long menmory
With and without "long memory" are all used 5ADCs, difference is whether there is memory chips.
There are tow series, SDS1000CML (with long memory) and SDS1000CNL (whitout long memory)

2.ADC
All the products did not use 4ADCs

3.200MHz model
It is used in other solution, with only one chip (2Gsa/s)

This picture is from Atten product.

I think it is better that Atten answer Atten product questions.

OEM/ODM manufacturer is responsible to original deal partner and not third parties.

If I buy my product XYZD from OEM/ODM manufacturer, say example from Siglent, The first paper to be signed is a Non-Disclosure Agreement. Only then will begin negotiations with details. If then my  ODM manufacturer of a product, for example, would give any other information about it to third parties than I do, end up with the court.

"Yes we are OEM/ODM for this Atten product. All other questions you can ask from Atten"
I will recommend this answer.
Title: Re: Siglent Technical Support join in EEVblog
Post by: tinhead on June 26, 2013, 06:48:43 am
it does not matter what name on the product Case, the board has been developed (firmware and hardware) and produced by Siglent, so not Bongo Bongo or Atten or LeCroy have to answer "WHY they produced like that and if that was working WHY the others are not in that way" but Siglent as only Siglent need to know what's about.

EDIT: imagine someone got replacement mainboard, with hardware rev. CA_M_111000 / SAT7.820.681O and Siglent name on it. Whom have such person to ask "why here is no chip soldered" or "can i use it for X or Y model" or what so ever questions?

It is probably like what you said in the first page. Done. Question answered.

the real reason of my technical question was to check the quality of support.

If support person don't know what to answer, which was here the case as only product manager or the affected engineer can know why 4 and not 5 ADCs, the question need to be forwarded to someone who knows what to answer. It have to be completly forwarded, in its  original wording and not translated or with changed wording (or even worse, transalted and then forwarded with own wording).

Siglent can now compare my question with all the answer i got and think a bit about improvements to their support.

I really don't mind, actually happy to see Siglent support here, but when you do this guys, do it properly.

Hello!

Today I was measuring things with my Siglent 1072CML scope (7 months old, latest firmware), and after accidentally pushing the Horizontal Timebase knob, and so entering Delayed Mode at a fairly slow timebase, the scope froze completely. Complete lockup. Even restarting didn't help, the logo shows, the buttons light up all right, and then the unused buttons' lights go off as they should, but the screen still shows the logo and nothing else. Buttons don't respond, I tried every button, including Default Setup of course.

Do you have some kind of a method for clearing the unit's memory? It seems I pushed the scope into some kind of an endless loop. It seems, the Delayed Timebase doesn't work with very slow timebases, but the scope remembers the timebase and mode I was in. How can I reset the scope without returning it to the warranty service? Thanks,

Andor

Post by: andor on July 11, 2013, 01:07:07 pm
PS. I managed to connect the scope via USB and EasyScopeX, and I can send the *RST command. It successfully turns off channel 2, I hear a click from the scope. But that doesn't make the scope function.
Title: Re: Siglent Technical Support join in EEVblog
Post by: andor on July 11, 2013, 01:35:36 pm
Another PS:
By using the LeCroy WaveAce programmer's manual, I figured a way to remote-control the scope. I reset the scope, then started an auto-calibration, then saved the status into memory slots 0 and 1, and this seemed to help. The commands:

*RST
*CAL?
*SAV 0
*SAV 1

This firmware is about half a year old. Please update it, we could use some extra functionality.

And if Siglent really reads this: an idea. A great firmware feature would be to offer intensity-graded display, as on more expensive scopes. Those scopes perform >50000 waveforms per second. This scope only <=2000 wf/s. But if I had an option to see the actually captured waveform, while the DSP/FPGA calculates a statistical intensity-graded waveform based on the last 50000 waveforms... It would be great.

You wouldn't even need much of a memory for that. You could simply add a value saying "okay, I want statistics based on X waveforms". Then, each new captured waveform would count as 1/X in the statistical memory. Would it be possible to implement such a thing? Or at least, as a function of the EasyScopeX software? Thanks,

Andor

1. In order to guarantee the delay mode results, the function  be closed at the slow timebase;
2. When you rotate the timebase or voltbase, the unit's memory will be cleared

And if Siglent really reads this: an idea. A great firmware feature would be to offer intensity-graded display, as on more expensive scopes. Those scopes perform >50000 waveforms per second. This scope only <=2000 wf/s. But if I had an option to see the actually captured waveform, while the DSP/FPGA calculates a statistical intensity-graded waveform based on the last 50000 waveforms... It would be great.

You wouldn't even need much of a memory for that. You could simply add a value saying "okay, I want statistics based on X waveforms". Then, each new captured waveform would count as 1/X in the statistical memory. Would it be possible to implement such a thing? Or at least, as a function of the EasyScopeX software? Thanks,

Andor

Andor, thank you for your attention.
For your questions, make the following answers.
1.The *RSTcommand, restores the oscilloscope to its default settings:
 open the CH1, 1V/div, 500us/div, and close other functions
2.There is the *SAV command for the siglent oscilloscope , you can find the specific instructions in the SCPI manual.
3. The statistical intensity-graded waveform function will be achieved in the next generation of production

I recently started having a problem with the auto button of my SDS1102CML. When making measurements with the x10 setting of the probe it almost always expands the signal to fit the entire screen. But with the x1 setting of the probe most of the time it compresses the view (increases the time base and reduces the amplitude) so that you do not see any detail and have to adjust both the time base and the amplitude. Is there any particular reason for that?
P.S. This occurs mainly when visualizing the reference square wave of the scope. With an external signal there is no such problem.

Anomalies on Siglent SDS1102CNL
here are some screen shots
The first screenshot was acquired in NORMAL triggermode (trigger source C1,FALLING  EDGE)
The signals are the SDA and SCL signals on I2C bus and was generated manualy
There are 9 clocks on SCL(CH2) and the data transimted on SDA(CH1) was 00(8bit)
The second screenshot ilustrate the problem
After captureing the signals I pushed the FORCE button on the scope
Nothing has changed
Pushing again and again the buttun the result is the same, but after the fourth
push apears the second screenshot (CH2 cleared)
After the fifth push apears the third screenshot, wich is the right one  (both traces cleared)
After that I generated again the signals
Nothing happend
Generating again and again, after 27 times apears the fourth screenshot.
HORROR! I have expected to see both traces changed. But as you see only CH2 is
good and CH1 wich was the trigger did not changed.
After a new (28.) attempt both chanels are displayed correctlly (screenshot 1)
I repeated this a lots of times and there is no logic in the number of attempts
The minimum was 6 and the maximum was 70
Some times after a good aquisition You can push the FORCE button as many times you
want the traces won't disapear.
You have to change the trigger mode to AUTO and only then the scope became to work normally
My opinion is that there are two bugs.
1.)The screen refreshing procedure is wrong
Here is how can be:
If the scope is in NORMAL triggering mode after a good acquisition the software
will update the screen from the memory. That's ok. But if arrive a new trigger
than the software MUST NOT UPDATE the screen untill the memory will not be filled with the new data.
The second bug is the FORCE button.
If the user push this buttun than in that very moment the current acquisition must
be aborted and a new sequence of triggering must be initiated and the screen must
be blanked and no update generated untill a new acquisition is ready.
In this way can be eliminated the same problem wich is genereted in case of using
the C1:WF acquisition command when you want to download the data from the scope.
Now, with the current firmware, if you try to use this command in NORMAL or
SINGLESHOT triggering mode your program will freeze.
It works only in AUTO mode, wich is USELESS!!!!
I don't understand this limitation. For this limitation you can't use the LONGMEM
mode on Siglent CML series scopes in case of SINGLESHOT triggering.
Again: I don't see what kind of hardware limitation can be to don't use LONGMEM
mode in SINGLESHOT triggering mod on Siglent CML series.

Exept that it is not repaired in version 5.01.02.13
(yes it works as long as keep DC coupling selected.)
This happend example if there is default settings before Auto setup or least no one have changed coupling to AC. )

How it works:

A:
Input setting DC
probe and scope set for probe factor 1x
Connect probe to 1kHz probe compensation output.

Works perfect,
Base line move to vertical center(if not there before), CH1 change to 1V/div and horizontal speed 250us/div 

B:
Input setting AC
probe and scope set for probe factor 1x
Connect probe to 1kHz probe compensation output.

Autoset give poor result (fail)

Base line move to vertical center(if not there before) - this ok. Trigger level setting also ok, CH1 change to 2V/div (error) and horizontal speed 50ms/div (error), and signal is 1.5div high (-0.75 to +0.75div related to base line.)


C:
Input setting DC
probe and scope set for probe factor 10x
Connect probe to 1kHz probe compensation output.

Works perfect,
Base line move to vertical center(if not there before), CH1 change to 1V/div and horizontal speed 250us/div. Signal is 3div high, ( 0 to +3div related to base line)


D:
Input setting AC
probe and scope set for probe factor 10x
Connect probe to 1kHz probe compensation output.

Works perfect.
Base line move to vertical center(if not there before), CH1 change to 500mV/div and horizontal speed 250us/div.  Signal is 6 div high. (-3div to +3div related to baseline)

Result:
B fails, A,C and D ok.

Note. It looks like it is related to frequency. If I use external generator for 1kHz and 3V square also B ok. But only if frequency is enough different as scope own 1kHz. Scope own 1kHz is derived from scope clock.  If I use external 1kHz what is enough close scope own 1kHz result is same (fail) as with scope own 1kHz probe comp signal.  For more fun, result is same if I use external signal but adjusted enough close to what scope think is very close 10kHz and same with very close 100kHz.

Right, I missed that point, Auto (in 1x mode) works in DC and not in AC. I did not play enough with it.

I had only 2 different crystal oscillators to play with: 10 Mhz and 50 Mhz so I could only visualize their signal.

So this is a firmware issue not a hardware one, at least there is hope that they will fix it in the future versions.
Thanks rf-loop.

On this issue, because Auto algorithm 's sake, in dealing with AC and DC coupling process caused
, and in the next version of the Auto algorithms are optimized , and the default is DC coupled.

I have the same scope, and about a day after I bought it a few weeks back I saw a post somewhere basically saying they had reached the end of their life cycle and would get no more updates. I hope that's not right, because I have to say that after using mine (with the latest firmware) for a few weeks it is dicky as hell. They definitely need to take another stab at making these things work properly. Lockups, intermittent wildly incorrect measurements (the other day I noticed that from one stable source I got 3 different readings on 3 different vertical settings. I'm not talking millivolts either, I'm talking +/-25%, an obvious bug), quite a few bizarre bits of behaviour.

Please can you show data about signal used for test and  documents about this error, including oscilloscope model, FW and HW versions. Also document about scope settings and how test signal is conneted.  This is only way to try solve possible problems. 

I have used Tektronix oscilloscope calibrator (CG5011 and CG5010) and never seen this kind of amount of error, and I have tested every single scope what I heve sold.

End of life cycle?  SDS1000L serie. Not.

Even after new SDS2000 and possible SDS3000 serie SDS1000L do not go obsolete.

Just we have get  (perhaps first) series 5.xxxxxxx FW   after many 3.xxxxx FW's


Siglent have officially informed what models are end of life cycle and production stopped. (this information they give time ago and before production stopped) (support continue as example warranty services and spare parts etc)
 
Example SDS1102CM  (and other old 5.7" display old SDS1000 models.  This information is official and list and dates can read in Siglent official sides.

The SDSxxxxxxL series is DEFINITELY not obsolete. I believe they were released in 2013, and correct me if I'm wrong, replaced the 5.7" displays, which I believe was officially EOL'd on April 22, 2013. I just bought s SDS1102CNL because I needed a digital scope and my Tektronix 2465 that I got for my 9th birthday went pop. I'll probably try and fix it sometime.  :-BROKE

Phew, glad to hear that! I was a bit pissed off when I saw that post and thought this thing was going to be stuck with these bugs forever.

Yeah when I get time I'll try to sit down with it and document the problems I'm finding properly. So far it's just been a bunch of mid-job WTF moments that I just tried to fix and get back to work immediately rather than explore. The point of my post wasn't so much to get troubleshooting help, it was to point out that the current firmware is still far from perfect and on the (apparently wrong) information that there would be no further refinement that was worrying.

Yes but there is Youku.

I have inspected more than just one SDG1000 series and one SDG5000 series. No corrosion/rust at all. Also some other members have looked inside SDG5000 they have and no rust/corrosion.

But, it can develop corrosion too easy, due to material and metal work (perhaps Siglent need give more tight instructions/commands to mechanical parts supplier)

This is not true serioius problem in normal envinronment where these machines are typically used.

But this may happend example after metal case have made and then restored perhaps in very humid or better say wet place before they come inside Siglent factory.  Shenzhen area is very humid and wet many times. Sometimes some cartons may be wet and they stay somewhere outside wet, humid and warm place... I have seen this in china industrial area many many times.

So this quality control need cover also whole production chains, also these sub manufacturers who do some parts of equipment.

Perhaps it is good if Siglent more carefully design also materials what are used for these parts.  And also more tight control when they receive these parts from suppliers. If not meet quality, just return back and tell to supplier that this lot we do not accept. Money is good teacher.

Hi. Since this waveform generator I have observed this problem.
with a 10 MHz external time base works perfect, but with its internal time base shows a difference in frequency.

that may be the problem and how to fix it?

I contacted by mail with siglent, but apparently you have to recalibrate all equipment by service software. but it seems strange since it is assumed that the instructions should be correct calibration

there is a simpler method?

not see any setting to recalibrate the internal reference oscillator.

Your freq counter is not connected to accurate external standard? 

This error what it now show is far out of specs (+/- 100ppm class so error with 10MHz can be +/-1kHz but no more)
.
IF freq counter have no freq error.
What is true error?



There is no freq adjustment for internal oscillator. It is specified for its initial and long term accuracy.
If need  more accuracy, it need use external accurate reference.

If with some undefined reason internal  ref oscillator is out of specification it can of course change.


Inside SDG1000 there is also place for better reference but it need (afaik) also modified FW from Siglent.

The frequency counter has the correct internal oscillator. I have tried other counters and the result is the same, the smaller image corresponds to screenshot of my DSO shows the same error rate  :palm:

Latest firmware is nothing to do this what I told.

I told, there is place for better freq reference (OCXO). There is allready place for it on the board but it need special FW also what support it. (Time ago Siglent tell me this)
If want install this special option it need instructions from Siglent how to do.


But if just change original default oscillator (and this is now case) to new one it can of course do.

I believe it is now out of limits but your method do not proof it. You have measured it by undefined accuracy. If one DSO have around what also your counter, it do not really proof so much.

For real proof if siglent is out of specs or not and how much it is out of specs you need least +-10ppm true trusted abs accuracy or far better. (oh well it is easy get and perhaps your counter is inside this but this can not be sure with this information what is now.

If it really after trusted measurments is >400ppm off, it is absolutely too much = fail.

If there is warranty, contact first seller what to do.

If seller is just only carton shipper then contact Siglent and ask help for get this back to normal working state.

Thank you very much for your reply and clarification.

I apologize if if at some point some of my words are bad interpreted, it is because this is not my native language and I not have a good command.

Actually I know the fact of user firmware does not alter the technical parameters of the system. SIGLENT provided me a procedure and calibration software. but I see too complicated for just this problem. I also assume that the parameters listed in this procedure are those that were loaded at the factory

I have all the data and software needed for calibration, but I dare not publish it without prior approval from SIGLENT.

I tend to think it's more of a hardware problem in the internal 10 MHz reference may be interesting as you indicate replace the internal oscillator.

Siglent fixed that "Auto" button problem. I got the new firmware and it works. However if the scope is in AC coupling mode before pressing the "Auto" button, it switches back to DC coupling therefore shifting the signal (with a DC bias) after rescaling it on the screen.

More problems with SIGLENT SDS1102CML
If you get the Sampling Rate with the command SAMPLE_RATE? you'll get the right one no matter if LONGMEM is selected or not. But if you read the Sampling Rate from address 176 in the WAVDESC than in the case of LONGMEM on you'll get the half of it.
Example:TimeBase is set to 100nS and LONGMEM is on.
If you press the ACQUIRE button you can read 500.0MSa on the scope. That mean 2ns sampling time
Now if you get the trace with the command C1:WF? and read the Sampling Time in the WAVEDESC at offset 176 acordingly to the specification of SDS1000_REMOTE_CONTROL_MANUAL_1.2 you will read 4ns
There are a lot of more bugs. I am wondering why Siglent newer answer to my remarks.
But the most annoying problem is that I can't get all the 1mega data using the Command C1:WF?
I know that with easyscope program you have an option to select LONGMEM, download the data, and save it in .DAV format. unfortunately on my scope the EASYSCOPE dosen't work. I'd like to know if somebody who have a SIGLENT SDS1102CML had ever succeeded to get all the LONGMEM data.
An other problem is the STORE command.
The syntax is: STORE [<trace>, <dest>].
The <dest> parameter can be an USB stick UDSK.
As <trace> parameter you can select a channel or ALL_DISPLAYED
BUT THE MOST IMPORTANT wich is ALL that can't be!!!!!!!!!
I mean ALL as ALL THE CHANNELS.

I have updated the firmware of my ATTEN ADS1102CAL with the SIGLENT SDA1102CNL firmware (SDS1000CNL_SSP_V100R005B01D02P13)
Now in the System Status menu I have:
Software version 5.01.02.13
Harware Version  10-61-3.3
Product Type     SDS1102CNL
The serial nuber is the old ADSxxxxxxxxxx

Everything works normaly BUT !!!!!!
I can't find a proper USB driver for USBMTC device
Before the upgrade the EASYSCOPE 3 program has found my scope using the UOWORD.SYS driver
Now the program can't find the scope


You have purchased Atten oscilloscope.

Then you have modified it with Siglent FW (CNL model)

Then you perhaps have added some kind of memory(?) and changed FW for Siglent SDS1102CML.
Or do you now have genuine Siglent product. 

Who knows after these all modifications how it works or not?

If want Siglent product, it is also better to buy Siglent product.

You have Atten product but where is ATTEN support now.
(btw, why you modify it using Siglent FW, why not Atten FW.)

Title: Re: Siglent Technical Support join in EEVblog
Post by: illyesgeza on August 04, 2013, 08:15:21 am
on a SDS1102CNL you can not!!!!
on a SDS1102CML I think it will work (99.99%)
but I did not tried. What I realy don't know if the buttons are at same ports.
If you try the Lecroy WaveStudio program, you will notice that all the buttons can be manipulated by remote commands, but their positions on the screen are not correct.

Siglent fixed that "Auto" button problem. I got the new firmware and it works. However if the scope is in AC coupling mode before pressing the "Auto" button, it switches back to DC coupling therefore shifting the signal (with a DC bias) after rescaling it on the screen. May be it's just me being picky. How do other scopes behave (if they do have "Auto" type function of course)?

In the new version, made the following modifications:
AUTO perfect algorithm to enhance the speed of response, and unified the DC coupling

This strings are inside my scope
siglent
ca_m_111000
sat7.820.6810
rz-02a
94v-0
e322892
and this is what I got in sytem utility:
Hardware version:  10-61-3.3
Software version: 5.01.02.13
Product type: SDS1102CML
You have asked me about other problems.
Yes there are a lots of.
Example:
If you use the command GCSV? DD,MAX,SAVE,ON
than the scope freeze. It must be powered off.
In case of GCSV DD,DIS,SAVE,ON everything is ok.
This problem have nothing to do with LONGMEM ON or OFF
In both cases the scope freeze.
If I use the SAVE button I can save the data acordingly to LONGMEM and DISPLAYED
ex: LONGMEM off, DataDepth Maximum -> filesize will be aprox 600Kilobytes
    LONGMEM on,  DataDepth Maximum -> filesize will be aprox 60Megabytes
    LONGMEM off, DataDepth Displayed -> filesize will be aprox 300Kilobytes
    LONGMEM on,  DataDepth Displayed -> filesize will be aprox 6.3Megabytes
So it is obvious there is a software problem wich is not related to the hardware.
I don't want to repeat me, but it would be great to solve the problem with the WaveForm realted commands
WFSU does not work
WF?   Does not work in LONGMEM ON mode.

Anomalies on Siglent SDS1102CML.
Here are some screenshots
The ETS bugs don't bother me.
BUT !!! the realtime problems YES!!! (SDS0003.JPG, SDS00004.JPG)
When you get the trace with C1:WF? command you got the wrong sampling rate
because in that moment the acquisition is stoped. Just like in this example
As I said in an earlier post you get the half of the sampling rate

Select both chanels. select LONGMEM. Select Trigger EDGE,SLOPE+,NORMAL,source CH1.
When you have a stable image make a screenshot.
Then push the STOP button and make an other screenshot.
I'd like to know if both traces remain in the same position as in RUN mode.
There is not the generator's error. In LONGMEM OFF mode everything is OK.

I'd like to ask SIGLENT why is possible to make an one shot acquisition on 20480 samples, and why not on 1mega samples.
If it's a realtime sampling mode, there must not be related to the number of samples. So simple.

Post by: illyesgeza on August 09, 2013, 09:41:03 am
Question for SIGLENT.
If the hardware can not make a continuous acquisition on 1 mega samples after a SINGLE!!! stable trigger, in that case there is no need for LONGMEM.
I can not figure out what kind of REALTIME  acquisition metod is used to have such a limitation.
This limitation is also on ATTEN and LECROY.

I've played around with the sample rate, and only have had 1 channel turned on. The same old 20k.

Under 1GSa/s normal memory is 20k for each channels independent if 1 or 2 channels in use.
1GSa/s normal memory is 40k. (1GSa/s available only if one channel in use and normal memory and timebase is 50ns/div or faster.

(In theory of operation, there is 2 x 500MHz ADC* and after both there is 20k sample buffer what can take full 500MSa/s.  When scope use 1GSa/s these two ADC are interleaved, and so also these two 20k sample are interleaved. In end when read this sampling buffers  alternately there is 1GSa/s data and 40k data points.

*made  using several interleaved 100MHz running ADC's)


Here CSV start with 1 channel in use and 1GSa/s (50ns/div)  and second is 1 channel in use and 500MSa/s (100ns/div)

CSV really have this amount of data points what it tell record lenght.

NOTE: In save menu there need select of course "Data Depth" = "Maximum"
(other selection is "Displayed")

And if want parameters "ParaSave" = On

Also if stop capture there is same 20k or 40k in sample buffer and visible.

Here start from both stored CSV
opened just normally with OpenOffice Calc (only mod is serial number hide)

It looks like it's from the same guy who also does atten.eu
No official Siglent factory website !
Indeed, both sites are operated by JR Special Electronics. KVK nr: 52793575 Rivierensingel 325 5704KN Helmond The Netherlands
They put alot of effort into pretending to be official manufacturer websites...  :--

Hi all,

Let make something clear  :)

Yes I do have multiple web-shops Like ATTEN.EU Siglent.eu and more.
These web-shops are run independently from the Chinese cooperation's BUT this doesn't mean we do not communicate.
The websites are made to have a better support and promotion in the EU with these products.
The assumption that we are non official is wrong. Siglent.eu is a official reseller like many other resellers.

I do not think it is very nice to make a assumption that we are pretending!
If you do not know how things are set up please do some research first.

Please feel free to contact me if you have any questions.

Greetings,

I have a Siglent SDS1102CM oscilloscope but it has suddenly stopped working and now only ever displays its splash screen - anyone else ever seen this?

When I turn on the scope the buttons light up as usual and the fan runs. The splash screen appears and the buttons lights go out (except measure, run/stop, CH1 and CH2 lights on) but that's as far as it gets - the splash screen just stays there and pressing the buttons doesn't do anything. The scope first entered this mode when I pressed the horizontal time scale zoom button.

Anybody (SIGLENT?) know of a back door way to force a 'restore to factory defaults'  - perhaps powering up with certain buttons pressed etc?

Chris.

[Edit] Just noted Andor's post from earlier in this thread where he reports the same thing. Andor, if you read this could you confirm that you managed to get your scope out of this lockup? And could you explain/confirm the steps I need to take. Cheers.

The same thing happened to mine 3 days after I purchased it. 1202CML...but mine wouldn't even bring up a splash screen. Power on would cause the fan to start spinning, but no other lights or anything on the screen. I sent it back because I could not figure out how to make it work again (and frankly, it shouldn't have broken that way)...

Well it seems there is indeed a back door mechanism to reload defaults - repeatedly press the math button whilst the scope is initialising does the trick nicely. Many thanks to Andor for helping me out with that :-+. Perhaps Siglent will consider publishing this trick in their manual as it would appear there is a 'persistent' lock-up bug lurking in the firmware waiting to bite - no big deal if you now how to clear it but very worrying if you don't!.

I will recommend that if we report some this kind of problem/bug etc things we also include model, FW and HW version information. Just becouse different versions are different.

Example earlier someone told freezing if push accidentally delayed  using very slow horizontal speeds and then scope freeze. Least in FW version 5.01.02.22 there read pop up message "Function is not useable" and nothing happends.

Fair enough, here are the details in my specific case:

Model:SDS1102CML
Hardware: 11-62-3.3
Firmware: 5.01.02.13
CH1 and CH2 enabled, 1V per division, x1 probe
Trigger: CH1 Falling Edge, Auto
USB stick present
Measure: on screen Time measurements display active.
Timebase: must have been around 10uS but I don't know the exact setting - certainly wasn't 'slow'

Pressing the timebase button caused the splash screen to appear. What ever 'setting' causes the error is remembered after power down because the scope re-enters the same state after its usual power up sequence.

Reloading factory defaults by rapidly pressing the MATH button whilst the scope is initializing fixed the problem.

The lockup is not easily repeatable - I've attempted to replicated it but have so far failed.

Yeah I saw that a while ago but I'm not sure about installing it without Siglent actually pushing it out. What's the deal with this version, is it actually finished or a pre-release beta or something? How did it get up there, from Siglent or a third party? If I install it before they officially have it on their site and something goes wrong am I covered under warranty or will I get a response like "We didn't actually release it on our site yet, too bad"?

New scopes from Siglent factory have  HW 5.01.02.22,  (least) in  SDS1102CNL and SDS1102CML models.  This I have seen with my own eyes and also tested these version scopes.

After then, I have asked from Siglent if I can get this new FW also for update units I have in stock with FW 5.01.02.13 and also for update my customers equipments if need.  After this, they send me FW5.01.02.22 update zip.  But, in this phase they know what are versions what I may update with it.  So, I do not have information if it is fully backward compatible with all FW and HW versions. So, becouse this, as long as I do not have more trusted information, I need give warning that I do not know if it is compatible or not.

 
I have test updated one SDS1072CML HW 11-62-3.3 with 5.01.02.22.  It looks like it works but without full tests of course - who can test all settings combinations - no one.
Then I tested if it can downgrade. It can. I have then "update" it back to 5.01.02.13 and it looks like it works.  So, it looks like bridge to run back is not broken. But, how about older and other versions - I really do not know and I do not k now if this is reason why there is not yet official downloadable.



With these updates need be careful becouse example old times when updates was not public there was situation that some very old version need first update to some more new version but not newest, and then update to newest. (this was information get directly from Siglent and for SDG1000). And with this kind of thing - Siglent is not alone.  Also example Owon, all HW versions are not compatible with all FW versions. And I suspect this situation is with many brands.

btw and fully off topic (of course as usual):


Some things, just  for playing and study with SDS. (http://siglent.freeforums.org/sds1000-series-files-to-usb-dav-csv-rgu-set-bmp-t79.html)

I too updated my SDS1072CML HW 11-62-3.3 SW 5.01.02.13 to 5.01.02.22 and the trigger status kept jumping between "Ready", "Armed", "Auto" while using auto trigger on slower timebases. Didn't like it at all so I've reverted to 5.01.02.13 but rf-loop told me there are some good changes and bugfixes, too.

I too updated my SDS1072CML HW 11-62-3.3 SW 5.01.02.13 to 5.01.02.22 and the trigger status kept jumping between "Ready", "Armed", "Auto" while using auto trigger on slower timebases. Didn't like it at all so I've reverted to 5.01.02.13 but rf-loop told me there are some good changes and bugfixes, too.

This "ready-armed-auto" sequence is "true" but flickering is not nice looking and also it now interfere with TFT update period.

Default scope.
Connect probe to 1kHz probe cal output.   Set scope horizontal to 50ms/div.
Set now trigger so that level is example under this signal level so it can not find trig. In this case it generate "auto" trig and  it can see when it slowly do this sequence "auto -> armed -> trigged"
Then move trigger level so that it is around middle of signal. Now you see it do not generate "auto" and  sequence is "armed -> trigged"
Keep trig level this. Change trigger to Normal. Still it show "armed -> trigged.... armed.. trig's ...."
Move trigger level to under signal level ... "...armed...ready and now it waits until it find trigger.
now of course it do not force trigger by auto. In auto mode it generate auto force for trigger in case it do not find trig.

With more fast speeds it can not update this in TFT and it looks like it blinks random. More fast times it do not blink if it finds trig there read steady Trig'd. But if fast speeds move trigger level so that there is not trig its start blink becouse this autotrig is more slow. First it need find that oh...there is not trig... lets force trig (and in this case of course it is out of sync with signal)
Very fast speeds if not find trig (move trig level out from signal) , only there read "auto" and it trigs with auto period  and tell to user that trigger is not from signal, it come from auto process. Then if change trigger level so that it find continuous steady trig enough fast it do not start auto trig process and there reads steady "Trig'd". 


Idea is right and  good but solution need some fine adjustments for this indicator  timing so that it do not "random blink" when speed is so that it can not update to tft and right for human eye so that it display Ready, Armed, Trigged and Auto just as it give best information to user, but then depending of settings and horz speeds and signal itself timing need be so that it do not "blinking randomly" becouse indicator can not update, then need think what tell to user best useful information about current working status related to trigger.

Hmm, thank you for the detailed description, rf-loop. I perceived it as an obvious bug before but now you've convinced me they've actually tried to make it more informative and let you know the exact moment the auto trig is enforced. But I too think it's still not exactly optimal way to do that. When something is apparently randomly flickering at you, "something's not right" is your first and natural reaction. Also, if you're capturing screenshots, you'll have random things in the trig status field. Now, maybe they should do away with the trig status in the text form and substitute it with a row of individually "dimmed/lit-up" symbols, like: "[A][T][Au]" (too bad that "Armed" and "Auto" both start with an "A" ;)).

At last, after I flashed the new SIGLENT SDS1102CML FW: 5.01.02.22 on my dso, I succeeded to download all the 1048576 bytes of data on both channels.
The correct syntax to do this: STOP;C1:WF? that's how get channel 1
After that: C2:WF?;RUN for the second channel.
The STOP and RUN are the main issue here.
This is not documented neither by SIGLENT nor by LECROY
If you use *TRG before WF? you'l get only the short mem data because the FW switch temporarily to NORMAL MEM mode

Although both have the word "official", do you understand the difference between "official manufacturer" vs " official reseller/distributor" ?

Just because someone own the domain name "siglent.xxx", doesn't mean automatically they are the "official manufacturer", am I right ? Again, I'm talking manufacturer, "NOT" reseller nor distributor.

Hi,

I'm new to this forum (and somewhat new to electronics, for that matter).  It's nice to see Siglent here on the forum.  I've been looking at the SDS1102CML and the Rigol DS1102E.  I have no urgent need for an oscilloscope at this point but I think I could learn a lot by having one.  I really like the larger screen, better pixel resolution and larger memory size of the Siglent.  However, the lock-up issues and apparent delays in publishing firmware updates have me a little nervous about the SDS1102CML.

How committed is Siglent to supporting (and updating firmware) these oscilloscopes in the long term?  Will SDS1102CML firmware revisions continue even if Siglent introduces a new line of DSO's in the near future?

I'm really afraid of buying one, owning it for some time then developing a problem, only to find out that support is discontinued.  I know the price of these devices is low compared to other brands and types of oscilloscopes, but $400 doesn't come easy for hobby pursuits in my household.  Regardless, nobody wants a $400 paperweight on their workbench, right? 

So, what can anyone tell me that will alleviate my concerns about these Siglent 'scopes?  I'm a hobbyist and won't be pushing these things anywhere near their design limits, but if I spend the money on a 'scope, I want it to work reliably.

Thanks in advance for any responses.

BeerCannon, don't fall into the logic trap I once found myself in by assuming that if it has programmable logic in it, the manufacturer has to provide you with the firmware updates on a regular basis by some moral obligation. You don't expect this from your microwave manufacturer after all. There's nothing I'm aware of that is seriously wrong with the Siglent SDS1000 series and it basically does what is says on the box. And the firmware won't suddenly go bad on you overnight. Personally I haven't experienced the lock-up issue but it's great to know that the guys here figured out the way around it. From what I know (someone please correct me if I'm wrong), Rigol doesn't post any firmware updates on their website at all - you have to ask them explicitly. I'm pretty sure that both Rigol's and Siglent's entry level products are great at what they are meant for. If you're worried about it becoming obsolete and unsupported, the Siglent SDS1000CML's are much more recent products than Rigol DS1102E. Anyway, pretty much every piece of equipment you buy is more or less "obsolete" at the very time you buy it and there's not much we could do about it other than learning to cope with it ;)

EDIT:
As for the delay in publishing the *.22 FW update by Siglent, I tried this version and wasn't exactly happy with it - that's why I assume they'll just skip it and publish the one they feel is solid enough.

ZBig,

Thanks for the vote of confidence for the Siglent scope.  I don't expect a stream of firmware updates if the unit is working properly at the current revision.   I also don't expect to turn it on one day and find that it won't boot (unless there's a hardware failure of some sort).  If the firmware is solid, I don't care if they ever update it.  But if there's a known issue, I'd rather buy from a company that will fix it instead of moving on to the next product line without correcting the existing product.  It sounds like Siglent is striving to be such a company.

I was really impressed with the unboxing/overview of the SDS1102CML in the video by ToolBoom.  I also realize that when you look online for criticism of a product, you mostly find the negative experiences, which may be few and far between in the real world.   That's why I figured I'd ask around in a forum such as this one, where I can get some balance.   I also talked to Al at Saelig.com and he had good things to say about the Siglent (as well as the Rigol). 

Thanks again for weighing in.. my anxiety about a potential 'scope purchase is beginning to subside!

"Depth Recover" will remove the stored waveform, setup and  the mask setting of Pass/Fail function.

Hello!

I am trying to measure Source-Drain voltage drop in switching DC-DC converter with Siglent SDS1072CML:
(http://img.radiokot.ru/files/47221/thumbnail/7cj3n3hot.png) (http://img.radiokot.ru/files/47221/7cj3n3hot.png)

Source-Gate voltage drops down to -13V to open MOSFET fully:
(http://img.radiokot.ru/files/47221/thumbnail/7cj7hg357.png) (http://img.radiokot.ru/files/47221/medium/7cj7hg357.png)

I have a 750mA load connected.
Peak current across Drain-Source is about 1A ( measured on Rx resistor):
(http://img.radiokot.ru/files/47221/thumbnail/7cj8dz270.png) (http://img.radiokot.ru/files/47221/medium/7cj8dz270.png)
(http://img.radiokot.ru/files/47221/thumbnail/7cj9r4y4t.png) (http://img.radiokot.ru/files/47221/medium/7cj9r4y4t.png)

The Drain-source image looks like this:
(http://img.radiokot.ru/files/47221/thumbnail/7cjbk8v75.png) (http://img.radiokot.ru/files/47221/medium/7cjbk8v75.png)

The voltage drop across open MOSFET is 900mV!  The accuracy of oscilloscope is 0.2 * V/div, so there is +-100mV error range.

According to datasheet, voltage drop can not be more then 500mV:
(http://img.radiokot.ru/files/47221/thumbnail/7cjf22sz1.png) (http://img.radiokot.ru/files/47221/medium/7cjf22sz1.png)

And if calculated from RdsOn=0 .14Ohm, it should be about 140mV, which is far from 900mV displayed.

The strange behaviour of oscilloscope is that increasing V/div drifts Vmax and it eventually goes above zero to 1V with 10V/div!
I can accept it with 10V/div because error is 0.2 * V/div = 0.2*10 = 2V, but with 500 mV/div readings should be close to reality, otherwise it is impossible to find out whether I am correctly driving MOSFET.

I have latest firmware. I've been trying switching probe ( and oscilloscope settings ) to 1x/10x without improvement.

I took my old USB oscilloscope from the shelf, and it shows Drain-Source voltage drop <300mV and does not have that strange zero drift with V/div encrease:

(http://img.radiokot.ru/files/47221/thumbnail/7ga8etzgb.gif) (http://img.radiokot.ru/files/47221/medium/7ga8etzgb.gif)

How could I correctly measure Drain-Source drop with my Siglent?

Unfortunatelly it does no work.

With 500mV/div I am able to set offset voltage to -36V and see voltage on source( CH2, blue) and on drain (CH1, yellow).

Drain voltage appears to be higher when source which is impossible:
(http://img.radiokot.ru/files/47221/thumbnail/7h94pe0s8.png) (http://img.radiokot.ru/files/47221/7h94pe0s8.png)

(http://img.radiokot.ru/files/47221/thumbnail/7h94apoxn.png) (http://img.radiokot.ru/files/47221/7h94apoxn.png)

With 200mV/div maximum offset voltage is 1.6V so I can not use it.

Post by: tautech on December 08, 2013, 08:03:17 pm
No offset required, use AC coupling, same reference(0V) both channels(only 1 needed) and 1 probe on source, 1 probe on drain.
Then use minus to show the difference between channels.

4ADC + less interleave distortion due better ratio of clock jitter on non-dedicated FPGA clockout pins
                       vs. phase shit needs for 1GSs and amount of ADCs.

5ADC - more interleave distortion due worse ratio of clock jitter on non-dedicated FPGA clockout pins
                       vs. phase shit needs for 1GSs and amount of ADCs.

Ah, _shift_.  :)

Probably that's the problem. You overdrive the input amplifier

You do not need offset.
Use AC coupling in each probe menu.

1) I think I can use +-40V offset on 500mV range:
(http://img.radiokot.ru/files/47221/thumbnail/7hxumg9zb.png) (http://img.radiokot.ru/files/47221/7hxumg9zb.png)

2) I do not think I can use AC couping. With AC coupling channels have different offset voltage:
(http://img.radiokot.ru/files/47221/thumbnail/7hxyklesq.png) (http://img.radiokot.ru/files/47221/7hxyklesq.png)

And math does not account for it. It substracts what is seen on screen, and it does not give me any usefull information:
(http://img.radiokot.ru/files/47221/thumbnail/7hxuvtl5o.png) (http://img.radiokot.ru/files/47221/7hxuvtl5o.png)

Also original question is still actual. While specified accuracy is:
(http://img.radiokot.ru/files/47221/thumbnail/7hy538t2u.png) (http://img.radiokot.ru/files/47221/7hy538t2u.png)

For offset=0,
500mV/div:
expected reading=140mV:

0.03*140 + 500*0.2 + 0.01*0 + 0.2*500 + 100 = +-304mV

and I see 900mV instead of expected 140mV +- 300mV.

(BTW now I realize that 0.2*V/div+100mV error is too high to sense 140mV even with 206mV/div).

I am affraid the only way to sense Source-Drain drop with 140mV - 36V swing is to use 1V resistor+zener to limit swing to 140mV - 1V. Then I will be able to sense at 100mV/div range.

Currently picture on 100mV/div looks like this ( DC Coupling):

Ok, so I soldered 1n4148 and 1K resistor to limit forward voltage to ~0.7V:
(http://img.radiokot.ru/files/47221/thumbnail/7ibsbytek.png) (http://img.radiokot.ru/files/47221/medium/7ibsbytek.png)

and was able to measure voltage drop on MOSFET at 200,100,50 and 20mV/div:

(http://img.radiokot.ru/files/47221/thumbnail/7ibyj9247.png) (http://img.radiokot.ru/files/47221/medium/7ibyj9247.png)

It appears to be ~80mV which is very good.

So there is a practical way to measure voltages with large  swing. It is important to use diode with low capacitance.

But I am little dissapponted with oscilloscope accuracy which does not follow specification and appears to be lower then my old USB oscilloscope.

Hi,

I recently purchased SDS1102CNL.  With the 1x scope probe attached to the build in 1khz reference signal, vertical setting at 200mV/div, the square wave looks distorted.  Turn the knob to 500mV/div, the square wave went back to normal.  The software version is 5.01.02.13 and the hardware version is 11-62-3.5

Is there a setting?  Firmware update?  Or the unit is possibly defective?

You have the latest Firmware.  :)
It is normal for these entry level scopes to wrongly display the Calibration waveform with the wrong input settings. Many scopes wrongly display any waveform that as largely OFF the display.
Set correctly for 1 KHz and 3 V pp (1V/div) all will be OK.

Get into the habit of using ONLY 10x probe and scope settings and only use 1x when you need to.

Valid voltage range for 200mV/div is +-1.6V.

Reference is 0...3V.

Unfortunatelly all signals above range are displayed distorted, and no warnings are given.

Sorry, but my Owan SDS7102E  is Just the opposite.
With the 1x scope probe attached to the build in 1khz, 5Vpp reference signal, vertical setting at           100mV/div, the wave should not be dispalyed full scale. howerver, it is good but valid when adjusting   the vertical position.
While with 10x scope probe, it seems like what Siglent SDS1102CNL shows.

The point I have tried to make is by using a 10x probe and scope settings there is a lesser chance of an unusual off-screen waveform and your scope is more protected from unknown (high) voltages especially the many with only 300V pp inputs.

As many will know this was to be avoided at great length with analogue CRT scopes to prevent damage to the vertical plate deflection amplifiers.

I would've think my scope is normal if it displays the waveform like Ferrari's, but I don't.  In fact, rather than clipped waveform, I see a gradual ramp-up at 1x which is puzzling.  Switching to 10x, I see similar to Ferrari's (due to uncompensated scope probe).

For now, I will use 10x unless Siglent is providing a solution, but I take it that this is typical of low cost scope?  :-\

I just purchased a siglent SHS810 and I am regretting it worse than that hantek DSO purchase I made earlier. The multimeter section of the siglent is totally screwed up out the box. The scope portion is working but the meter section is locked up. In meter mode the value of 1.0 is locked on the screen, no i do not have the unit in stop mode. The unit is stuck in manual configuration on the measurements and continuity checker is constantly latched. I can not take a single measurement because the whole multimeter is locked. I upgraded the firmware and it has the same issue. When I can manage to scroll to DC current measurement the number 1 keeps randomly flashing.

My Faulty Siglent SHS810
SHS810 FAULT (https://www.youtube.com/watch?v=6xEIzrDANNQ#)

Russian Guy Faulty ShS806
shs806 (https://www.youtube.com/watch?v=oiV0B4YUS4Y#ws)


Update

After a back and forth with a stumped Siglent technical support who encouraged me to disassemble the unit for the record and reseat the multimeter module which did not solve the fault,  the real solution for my problem came from a third party on how to fix the scope.  The problem I was having with the Shs810 was not isolated to my scope or even the model.  Another user from Russia with a Shs806 discovered that the crystal clocking the multimeter module on his scope had a cold solder joint. Examined my shs810 and discovered the same thing. I retouched the joints and the shs810 has not acted up since.


During my closing emails from SIGLENT China the best they would do for me is replace my shs810 100mhz scope with a shs806 60mhz scope because they had no available shs810, now does that make any sense. The Siglent tec tried to convince me that going from a 100mhz band to a 60mhz band after I freckin paid for the 100mhz band is not a down grade and no I was not offered back the difference in price.

Bottom line is Siglent as a company did not solve the problem, a problem that was a result of their manufacturing. As a result of horrible customer service I will never buy from Siglent again. If you buy Siglent make sure you can return it to the seller if it goes bad on you and pray that if it does go bad it does so in the return window because beyond that you are at the mercy of Siglent warranty and their mentality with me with a product I bought defective out the box was "you got a bad brand new unit fix it your damn self" which is what happened

Also be warned of the re branded version of this product line being made for BK Precision.  Models 2511, 2512, 2515 and 2516. Your only hope here is if things go bad within the warranty period since it is a BK branded product than BK will actually honor the warranty.

If you just use sine output,you can't  get a 30 MHz sine,but you can use the arbitrary function to output 30MHz sine.
The highest frequency of arbitrary wave is 5MHz, use Easywave software to draw a 6 cycles sine wave,it can output a 30MHz sine.
But all the parameters of this one is not very good.Maybe this will help you.    ;D

I've recently bought an SDS1022DL DSO and I think I've found some bugs in it's firmware:
- trigger level doesn't match the displayed marker/line/value (and it's offset from real level depends on a trace position) - I've found the same complaint about LeCroy WaveAce 1001,
- in the time zoom mode at a maximal zoom or near to it scrolling of the time window doesn't work or works unpredictably (sometimes when I zoom out and in it starts to work but i.e. only in one direction),
- inverting (even a grounded) channel in XY mode causes its offset for about -500mV, YT mode is not affected.
I hope you can fix this issues in the next firmware release.

I don't think it is a bug about the XY mode, from your video you haven't input anything to the two channels, and when you invert the wave, the phase will change 180 degrees, so you will get an offset. :-[

When there is no signal the dot should in the center of the screen, you can not invert 0, as 0 = -0.
How would you explain that if a channel is internally connected to GND (Coupling: GND) the single dot is exactly a half way between center and inverted "no signal" position. For me it is something screwed up in the firmware and in the XY mode the calibration value is subtracted from the raw ADC value after its inversion, effectively being added to it. While when a channel is coupled to GND the voltage offset calibration value seems to be completely ignored (but only in the XY mode).

The XY mode display connects to the position of two signal, when you change coupling, the position will change.

Post by: tzok on January 21, 2014, 08:28:05 am
There was no input signal, it is just a single dot, changing coupling between AC and DC does not affect dot position. XY mode is very simple (at least in analog scopes, but DSO should "emulate" this), and without the signal the dot should remain in the center of screen, it doesn't matter if input amplifiers are in inverting or non-inverting mode. Inverted 0 is still 0, so it shouldn't move the dot from the center of a screen in any axis.

New firmware which I have received from Siglent have resolved issues with time-base zoom and offset of inverted channel in XY mode.

I purchased a SDG1020 over a year ago, it failed within the first hour of operation, I have gone back and forth with Siglent service many times all they do is stall and give me the "run around". In this unit Power supplies are good, FPGA is good, failure is in the output amplifier stages on the MAIN board. I have requested an RMA to return the unit for repair or return the main board,  and if that wasnt possible I requested a copy of the schematics, (which the salesman said were in the manual, turns out he was refering to the component layout, unbelievable he doesnt know the difference between Schematics and Component layout). Reguardless when it came to time for him to step up and do something he stopped communicating. I hope this isn't indicative of your whole organization. Please restore my confidence in Siglent and help in the repair or replacement of my SDG 1020 and honor your claimed 3 year warranty.
Hope to hear from you soon.
P.S. I will be coping my correspondence on EEVblog forum for all to see the response of Siglent.

I purchased a SDG1020 over a year ago, it failed within the first hour of operation, I have gone back and forth with Siglent service many times all they do is stall and give me the "run around". In this unit Power supplies are good, FPGA is good, failure is in the output amplifier stages on the MAIN board. I have requested an RMA to return the unit for repair or return the main board,  and if that wasnt possible I requested a copy of the schematics, (which the salesman said were in the manual, turns out he was refering to the component layout, unbelievable he doesnt know the difference between Schematics and Component layout). Reguardless when it came to time for him to step up and do something he stopped communicating. I hope this isn't indicative of your whole organization. Please restore my confidence in Siglent and help in the repair or replacement of my SDG 1020 and honor your claimed 3 year warranty.
Hope to hear from you soon.
P.S. I will be coping my correspondence on EEVblog forum for all to see the response of Siglent.

BMac  E.E.

3 year warranty LOL, my brand new Siglent Dso was only out the  box for 3 seconds when it failed and Siglent wouldn't fix or replace it with a model of equal value.

Go back to page 11 and read my recent  BAD experience I had with my brand new out the box shs810 DSO with video of my faulty shs810 and another customer faulty shs806.  In the end both of us had to fix our own DSO without help from Siglent, in my case after trying to get siglent to fix or replace it themselves they actually tried to offer me a product of LESSER specifications as a exchange ( I still have the email to back this up ) so I would go away. Horrible company will never buy from again.


Siglent answers here very selectively:) Maybe you will be more lucky than me:)

He is waiting for the thread to expand way pass the page containing the bad review I gave Siglent on their claim to customer service and standing behind their products both of which are a lie based on my experience with Siglent. They sold me a  lemon and refused to solve the problem.

I've not tried to use Siglent's warranty (but anyways I have a distributor's warranty), but I have rather a positive experience with Siglent's technical support. They respond quickly and are very patient. Currently they have holidays, so they are not responding till the 7th Feb.

Hi support,

two days ago my SPD3303S had a crash.

Power supply buttons where still "working" but display was messed up.

It happened "only" one time in almost 2 year of service, is it a known problem?

Any firmware update (Hardware Version 1.0 - Software Version 1.01.01.01.03R1)?

Hello Siglent Support,

it happens often, that your devices of the SDS1000 series "hang forever" at boot time. As far as I know they do not react to the "Default Setup" button, which would fix it.

This firmware bug is critical.
The user can't continue to work with the device. Only some trick works, which needs a computer connected via USB sending "*RST", "*SAV" as commands. So people who don't use a computer in their working lab have to interrupt their work for more than 5 minutes. People who are not so experienced computer users are even scared by this procedure...

Proposed solution
HOWEVER, I'm realistic. I do not expect you will quickly find all bugs in the firmware and fix them.
Instead, I ask you to implement a kind of "FACTORY RESET" function -IN THE BOOTLOADER- (not within the menu, you cannot use it when the device is frozen). And of course release it as newer firmware revision...

This function shall work like this:
1. The user presses -and holds- the "Default setup".
2. Then the user switches on the device.
3. The device resets all settings to FACTORY DEFAULT and reboots as usual.
4. Optional: When bootup is finished a message "FACTORY RESET SUCCESSFUL." is shown.


I expect that this change in your firmware only needs 1 short line of code in the software. Something like:
>> if (button_pressed(BUTTON_DEFAULT_SETUP)) handle_default_settings();

This just needs to be put -DIRECTLY BEFORE- the code line that loads the saved settings at BOOT UP...
>> load_settings(); // initially load settings


So it looks like this:
>> if (button_pressed(BUTTON_DEFAULT_SETUP)) handle_default_settings();
>> load_settings(); // initially load settings

Note to the developer: In this state the device is ready to -read- the settings memory. So it should be initialized enough to reset those memory region (I assume its a EEPROM). Optionally set a temporary variable "show_reset_message = true;" and after the GUI has been loaded show the message "FACTORY RESET FINISHED!" (or similar).

THAT'S ALL...


This is a very small change. But, it improves the user experience a lot! The brand Siglent would significantly improve by such a small change in the software.
You should implement this function in all your devices (especially in future) and write a short note a short note in the manual in the "TROUBLESHOOTING" section like this "Problem: The device hangs at boot" "Solution: Turn device off. Press and hold the 'DEFAULT SETTINGS' button and switch the device "ON". Hold button until message "FACTORY RESET SUCCESSFUL" appears on the screen."

Even your firmware works perfectly, another user in the lab might set the language to Chinese and the next user of the device isn't able to read it -> can't use the menu function. But, he knows how to do the reset and can just reset the device... now everything is English, which he should be able to understand a bit and might maybe change the language to "German" afterwards.


So... dear support: Please, send a copy of this to the product manager (or directly to the firmware developers, if possible).

Sincerely yours,
Stefan

I think this should be the flat cable problem, the flat cable between mainboard to display screen.
This may cause by shock when you moved it. :-/O

So Siglent Technical support I noticed you haven't posted for a while, stopping right after I called you out on your lies of caring about good customer service and posted vids of the brand new out the box faulty DSO I bought from your company and its refusal to honor the damn warranty. If I had bought a $20 multimeter it would be a expected risk it would not work, but when I spend $600 on a DSO for that money I expect a fully working product but didn't get it and Siglent refused to remedy the problem.

Additionally there has been others here who have asked you to honor your warranty with the equipment they bought from you.

How the heck is Dave still advertising for this company when they blatantly are not honoring warranties for defective products.

Just recently talked a friend out of buying the DSO I bought and convinced him to get a Rigol.

As for advertisements, with the human population, money tends to override any other passing thoughts about whats right or wrong ;)

To bad I did not have anyone to go to in person for advice when I was DSO shopping, but you live and learn and I learned not to buy Siglent.

Well I don't know Dave personally but I hope money is not the reason he would continue to back a shabby liar company like Siglent.

Yes he is.  He is given free gear in exchange for reviews, and he tells them that he will be honest, even if it is unfavorable.  They send him gear anyway.  The only Rigol kit he purchased with his own money was the DP832.  The Agilent scope is a gift from Agilent.  The Tagarno USB microscope is a gift from Tagarno, etc.  There are lots of multimeters he's gotten and there are scopes that he has but just doesn't use, all (or most) were gifts.

I gathered this information by watching Dave's videos and listening to The Amp Hour podcast.

Probably because they're paying him for ad placement.  That's usually how it works.  He displays ads on eevblog.com in exchange for money. 

Typically, display of ads alone says nothing about the page owner's opinion of the advertiser, and you should infer no endorsement by the page owner (Dave) unless it is explicitly stated somewhere.  The display of Siglent ads is a 100% business transaction, opinion doesn't really count into it.

Hello:

Greetings.

I'm not common Siglent technical support. Also my answer may be obsolete because it have been long time after I ask this question from factory.

You have three choices.

1. Use external house reference (connected to 10MHz ref input).

2. Install High stability oscillator (example TCXO or OCXO)  to main board. There is place for it. I do not have detailed information for this. But long time ago I ask it from Siglent and answer was that it also need special FW (what can get from Siglent).


This 3. is my own thinking and not even discussed with Siglent engineers.

3. Modify main board. Take factory installed oscillator out (or cut only trace and leave it on its place) and install example OCXO in. Inject its output to same 10MHz line where was original oscillator output. (voltage etc specs you find using simple measurement on the running unit. 

All self made modifications delete warranty.

If I'm not distributor but I have my own Siglent for my own hobby or professional use. I will think this position 3. If I can not use external 10MHz reference due to what ever reasons. (example if it is used on the work travel or places where is not available 10MHz house standard line.)
Because, this mod also do not need special software and later possible FW upgrades are not problem in this case.

My opinion is that this mod (3.) is quite easy to do but I can not give details for this. (I have not anymore one "service and inspect" unit in my lab what I can use for experimentation.

Inside unit need be careful, and also use normal lab practice about ESD protection.

If installl OCXO it need also care how much it draw current when it start from cold until it stabilize and then, many times they need minutes to half hour to stabilize even first level but reach final stability much much later (retract and ageing curve).

Today good quality TCXO's may  be very good and may be even better than normal middle and even high grade OCXO until go to "State of art" level then OCXO show who is leader but TCXO's are going better and better so, who knows...

If look example Siglent SDG5000 it have far better internal reference inside. (here in forum you can find also tiny test about it)

It depends what are accuracy needs.

Post by: AudioApp on June 05, 2014, 08:01:11 pm
I look also for a high stability oscillator for my SDG1025, the PCB is already made to accept a TCXO (at least on the mine).

I have asked few months ago to Siglent if an internal reference clock option (TCXO) can be purchased for the SDG1025, answer from Siglent Technical Support Engineer was:
"I am sorry but there is no TCXO option to sale for customers"

I have to find a TCXO compatible with the PCB and the way to switch it. For info, the actual 10MHz clock looks like this schematic:

New member, have a few questions...
  • Is it true that Siglent has plans to build an authorized service center in the US?
  • If so when will it be completed?
  • If not, how does one from the US get their Siglent scope serviced?
  • How many firmware updates has Siglent provided for its SDS1102CML scope?
  • What in your opinion are the worst faults and/or best features of the SDS1102CML?

Thanks for your time.
I don't think that the hobbiest market or just Lecroy Waveaces are enough to warrant a full blown "service center." Once they start building more of LeCroy's products, then 10 people in a little Chinatown shack might be warranted.

Well, the first question was really meant for member, Siglent. But it is interesting since a Tequipment sales person respond to a similar question in an email I sent by stating that a US office is the the defining stages. Anyway, after reading many posts about the various brands from this site, I decided on a Hantek scope from Circuit Specialists which is serviced in the US. But in service warranty was definitely a deciding factor.

Well, after much research I finally purchased an Siglent SDS1102CML from Tequipment.net.  So far I love the scope. Here are the things that swayed me from the Rigol 1102.  (Larger display, larger memory depth, Physical knobs for both channels, quieter fan)

I also considered the Hantek's and although the higher res display was a large draw, I didn't want to deal with the funny timebase  (2,4,8).

The only 2 annoyances I have found so far with the latest firmware is the fact that the probe compensation setting is reset to 1X when the Default setup key is pressed.  Also the scope always asks to choose the language on boot.

I hope these 2 issues are addressed in the next firmware revision.

the 2 issues you said are not problems. they are designing issues.
1.default setup 1X is to restore the factory settings. Do you want it at 10X?
2.the language section on boot is for the customers to choose the language easier if you want to recover the version that do not have this section, please update the older .CFG file.

2.the language section on boot is for the customers to choose the language easier if you want to recover the version that do not have this section, please update the older .CFG file.

As Siglent local distributor and also professional with electronics and T&M equipments I will give my opinion what is based to long time experience.

1: I recommend 10X is default.  (note 1) I can give many arguments for this if need.
This is normal recommended setting. Peoples need understand that use 1x probe ONLY if it is nessessary. Normally always use 10x probe. (also because bandwidth but also for safety)
There is many oscilloscopes what as factory default option is also sold with only 10x probes.
Also this is, as well as I know, very common working practice in every lab.
In classroom every school boy and girl need also learn this lab practice in first lesson in scholl electronics lab room. Turn always probe to 10x as default always before and after use if you have probe where is this selection. I hope also today young not experienced teachers teach this.

All  know why there is so much 10x HP and 10x Tektronix second hand nice probes for sale around of eBay etc. This is because professionals "default probe" have been 10X  tens of years.  In long time ago normal package of example Tektronix analog scopes have 10X probes. (and never 1x 10x switchable probes) 


2: It is good that in first power up boot customer get automatic menu for language selection. If example language is "accidentally" chinese and western user who have not yet enough experience with this equipment do not easy find how to set language what he know. It can do it example until boot up counter is 10.

Now it is very frustrating if use more this unit and every start it ask language. Why it ask it in every startup. After weeks, after months.. many times per day if frequently use scope.

I recommend that it works so that when people get it from package it ask language and perhaps example 5-10 first times (due to fact that some shop may start scopes some times for check equipment is not DOA fault. Then after count it shuts off this automatic language menu with normal boot up.

If user want he get this back with using some "deep recovery" option in menu what resets all to exactly factory state, all memories, all user data, even selfcal data.

Wink:
Then also this solution may be clever with many reasons: add something what is example in  old well known Hewlett-Packard (Agilent) many equipments.

Boot up with one or two key pressed during power up boot. It recovers unit to deep factory default state.
It need do so that even if oscilloscope is crash down due to some fatal FW bug and it can not even boot after it (due to some corrupted stored data).

This power up with one or two key pressed drops it always to factory state resetting all, even selfcal data and every user memory and so on "and it drops to ground with his legs as cat". 
After this, also language selection may pop up, all what have been exactly as received from factory exept power up boot counter.


(Note 1: If oscilloscope have automatic probe factor detect then if input BNC is without connected probe, then it need set defaul 1X. This scope do not have this feature.

I think you guys may be missing my point about the 1x/10x issue. It's probably true that 10x should be the default setting, however my request is actually just to remove probe compensation from the list of parameters that are reset when default setup is pressed.

In other words, if you set the probe compensation to 10x, it should remain at 10x even if default setup is pressed.   There are other settings that are not reset when 'default setup' is pressed such as screen saver or 'skin' type. Probe compensation should work the same way.

We know exactly what you mean.
Every DSO that I have had behaves in the same manner, and I would imagine the vast majority on the market also.
BTW I can't remember when I last used the Default button and I've been using DSO's for a good 10 years or more.
If you feel strongly about this start another thread with a poll for or against your idea and who never use Default, with discussion on which brands behave as you wish.
Thread doesn't need to be a slanging match, just a search for a majority view for manufacturers to take note of.

2: It is good that in first power up boot customer get automatic menu for language selection. If example language is "accidentally" chinese and western user who have not yet enough experience with this equipment do not easy find how to set language what he know. It can do it example until boot up counter is 10.

Now it is very frustrating if use more this unit and every start it ask language. Why it ask it in every startup. After weeks, after months.. many times per day if frequently use scope.

I recommend that it works so that when people get it from package it ask language and perhaps example 5-10 first times (due to fact that some shop may start scopes some times for check equipment is not DOA fault. Then after count it shuts off this automatic language menu with normal boot up.

Why not do it the way LeCroy does it on their XStream scopes? During initialization of the scope software there is a button in the upper right corner of the screen which cycles through all available languages (while the scope continues with initialization), and if you want to change the language just press it when your preferred language appears.

If you don't want to change the language then you just ignore it.

I've had some time and I started to experiment with my SDS-1022DL. I've tried to use Teledyne's WaveStudio instead of Siglent's EasyScopeX and... it works like a charm.

...and my other remarks:
P19 firmware has some strange modification to trigger status display which makes it completely unreadable on some time bases (cycling through ARMED, READY and TRIGD’).
Other issue or suggestion is to change the default behavior of time base zoom – currently it zooms to the last set zoomed timebase, not caring about currently set timebase (i.e. working with 10us/div and zoom to 2us/div, then exit zoom mode, change time base to 25ms/div, turn zoom on and... have completely useless 2us/div). I thought that it could be more convenient if zoomed time base would be always initially set to normal time base divided by 10 (zoom x10 like in analogue oscilloscopes).

It seems that my SDS1022DL has died... it was working fine, connected to wave generator, and after changing frequency from 50kHz to 500kHz on the generator it started acting like this:
video@youtube (https://www.youtube.com/watch?v=tETTDlU95GE#ws)
and after restart it changed into this:

So no signal after trigger. When there is no trigger it is kind of working:
video@youtube (https://www.youtube.com/watch?v=Lh6W-iQzwqI#ws)

Any idea what could have happened to it?
I've tried to do push Default Setup button, do SelfCal and flash other firmware (5.06.02.19 and 5.06.02.16) - nothing helps. As far as I can remember it did something similar once before (just after I've bought it, before any flashing), but after restarting it was ok (until now).

I am not sure if this is the best place to ask but I emailed Siglent 5 days ago and am still waiting for a reply.
I am trying to use EasySCOPE with my SDS1102CNL and Windows 8.1.
I have updated the firmware to the latest version : 5.01.02.13
I have installed NI VISA 5.12 and the latest EasySCOPE.
When I connect the scope to my PC I see the 1102 in my Device list as “USB Test and Measurement Device (IVI)” – see attached image.
The USB port on the 1102 is set to USBTMC mode.
When I do Add Device in EasySCOPE I get : “Have not find any device”.
If SigLent are here then please can you tell me how to connect my scope to Windows 8.1 ?

I've had a bit of a nightmare with installing USB drivers to use with the likes of Hantek/Siglent. This is on Windows 7.

The problem is Windows will automatically go and find drivers based on VID:PID over the internet, and decide that whatever it finds is a "newer" driver than the manufacturers actual latest supplied driver. I believe there must be many China manufacturers using the same VID:PID as each other for similar drivers.

The way around it is to delete (and permanently remove) all drivers associated with your instrument from the control panel/system. Then make sure you disconnect from the internet and install the manufacturer provided drivers. The ridiculous Windows automatic driver search will hence fail and you get the proper driver installed.

Also, make sure you set your device up with USB-TMC rather than USB-RAW if you intend to use NI-VISA stuff.

ETA: I have had to go so far as to use REGEDIT and search for VID/PIDs and delete the bastards left behind even after removing the device from control panel!  |O

Thank you very much, that worked perfectly.  :)

I was using the latest version on your SDS 1000CNL page :
http://www.siglent.com/en/product/detail.aspx?id=100000004399111&nodecode=119008001 (http://www.siglent.com/en/product/detail.aspx?id=100000004399111&nodecode=119008001)
You might like to update the version on this page and all other product specific pages.

You might also like to contact Sameer Dhiman so that he can update his installation notes here :

Hi Siglent Support,

I have an SDS 2074 and installed the latest firmware.  I have a question regarding roll mode.  Will zoom function be enabled in future firmware releases?   Today it pops up a message "Function isn't useable"

I thought it was possible to adjust the scale and effectively zoom in this way, but the waveform is not zoomed in on the center of the screen.  So if you have an event you want to zoom in on, you can move horizontal position to find it.  But once you adjust the scale, the event disappears and you are effectively zooming in on a different area. So this is not an effective equivalent of zoom function.

On a side note, I believe others in the forum were interested in knowing if peak detect in roll mode was supported, and it appears to be supported in latest firmware (FYI to forum members).

Thanks,
Don

Hi,

I have the same firmware.  Here is the sequence from default state:

Press Default button
Press Horizontal button
Select Roll mode from menu button
Press stop button
Press zoom button "Function isn't useable" is displayed.

Does this work on your scope?

Also I noticed zoom does not work when decode is enabled.

Thanks,

Hi,

For SDS2074 -- I noticed that I2C decode only works properly when memory is 1.4Mpt or less per channel.  You can select 7M or 14M, but if you do, the decode does not work.  You can see it's trying to decode but messages are not showing correctly.  This does not seem dependent on the sample rate or time base.  System also locked up a couple times but hitting default restored.  By lock up, I saw behavior such as not being able to use Single acquisition if decode was selected. 

As mentioned in previous post, zoom does not work in decode. However, you can adjust the scale after capture and that does work as expected unlike in Roll mode.

Thanks,
Don

I get the same result.
I have not used Roll mode, but will experiment with it and forward any problems to Siglent
For Decode, I Run/Stop and then use timebase and H Position to see areas of interest as you have mentioned.
Interesting comments re Decode and Mem depth. Worthy of more research.

Consider moving this discussion to the SDS2000 thread
Title: Re: Siglent Technical Support join in EEVblog
Post by: don on August 08, 2014, 10:37:22 pm
Also, looks like I spoke to soon on being able to change the timebase / H position with decoding.  The decoded messages get out of sync with signaling when you change the timebase.  So you can't really scroll to see signaling and messages over one another.  There are combinations of memory and time base where you can, but it's hard to figure out how it works.  It think zoom is the ticket since it does not change the sample rate.    Hopefully zoom gets enabled for roll mode and decode because it defeats the purpose of large memory if you are confined to screen view.

Some member asked if you can scroll through list view, select a message and have it take  you to the waveform.  From my testing this does not seem possible in current firmware.

Use a slow TB setting, then Run/Stop, then adjust TB and H Pos to see long Decodes.
Close examination of 1/2 second Decodes quite possible this way.

For example, I'm at 1.4Mpts and 20MSa/s (5ms/div).  It decodes data fine and I see 12 messages but too small to read.  As soon as I change the time base to zoom in, the decoded messages go off screen but the signaling of all 12 packets stays on screen.  Further scrolling of horizontal or changing time base does not help bring back decoded messages.  Unless I change timebase back to 20MSa/s.  It's very odd.

Post by: kwass on August 20, 2014, 02:57:39 am
I have an SDG1025 and like to use a high accuracy external clock with it.  Setting the CLK Source to external works fine until you power off the unit.  When you power it back on the CLK Source will still say "external" but in fact it will be using the internal source until you toggle it to internal then back to external.  This is very disturbing.

In addition the frequency counter function seems to always use the internal clock regardless of the CLK source setting.  I see no reason for this limitation.

Firmware version is: 1.01.01.31R1, Harware: 02-00-00-22-26

Are there any plans to fix these issues in the next firmware release?

Dear Katie,
the first problem about CLK setting, I think this is because the default setup does not include the CLK source setting. I will let the R&D department know that.
the second issue about the counter CLK, this is not a problem, cause the counter always use the inner CLK to count, not every user have a external CLK. Do you want us to add this option to SDG1000 series?

This is less of an issue to me personally than having the CLK source setting remembered.  However, I think it would make the counter more useful, to have the option of using an accurate clock. So yes, I think you should add that option -- or simply use the same CLK source setting that the generator does.

the new firmware of SDG1000 series will be released soon which solved the first problem. we will upload it to our new website at that time.
the second problem is that while you set the CLK source to external , the frequency counter will choose external too. so we will not correct it.

    I want to ask you something about the Siglent windows drivers... I have a Siglent SDG1020 AWG and a Siglent SDS1072CML oscilloscope, both with the same problem... The driver on the CD has a different hardware ID than the actual hardware ID of the equipment... And of course, because of this, Windows won't install those drivers... And even if I change the hardare IDs in the .inf file, the software won't see the equipment...

    The scope and AWG works fine with the NI VISA drivers... but still the same problem... The Siglent software doesn't see anything connected on the USB...

The operating system of your computer is win7 64bit?
You may need install the version  5.1.2 of NIVISA.
It's the link: http://joule.ni.com/nidu/cds/view/p/id/2914/lang/en (http://joule.ni.com/nidu/cds/view/p/id/2914/lang/en)

Hi,

I was getting ready to buy a Siglent SDG1025 but after doing a little bit of research I got the impression that as long as the equipment works fine you are good but if it ever fails it will be a nightmare to get guaranty support.

Is this true? Anybody has any experience getting guaranty support from Siglent?

Sorry, I know is a stupid question but at $350, I would really like to have the peace of mind that if something happened to the equipment it can be repaired with minimum hassle.

Thanks.

But even if I buy from a local dealer, once the local dealer warranty expires (most likely 30 days) I am on my own and I would have to contact Siglent directly and that is were it starts to get scary from what I can see.

Before this past summer we did not have an office in North America so any warranty repairs here had to be sent back to the factory. That is no longer the case since we do have a North American headquarters in Cleveland, Ohio and we can handle any warranty repairs here in this office.

We are currently working on a North American website that will list all of our distributors and local reps here. If you are in the USA or Mexico you might try any one of our distributors:

Saelig
TEquipment
Electronix Express
Emtesco
Circuit Specialists

In Canada:
RCC Electronics
dipmicro

If there is anything else we can help you with please contact us at

Thank you.

Its great news to hear that you guys finally have a presence in North America. Quick question, is www.amazon.com (http://www.amazon.com) an authorized reseller of Siglent equipment?

I had plans on purchasing the equipment from there (http://www.amazon.com/Siglent-SDG1025-Function-Arbitrary-Generator/dp/B00GQNNVH4 (http://www.amazon.com/Siglent-SDG1025-Function-Arbitrary-Generator/dp/B00GQNNVH4)).

If I was to buy from there, would you guys honor the guaranty?

Nice first post. I didn't know the TCXO was an option on my SDG1025, I was considering an external 10MHz source instead.

I'm not sure I would go through with all that hot air, soldering iron, and heated desolder sucker stuff myself, but if you have the equipment why not play it safe, eh?

Good morning.
Yes, the SDG800 family of function generators do have USB Device & Host interfaces as standard. You can download a data sheet on our website if you wish.

I am not certain what all our factory guys will be bringing to Electronica next week. I wouldn't be surprised if we have a SDG800 there. If you are at the show please come by and say hello!

Thanks for the reply Steve. Thus it means that SDG1000 series also have USB host. I am thinking about buying your AWG for hobby use so It would be very nice to see it in advance. Yes, I've already promised to stop by and say hello.  8)

I look also for a high stability oscillator for my SDG1025, the PCB is already made to accept a TCXO (at least on the mine).

I have asked few months ago to Siglent if an internal reference clock option (TCXO) can be purchased for the SDG1025, answer from Siglent Technical Support Engineer was:
"I am sorry but there is no TCXO option to sale for customers"

I have to find a TCXO compatible with the PCB and the way to switch it. For info, the actual 10MHz clock looks like this schematic:

Well the original X1 crystal is clearly 25MHz too, so it makes sense to replace it with a 25MHz TXCO. He also has an SDG1025, not an SDG1010. So I really don't understand your suspicion?

I purchased from Amazon because I know that if I am not satisfied with the product for any reason (even if it’s because I don't think that the signal generators goes well with my furniture) I can return it and get my money back (no restocking free or any other penalty fees). I also have at least 30 days to return the product (more than 60 days if you purchase during the holidays).

You guys have only 7 days returns and it looks like you may charge a restocking fee. If I knew exactly what I was getting and I was sure that I was not going to return the product I would absolutely buy from you guys since I am not too fond of Amazons. Else, the risk is too high.

I guess I just didn't want to be fooled. It shows up that the single poster with the TCXO SDG1025 mod is responsive on YouTube. No problem. My SDG1020 (btw) has the same standard (25MHz) oscillator as did the SDG1025 in the video on YouTube.

Post by: Macbeth on November 13, 2014, 05:37:41 pm
I have an SDG1025 and like to use a high accuracy external clock with it.  Setting the CLK Source to external works fine until you power off the unit.  When you power it back on the CLK Source will still say "external" but in fact it will be using the internal source until you toggle it to internal then back to external.  This is very disturbing.

In addition the frequency counter function seems to always use the internal clock regardless of the CLK source setting.  I see no reason for this limitation.

Firmware version is: 1.01.01.31R1, Harware: 02-00-00-22-26

Are there any plans to fix these issues in the next firmware release?

Thanks,

I agree completely.  I just updated to version 36 and indeed the bug I complained about -- not remembering the external clock setting -- is fixed!  I haven't tested the new features yet but they are a welcome addition.

Valid point.
But if you feel so strongly on this matter I suggest you start a new thread on this in the forum and see just how widespread this "problem" is.
I don't beleive it should be a case of "naming and shaming", but it would be interesting to see how widespread it is in the "gear" that interests the forum members.

I have noted this in a couple of other Siglent SDG1000 threads.  The Sweep function is not working properly after upgrading to .36.  At least on my SDG1005, the sweep is stuck on a repeating up-down pattern with linear only.  Changing the sweep type to log and toggling the direction have no effect on the sweep.  I've tried several different frequencies and sweep times, with no change.  I hope Siglent can make a quick interim fix, because the sweep function is almost useless for my purposes.  If someone else who has upgraded could confirm this issue, that would be excellent.
The new channel coupling function works great!

What is this channel coupling function you speak of? The problem with Siglents updates are they have no changelogs whatsoever, so I don't have a clue and just assume I have the latest and so it must be the best  :-//

Title: Re: Siglent Technical Support join in EEVblog
Post by: commongrounder on November 16, 2014, 10:03:50 pm
When it is turned on, one or the other of the channels can be set as a master, and the other will follow the master settings.  You can set frequency and phase offsets that will track along with changes you make to the master settings.  It all appears to work as expected.

Hello, everyone.

I just wanted to let you know that we now have a Siglent Technologies website for North America:

www.SiglentAmerica.com

It is hosted in the USA and maintained here. We just received the website late last week so we will be doing some editing to clean up the grammar and typos over the coming weeks. At least in North America it should be faster than the corporate website (www.Siglent.com (http://www.Siglent.com)) and we will do our best to keep it up to date, interesting, and informative.
As a note, the latest SDS2000 oscilloscope firmware should be listed there. It was released in October.

We want to make this website useful so if you have any suggestions, we'd love to hear from you at
info@siglent.com

We appreciate your support.
Thank you!

The version on the website is the same version which is on my SDS2204 right now and has been there since I bought it a couple of months ago. There where rumors that a new firmware version would be released by the end of last month but given the number of problems and missing features I suspect it turned out to be a lot more work than anticipated. It's a pity because the unfinished state the current firmware is in is doing Siglent not much good. When the firmware is finished I think Siglent could sell much more (especially after Dave does a proper review).

Concerning the SDG1000 series firmware .36 sweep problem.  I did a bit more analysis and have found that, rather than a linear or log ramp sweep, the user set frequency range is being modulated by a sine wave with a period equal to the sweep time.  We really need to have the lin/log ramps back, at least.  It would be great to have up-down sweeps as an option, but using an alternate lin/log ramp rather than sinusoidal frequency modulation. 
I am sending this to Siglent as well, with the hope that they can implement a quick fix.  I would rather have the partially functional sweep setup used in the previous version .31 firmware, than this, which is pretty much un-useable. :-\

When in doubt I make sure I download it from the manufacturer's website.

Even if you download directly from the manufacture's site there is still no way to verify the integrity of the file unless it has been digitally signed. Digitally signing files is the norm and not the exception nowadays. It is cheap, easy and the right thing to do.

Anyway, Siglent knows about thsi issue now so if they want to do something about it then great, else, it is what it is.

The problem is not hard to duplicate. In version 36 the sweep function simply does not work properly in any way. For starters the sweep goes up AND down instead of up OR down. The up and down setting has no effect.
Title: Re: Siglent Technical Support join in EEVblog
Post by: rf-loop on November 20, 2014, 12:26:06 pm
Problem is really not hard to duplicate.
Whole all sweep functions are now totally wrong in this version 36.
No LOG, no LIN, no selectable up or down sweep. All is now destroyed what was ok in previous version.

It is good to know that if you have accidentally updated to version 36 you can downgrade back to version 31.

How it need work (just ONE example for ONE thing):
Start freg f1  (example 100kHz)
Stop freq f2  (example 200kHz)
Sweep up
Sweep linear
Sweep time t sweep (example 10s)
After these settings output is steady (f1) (example 100kHz)
Then start sweep  example start manually pushing "trig"
linearly (linear freq change related to time) it start rising frequency until f2 and without output freq sweep immediately return to f1 and stop in this case and waiting new trig.
-----
FW version P36

Start freg f1  (example 100kHz)
Stop freq f2  (example 200kHz)
Sweep up
Sweep linear
Sweep time t sweep (example 10s)
After these settings output is steady half way between f1 and f2 (in this case 150kHz)  WRONG!
Then start sweep  example start manually pushing "trig"
it start rising frequency using undefined mathematical function until f2 and then it turns back (reducing frequency) until it reach f1 and then it turn and start rising frequency until  half way between f1 and f2 (in this case 150kHz)  TOTALLY WRONG.  I do not this time know if this sweep is linear or what hell function but in every case it is totally wrong.

If I change now for sweep down.  It do not anything. Still this stupid half way - then up - then down and then up until back in half way between f1 and f2.

LOG sweep. (and up and down) also same.




LOG up need work as in version 31 (exept that LOG  calculation need repair)
LOG down need work as in version 31 (exept that LOG  calcualtion need repair)
LIN up need work as version 31
LIN down need work as version 31


IF Siglent want add other kind of sweep  function...   set center freq and then how much want linearly or log scan out from center freq single shot or continuously wobbling around center......yes this function is welcome for example pass band IF filter adjustments in radio equipments etc   but I think it is better first repair function what have never worked right after launch.

And this is LOGaritmic sweep up or down starting from user defined start frequency to user defined end frequency. .

In version 31 (and just this original ranting about it) was that your math inside FW for log sweep is wrong.  In version 31 it works but only inside one decade difference between start and stop freq.
In version 31 it works example if I select start 10Hz and stop 100Hz (this is one decade - Siglent) but if I want set start example from 10 Hz to 10000Hz or example  from 27Hz to 53768Hz... it do not normal LOG function sweep. I hope Siglent engineers know what is logaritm.

I'm really surprised that before launch and after "repair" this function no one have tested it. Please take even 3 kids from streed and promise ice cream if they test it and tell if it works ok or wrong.

If it is still difficult.

Please go to shop and buy one function gnerator where is log sweep...  and do exercises how it works and then run SDG1000 and look agen if think it is difficult to define and regognize IF there is problem or IF there is not problem.

After this update version 36  whole sweep function is total junk.

Please remove this version 36 from share and set information that peoples who have updated can downgrade back to version 31R1



Btw, what is nice in new FW is that now can lock channels freq. It can set so that CH1  or CH2 is master and other channel follow frequency. Also there can set offset between channels. (but I feel that this offset setting is somehow weird...  I feel better if offset is for slave channel, not for master channel. Master is master and it have its freg. If there is offset then slave have this offset related to master... positive or negative offset. But Siglent think somehow opposite. There is offset, it can be only positive and it is added to master. (display of course show right but still I feel it is weird logic but perhaps other people feel is just ok... I like RPN but also I lake that master is reference and if there is offset it set for slave.)

Problem is really not hard to duplicate.
Whole all sweep functions are now totally wrong in this version 36.
No LOG, no LIN, no selectable up or down sweep. All is now destroyed what was ok in previous version.

...

I'm really surprised that before launch and after "repair" this function no one have tested it. Please take even 3 kids from street and promise ice cream if they test it and tell if it works ok or wrong.

 :-DD   :-+  This is a strange failure of the quality assurance process.

Thank you rf-loop for explaining this problem in the great detail that appears to be needed.  I plotted the frequency over time of this strange sweep and it seems to be sinusoidal in nature.  My dream for this device is they would allow the user to select the sweep type from the built-in arbitrary waveform library, including imported ones, so custom sweeps could be created.  I wonder if the sweep waveform they use is in the same 14-bit 16k-point format as other set/arbitrary waveform files.  :-//

Just confirmed that the sweep problem exist in P36(The sweep code is written in the Remarks ). we feel very sorry.
We will fix it as soon as possible and release a new firmware p37.
We suggest the customer not to update the version P36,

I agree. It seems Siglent does not have a seperate software testing team or department which checks a firmware release against a functional specification. IMHO having a seperate test team is a must-have in order to deliver consistent quality.

Now I just have to install the new TCXO in my SDG1020 and see if it works. It hope it is the right size. It looks so small.

I installed a TCXO on my SDG1025 and I posted a video on youtube.

Thank you for this!

I just made the same mod to my SDG1025 and it worked perfectly.  It's nice to have an accurate generator without having to use an external clock.

This looks like a simple and effective mod.  :)
If I wouldn't care about warranty I'd also do that, along with swapping the fan for a quieter one.
The SDG1025 even outperforms my stone-aged Tektronix 2230 in generating audible noise, it's so annoying!

Marty, that is unusual.
Siglent products are not known for noisy fans.
You are having a bad run.  :palm:
Can you check the blades for dust loading that might be affecting the normally quiet running?

Any others with noisy fans?
Title: Re: Siglent Technical Support join in EEVblog
Post by: MartyD on November 29, 2014, 01:44:35 pm
@tautech:
It's definitely not dust, it seems the fan is spinning way too fast when comparing the noise level to the SDM3055 and the SDS1102CML.
It is even more strange since the lower specificated SDG's do not need a fan at all and the air coming out of the unit is only a few degrees above ambient temperature, even after several hours of operation.

I suspect that some engineer wanted to be on the safe side and threw in a higher cfm fan than needed, just to make sure the unit doesn't overheat in the Sahara. ;D
Or maybe I'm just spoiled by the quietness of my other Siglent gear...

But since I'm already saving up for a 5xxx series generator I'm not worrying too much. :D

My personal SDG1010 makes no noise & I sometimes find it still running the next day.
I might get it out to do a job, set it up and for bench space place it where I can't see the screen so only if I look back after I turn the lights out I might see the screen glowing.  :palm:
But thats only if it hasn't gone into screen-saver mode.  :-DD

EDIT: The SDG1010 has no fan.

I'm not sure if Siglent up-rate the fans in their faster 1000 series AWG's so let's see what Jade has in reply for you here next week.

Only the SDG1015 (IIRC) and higher have fans. The lower frequency models are fanless.

SDG1025 owner here. I have never actually noticed the fan noise, but I guess I am kind of immune to that low frequency stuff. My desktop PC with 2 HDDs is certainly much louder.

I've only just noticed my HP 6632B PSU is a little noisy, though it's not the fan but the transformer resonating through the case. Pressing down on the casing quietens it dramatically. I believe that I can stick on some rubber shock absorbers to the transformer to fix that. I am going to mod it for front binding posts and up the PSU input from 220 to 240VAC anyway.

Yeah, it's subjective I know, but SDG1025 clearly has a fan, but it's well within my tolerance.

I guess dB meters are needed for this kind of thing.

Hello.

SDG1025 owner here. I can also confirm that the SDG1025 has a loud fan. Nowhere near as loud of a Rigol instrument fan but definitely loud if you are working on a fairly quite place.

The sad part about the SDG1025 is that it does not need to be loud at all. Its only loud because they drilled tiny little hoes on both side of the instrument for ventilation purposes. And of course, since hot air does not travel sideways through tiny little holes they ended up needing to add a fan (a loud one to add insult to injury).

I am not expert on instrument design but it seems pretty obvious to me that the generator could have been easily designed to not require a fan at all given enough ventilation holes throughout the case.

Hopefully manufactures will start looking into making their equipment as silent as it can be. I know there is at least one manufacturer that makes a fan-less oscilloscope so I am pretty sure they are paying attention to the issue.

Besides the noise, Siglent also needs to look at the user interface design, I don't mean to be rude but the SDG1025 interface is pretty bad and not intuitive at all. There is definitely room for improvement there.

Thanks.

I have done some temperature measurements on my SDG1025 and the SDM3055.
As it turns out, the SDG1025 indeed needs more air to stay cool, I've measured 30,4°C on the fan. The SDM3055 has around 26°C there, both measured after several hours of operation at 22,5°C room temperature. The SDM3055 is almost inaudible compared to the SDG1025.
As you can see in the picture, both use identical cases, only the front panel differs. Since front-to-back-cooling or bottom-to-top is impractical on a stackable unit Siglents decision to put them on the side makes sense. However, some more passive cooling components inside could easily help making the unit quieter. But I guess it's cheaper to throw in a fan than equipping the internals with proper heatsinks.  :-\

About the GUI of the SDG1025: I never really needed the manual, it took me about 30 minutes to fully understand how to operate it. If there is something I could complain about it's the colors of the outputs. On the front panel they are blue and yellow, on the screen they appear green and yellow. Nothing that can't be fixed in a firmware update though.

The SDM3055 behaves almost exactly like an Agilent 34461A, but it has some extra features and still some firmware bugs which need to be fixed.
Oh btw: I'd be very interested why it doesn't have a hard power switch and consumes 7,4W in standby mode (12,3W in operation).

Thanks for your constructive feedback.
Siglent is always watching and appreciative of quality comments, good or bad along with suggestions for product improvement. These are on-going, both firmware and hardware.
As you are probably aware the careful use of English and its "meaning" is needed for them to fully understand some issues.
Alternativley we agents can and do assist with interpretation/explanation.

I have a SDM3055 coming soon and hope to confirm some of your concerns too.
Looks like I'll be putting a master switch on my test equipment from what you say.  :(

Please keep it coming.  :-+

@tautech:
I apologize for my weird english, it's not my first language and I mostly only need it to read datasheets. ;D And yea, I try to be as constructive as possible.

Regarding the soft power button on the SDM3055: I can only imagine that some circuits are still powered in standby mode so the Meter doesn't need to warm up after switching it on. I cannot imagine the flashing LED consuming over 7W just for fun. But only some explanation from a Siglent engineer could enlighten us about this.  ;)

Also, if anybody is interested, I could make a video review about the Meter.
I was promised a new firmware version in a week from now on, so this would be the ideal time for a first review since I now know the Meter, it's firmware and the quirks good enough.

I have criticized it in SDS2000 series oscilloscopes.

This "standby" / "on" power switch alone without real 2-pole hard switch  is not at all good practise. I do not think so much power consumption in standby mode  (but also it is not acceptable)  but also safety.  I have in my lab well over 20 equipments allways ready for use + others. If all these have only standby switch whole orchestra take allways well over 100W in standby, say example over  150W estimate.  It means 3.6 kWh per day and over 1300kWh/a!  Just for nothing! (exept in Finland witer time it is part of house heating, but opposite in summer time when need use power for cooling extra heating)

But there is other aspects.

If psu fails it may itself made short or some other not so nice things. If it fails night time when equipments are alone, it may produce smoke and lab fire alarm go on.  I know there is also equipments what really need be stand By or even powered. Example frequency reference (house standard) and some equipments what have higher precision OCXO. Because shut off OCXO means frequency retract and it may need days for walk back to ageing curve this retract.  But even all these equipments have hard switch. And in well designed equipments hard mains switch is always 2 pole switch. (many chinese equipments have only 1-pole mains switch and it switch in most countries live or neutral wire. In some equipment and if some user have not grounded his equipment.... switching neutral off and leaving live 230Vac on is also least potential danger = this stupid one pole swith practice need also stop!)  Also some times mains  have breakouts and spikes...etc.

 If I have power I will set rule without exeptions that every T&M equipment, powered directly 110-240V mains,  need 2-pole mains switch without any exeptions.  Yes some can say there is mains plug and you can pull it out. Yes  --- there is, but...

I do not like system where cheap simple switch mode psu is always connected to mains and partially working, least primary side. 
Also all these generate EMI.  If I want EMI/RFI true silence, now I need plug out these equipments from mains because they do not have hard switch. Not good at all. many equipment need be on only if need use it.  (exept these what really need standby for accuracy stability)

I can not find any positive argument for leave hard 2-pole switch out from construction but I find lot of arguments why it is bad.  My opinion is: Really bad "fashion" but this is not alone Siglent. It is common "problem".

Hi Marty,

Since front-to-back-cooling or bottom-to-top is impractical on a stackable unit Siglents decision to put them on the side makes sense.

Good point.

But even if side to side cooling was the only way to go, I think the current design could be vastly improved by simply making the air holes a lot bigger and throwing in a bigger slower an more quiet fan... at-least that is my feeling.

About the GUI of the SDG1025: I never really needed the manual, it took me about 30 minutes to fully understand how to operate it.

This is because the SDG1025 is a simple piece of equipment (it does not do much) but that does not take away the fact that the current user interface is non-intuitive. Put simply, there is no reason why things need to be more complicated than they have to be.

Thanks.

However, to "protect" my electricity meter from soft power switches I use these all around my house:

Hi,
I sent this to support@siglent.com but received no reply. So I'm trying hoping that someone can help me figure out if the unit is malfunctioning or it's an user error:

-----

I'm trying to capture and analyze an occasional, non-periodic signal with my SDS1072CML .

I can do that without any trouble in the "Normal Mem Depth" mode;
- I just set the time to 50ms/div
- set the trigger to be triggered on the dropping edge
- set the trigger mode to "Normal"

when the signal arrives, I see it on the screen, I can zoom in to see the details of the signal or switch on the "delayed" mode by depressing the time knob. I can even stop the capture to prevent the next signal to re-trigger. All works as expected every time: so far so good.

But if I set the "Mem Depth" mode to "LongMem" then almost nothing works:

With the LongMem mode, sometimes I see the captured signal when it's triggered, sometimes I don't see the signal even after I zoom out to see the whole captured data. If the signal is there, turning on the delay mode behaves in a weird way: the bottom detail view doesn't pan with the position knob and it either shows a garbage data or a previous signal, not the one I've just captured.

It behaves as if the longmem memory modules are not recording and/or recalling the data properly (memory corruption?)

long mem feature is very important for this task as I need to analyse a long signal in detail, normal mem depth doesn't give me enough detail.

Please let me know what I should I do.

Thanks

I have just received my Siglent SDS 1102CMS and posted a thread on here before realising this thread exists. This is seems to be the ideal place to get a direct response and support from Siglent.

I have read quite a few pages of posts in this thread and I am very impressed Siglent have handled the various comments, demonstrated they are listening and are prepared to respond and implement changes. This is most welcome and also unusual for a manufacturer. It can only help boost confidence within the user community.

I am building a model railway layout which includes many electronic modules, all connected together with a CAN BUS. I had an PC oscilloscope previously but found that support was poor and the unit quickly became obsolete.

Now to get back to my Siglent questions.

Packaging was very good and I quickly set up the Oscilloscope and probes. I then went on to install the software but found that the integration did not work. I am using Windows 7 on my PC and it did not identify the scope nor any driver for it.

1. I was advised to download the software from the Siglent site which I tried to do. The site informed me that I must be logged in. I tried to register many times but each time it failed to accept my registration attempts. Looking at the pattern of failures it would seem that the fact I am retired and not working for a company was the source of the problem. The name of my Unit/Company was the only question that still had a query against it. I had to give up. Can Siglent please look into this and advise me how I can register? Unless registered, we cannot get any support as feedback is also barred unless you are registered.

2. The version of Easyscope that I received on my disc has a release date of mid 2013. The site version has a release date of Sept 2014. It may well be that my scope was manufactured and shipped before Sept 2014 but it would be better to give copies of any new pc software to the retail distributors for shipping with items still held in stock for sale.   Could Siglent please consider this?

3. I now have a copy of the new software. I cleared all the previously loaded software from my computer then installed the new version of easyscope followed by NI visa512runtime.exe which was also included in the zipped package. I then opened up Easyscope and then connected my scope to the PC running Windows 7. The scope was not seen in the Easyscope program. I check my Printers and Devices PC utility and found that it was now correctly identified by model number but without a driver being present. Could Siglent please advise me of the actions I need to take?

Well that's all for now.

Just enter anything in that field, Peter.  I find that "Stuff and Nonsense, Inc." works pretty well.  :)  It's not like it's going to run a corporate search, and reject anything it can't find.  They're just data mining.  Heck, if enough people did that, it may someday show up in their Marketing literature, with "Stuff and Nonsense, Inc." listed alongside other major company customers, who have bought their products!

Ouch.  No.  I understand the sentiment, and why that might seem handy to you, but things change too quickly, and what you're proposing would be a major PITA (for manufs.), and add more expense to the distribution chain.  Plus delay getting units out to customers.  None of which is a good thing, in my book.  So, please, no.


Besides, requiring registration before downloading software that works only with your device is in itself foolish, IMO.  Your software should run in a demo mode if no device is present, and thus act as enhanced advertising content (if its any good).  I know why Marketing does this, to bulk up their mailing lists, but I'm not sure when I enter my Contact info as:  Bilbo Baggins, 12 Middle Earth Ln, etc. it does them much good.  ;)

Now I just have to install the new TCXO in my SDG1020 and see if it works. It hope it is the right size. It looks so small.

is there a measurable difference?

I installed the TCXO yesterday and used the SDG1020's frequency counter to measure a 10 MHz Morion MV85 OCXO (Uin not connected, so the frequency is pulled >0.5 ppm (between 5 and 10 Hz) below OCXO middle value)

With the original 25 MHz crystal installed, the SDG1020 measured 9,999830 MHz (-17 ppm) 9.999849 (-15.1ppm)
With the 25 MHz 0.1 ppm TCXO installed, the SDG1020 measured 9,999996 MHz (-0.4 ppm)

EDIT 2015/03/13: My SDG1020 with the 0.1 ppm Vanguard TCXO outputs 9.9999990 MHz when set to 10 MHz (that is exactly 0.1 ppm low). Measured with a HP 5315A frequency counter with OCXO option installed, calibrated using a Rubidium (FE-5680B) frequency standard.
*********************
My HP 5315A measures the 10 MHz OCXO a little high, at 10.000015 MHz. No longer the case - standard XO replaced by OCXO

2 hours ago, I ordered the parts at Farnell that I need to fit the MV85 OCXO onto the PCB by amc184 that goes into the 5315A as the new frequency reference. And now I just received an email from Farnell stating that the order has shipped from their warehouse in UK. Pretty fast handling. I will not be surprised if the shipment is delivered to my door (in Norway) by tomorrow.

EDIT (17 hours after order was placed):

2. The version of Easyscope that I received on my disc has a release date of mid 2013. The site version has a release date of Sept 2014. It may well be that my scope was manufactured and shipped before Sept 2014 but it would be better to give copies of any new pc software to the retail distributors for shipping with items still held in stock for sale.   Could Siglent please consider this?

3. I now have a copy of the new software. I cleared all the previously loaded software from my computer then installed the new version of easyscope followed by NI visa512runtime.exe which was also included in the zipped package. I then opened up Easyscope and then connected my scope to the PC running Windows 7. The scope was not seen in the Easyscope program. I check my Printers and Devices PC utility and found that it was now correctly identified by model number but without a driver being present. Could Siglent please advise me of the actions I need to take?

Well that's all for now.



2.
Here can download EasyScopeX-EN.rar (https://app.box.com/s/ps4t59hd9n18rkvr3ucf) (version 02.01.05)  82,3 MB (86 304 331 bytes)

It include compatible NI-VISA runtime and also .chm  help file (.rar is just exatly as it is from Siglent).
This is last version downloadable also from Siglent (main side).

3.
It is long time I have installed (other older version) EasyScopeX what also needs NI-Visa.

If I now remember right, it must install so that first install ni-visa.


(in my case it was some manual work for clean Windows USB related things and so on after first time wrong intsllation "hassle". (but this time Siglent did not distribute even Ni-Visa...)

you need to install ni-visa runtime first and then install easyscope. set the oscilloscope to USB-TMC mode.

Many thanks for your reply.

Logging on to the websites.
I have tried both websites and still cannot log on the public account. (See attachment 1)

Dealing with unsold stock when a software/firmware revision is released
The simplest way of dealing with this, requiring no additional work, could be to add a comment in the quick start manual giving the url to the support page for the instrument with details of how to log in on the public account.

Installing EasyScope X
I made the mistake of loading Easy ScopeX first. I removed both EasyScopeX and the NI visa512 runtime programs and reinstalled them in the order you give. The scope still does not appear in EasyScopex. The html document (Introduction) says Microsoft .NET framework version 3.5 is required. Windows 7 automatically installs this as part of the Windows package (see attachment 2). I am running Windows 7, Service  Pack 1.

I have checked my Devices and Printers folder within the Control Panel and confirmed that the scope is properly identified. I troubleshooted the scope and found that Windows could not identify a driver.

Thanks very much for your reply. Sorry for my delay in replying to you but I have just received seen your and Siglent's replies and wanted to try out the advice Siglent gave first. The order of loading the two pieces of software is not obvious in the documentation but Siglent advise the same order of installation as you do.

I think the big issue here is not associated with any of the software packages but the lack of a USB driver for the scope. Without this, there is no hope in connecting the pc to the scope. I understand why the run time programme is required as well as the .NET framework but both of these pieces of software cannot establish a scope driver. This surely is the manufacturers responsiblity.

Is it possible that after some mistake in installation there come "Windows secrets".

After uninstall all installed things Windows do not forget what is writed in infcache.1 (there is stored allready installed USB drivers info. Widows do not clean it. Sometimes it may do troubles. We all also know this famous phrase in many purchased equipments USB connection. "do not connect USB before you first...etc...". No one exatly know why this hassle with USB continues years after years by Microsoft....)

Then you plug in your scope and there it is, wrong inf, agen and agen.

In some cases it may need manual fix.

Some idea can get example here,  but do not follow directly, only get some idea if really need reset some individual USB problem case)

After any change introduced in Windows, I always reboot the system to ensure that everything is removed, regardless if Windows asks for it or not.

This is what I am asking Siglent to do. I believe that Siglent are serious in making improvements for the user, based on previous replies on this thread. A little more thought in the instructions would go a long way to achieving customer satisfaction. BTW, I am starting to use the scope as a stand-alone item and I am very pleased with the results so far. This is a great improvement over my previous model.

I have unzipped the file and successfully loaded the driver. I ran EasyScopeX but the scope did not appear in the program (I did select USBTMC from the option menus when Add Device was selected).

I have the driver in a folder within 'my documents', Perhaps it should be placed elsewhere.

SDS1000 series connects no problem to the previous Easyscope3 after a simple install.(DSO not connected during install)
However Easyscope3 is no match for EasyscopeX for usability and functionality.

Yes it seems SDS1000 series connection is problematic to ES X.
Drivers accepted and has active/valid USB connection but DSO not seen by ES X.

But it needs sorting out with clear guidelines for a seamless trouble free install.

I'll point Jade at Siglent to this, he will have the answers.

Thanks for your help. I never believed I was completely alone with this issue and fixing it will avoid others having the problems I have experienced.

I shall wait for a solution and continue to use the oscilloscope as a stand alone item. It would be nice to be able to print the test results but I shall try to photograph the screen as a record (my printer is wireless).

@ PeterSD
Use a USB pen drive to capture screen shots in the meanwhile. Use the white "Print" key.
This is probably the most common way of recording waveforms.

Easyscope provides a better "linked' solution but its easy to open the USB capture in a picture viewer, then send to printer or compress them to a more manageable size for documents or to post here.

My advice re scope use and Auto Set.
Resist the urge to continually use it.
It omits all previous settings, some often laboriously set.

Learn the features and capabilities of your DSO and how to apply them to best effect.

A dream to use. It certainly will be a good stop gap until the PC connection is fixed.

Thanks also for your advice on using Autoset. I was just being idle to get the reference waveform on screen. At last I can use the scope properly for the purpose it was purchased.

Versions of my SDS 1102CML

Software 5.01.02.22
Hardware 11.62-3.5

I am running Windows 7 Service Pack 1

To make another clean start, I removed EasyScopeX and 3.5.2 Run time from my computer and restarted windows to complete the un installs .

I watched the video and downloaded the software in your link above 

I tried to install .Net framework 3.5 Service pack 1 then ran into some issues (see images below):

From this I conclude (as I have previously said) that my version of windows already has net framework 3.5 Service pack 1 installed
as part of the standard windows package. The warnings suggest that the installation I have tried to make is an OLDER version. From what I have read, .Net framework is backwards compatible and therefore I need not have installed it.

I am stopping at this point but shall continue when I have confirmation that I can proceed.  (http://www.siglent.com/2014EnglishWebsite/Firmware&Software/Software/EasyScopeX-EN-B02D01P05.rar)

Ed: It looks like now (or after I downloaded)  information is added to download side. (but not corrected in update instructions pdf.)

If CFG file was installed at the same time as the ADS file (main update) I don't think there are any problems.
I got the CFG file installed an hour or two after the main update, without it the sympton is a boot screen fault.

AFAIK the order of install for the 2 files does not matter, just they are both needed.

Why the firmware was 2 files I am not sure, they are usually only 1 file.

Also SDS1000L models have .cnf file.
This is just "wild speculation" (or not so wild). It include "perhaps" boot screen image (and some other information).

Perhaps I can make my own boot screen with my brand.

Hello, I posted in another thread about a potential problem with my SPD3303D power supply.

It seems that the current meters do not work correctly in series mode. Current is only measured for channel 1 (and whatever is displayed on channel 1 is displayed on 2). This is ok when a load is only across both supplies (current would be equal here, still shouldn't be assumed), but load between common and either side while in series mode, current is only measured for channel 1. Channel 2 will show 0A when load is across common and channel 2. Likewise, when the load is only between channel 1 and common, channel 2 meter shows the same load as 1, with nothing connected.

This seems like a software bug, if they're wired in series externally with a jumper, everything works as expected. Maybe hardware limitation, I would assume pressing series just places a connection between the to the same as an external jumper and sets the software to lock the two channel control together so they track (option to not track should be included)

Attachments show connections with load on only one side at a time in series mode.

Additionally I'm unable to update the firmware, it says "This file does not match the device!"

Any ideas, am I missing something?

Details are in the post:

*** SHS1062 Problems ***

Hello, I just would like to ask if there will be ever again a firmware update for the SHS1062 because there are still "some" problems ...

The scope does work pretty well in short timebases and "short memory" mode. But the scope almost doesn't work at all in "long memory" mode longer timebases.

So problems in "long memory" mode ...

- In shorter timebases after stopping the scope it is way off the trigger point.

- In longer timebases there is no indication if the scope really is ready for the trigger or if it is still filling the memory before the trigger point. With a 10s/div timebase and the trigger point in the center I guess it does need about 2 minutes to be ready. But there is no indication for it. After stopping the record it also can be, there is nothing on the screen of the scope ... so it is really not possible to work in this long timebases with long memory at all.

- After recording with 1/div the timebase is wrong after zoom in (picture below).

- Also other longer timebases it mix up things also (2nd picture below) but at least the timebases are ok.

- Why are single shots just in short memory mode possible?



There are also some other smaller things ...

Scope Trend Plot:
- The probe (x10 or wathever) is not included. So the showed value is the "wrong", 10 times to small with a x10 probe.

- When the scope is stopped and you would like to start the recorder just channel 1 is showed but not channel 2.

Scope Recorder:
- Zoom in doesn't work well ...

Over all the scope:
- The colors combinations at least in inverted color mode (black background) are not not always chosen so lucky (yellow letters on green backround).

- Different color for the traces. In scope mode ch1: yellow/ ch2: light blue. In recorder mode ch1: blue / ch2: red


Scope measurement function:
I guess I never used to do use measure functions with another scope but I guess something is at least a bit wrong or bad implemented, so ...

- It seems not possible to measure the Phase shift between Ch1 and Ch2 if not both are clean sinus waves. So it is not possible often to measure the phase shift between a voltage on Ch1 and a current Ch2 (from a clamp).

- So I did measure the time from when the voltage goes thru 0 from Ch1 and Ch2.
Source > Ch1 / Type > FRR
The problem here is, example 50Hz/ 20ms per wave, if Ch2 is more than 10ms behind, let's say 15ms behind, the scope just say
FRR:5ms
I think it should be 15ms with Ch1 as source (or at least -5ms).


Scope with Filter:
- When the scope is running everything is fine. But after stopping just the original/unfiltered waveform is showed ... and the filter function is turned off in the menu, so you have to enable the filter each time again after stop/start ...



Firmware : 3.01.02.01
Harware : 1-21-3.3
Serial No : SHS000031300x (I guess the last digit doesn't matter)


Special the thing with the "long memory" mode bothers me because I bought the scope because of the 2Mpoint memory. Also the filter thing, I often use the filter in combination with the AC/DC current clamp on smaller currents to get a cleaner waveform.

I don't understand why there is for over one year no firmware update again for the scope.

Apropos "over a year" ... happy new year anyway  ^-^ ... I hope to see new firmware soon :-\

Hi Siglent,

in the other thread, https://www.eevblog.com/forum/testgear/siglent-spd3303d-series-bug/msg581704/#msg581704 (https://www.eevblog.com/forum/testgear/siglent-spd3303d-series-bug/msg581704/#msg581704) , I've described the problem I have with my SPD3303S power supply. Apparently, they've silently revised the board, rotating the LCD 180 degrees and after I've upgraded my (presumably older version) hardware with the latest firmware posted on the Siglent website, everything displays upside down. There's no mention on the website that it's only applicable to some of the SPD3303Ss. I got in touch with Siglent but all they could offer was the firmware version even older than what I had before: 1.01.01.01.03 vs. 1.01.01.01.03R1. That's a really weird situation, please help me solve that.

Greetings again!

I wanted to let everyone know that if you happen to be in the Silicon Valley area of California the week of January 25, Siglent will have a booth (#1245) at the DesignCon show at the Santa Clara Convention Center. Exhibition days are January 28 & 29. Two of us from Cleveland will be there as well as one of our factory people.

If you are planning on attending the show we would love to say hello so please stop by! We will have several new prototypes of equipment coming out later this year, including one of our new spectrum analyzers.

Warm regards,
Steve

There is a 1.5/1.8 GHz model and a 3 GHz model. The unit I saw had a tracking generator and the EMC tools. I don't know if they are standard or optional. It was a really nice looking unit. We showed the 3 GHz version at Electronica. Specs should be better than comparable products in this price range. I believe the display is larger.

That's all I can say at this point. I hope to learn more at DesignCon.

Dumb question.....

Is the 50 ohms output impedance on the SDG1025 function generator always present even if I setup the Load parameter to be equal to "High-Z"?

My guess is that the answer is yes but just wanted to triple check. I assume that there is some kind of a physical 50 ohms resistor welded right before the BNC output connector so it is always there no matter what parameter you set in the function generator.

Could someone verify this for me?

Thanks.

Dumb question.....

Is the 50 ohms output impedance on the SDG1025 function generator always present even if I setup the Load parameter to be equal to "High-Z"?

Simple answer. Yes. Output internal impedance is 50ohm INDEPENDENT of what value you set for LOAD impedance what setting affect only for displayed V level so that you need not yourself calculate it. Adjustment is NOT for adjust internal impedance. Adjustment tell to SDG what is your LOAD impedance. If your LOAD impedance set is right, only  then SDG display can show right Voltage level.

Inside  is "zero impedance" source -- internal impedance 50 ohm ---BNC out --- your LOAD impedance --|

>---Ri--OUT--Rload---GND

Example:
If you set HI-Z as load setting... and your SDG V level show 10V. You connect 50ohm load to output. Your level over your load is 5V.  (source voltage 10V and series 50ohm Ri and 50ohm Rload)

If you set HI-Z  as load setting... and your SDG V level show 10V You connect 1Mohm load to output. Your level over your load is around ~10V (source voltage 10V and series 50ohm Ri and 1Mohm Rload)

If you set 50ohm as load setting... and your SDG V level show 10V. You connect 50ohm load to output. Your level for your load is 10V.  (source voltage 20V and series 50ohm Ri and 50ohm Rload)

If you set 50ohm as load setting... and your SDG V level show 10V. You connect 1Mohm load to output. Your level for your load is ~20V.  (source voltage 20V and series 50ohm Ri and 50ohm Rload)

(it is also in data sheet and it is in manual)

Post by: Rene on January 22, 2015, 08:56:02 pm
Guys, thank you for helping me out with my question.

Before posting, I did run some experiments and I also concluded that the 50 ohms resistor was being used regardless of the Load setting chosen (50 ohms or High-Z). The problem with those tests is that they were not really conclusive (at least I think they were not conclusive).

For example, lets say that this particular function generator had two transmission lines leading up to the BNC output connector, one with a 50 ohms resistor in series and the other without the resistor. Because of this physical design, this would mean that it may be possible via some software setting (on the current or some future version of the software) to actually bypass the transmission line with the 50 ohms resistor.... Yes, i realize that my example is a dumb example but I am new to all this and right now I feel like a hormone raging teenager checking out their very first porn magazine, my mind is going all over the place!

So anyway, what I wanted to verify was that it was physically impossible to skip the 50 ohms resistor due to the hardware design. in other words, there is only one transmission line leading up to the output and such transmission line has a 50 ohms resistor welded in series on it so it is impossible to bypass the resistor via software. Based on the replies, this appears to be the case.

Thanks.

Riggght. Pull the other one, which plays Yankee Doodle.

As an aside, spot the misconnection on this Samsung TV set at my bank ( the Steve Bank) that purports to be "Made in South Africa" as well. Local TV set manufacture stopped in 1996 when the assembly plant in PE closed down, due to cheap imports. Even then they had been reduced from a full house manufacturer doing everything from design to panel and case manufacture to a kit assembler who got the local content mark from closing the back panel, placing the set in a box with a locally printed manual and placing a pair of batteries in a pack with the remote.

The audio out goes to in cieling speakers, that are powered and make a very quiet hum. Luckily they plugged the mini jack into a video component Input jack. One to the left is video out....... Sad to say the video feed is via the RF link, not via the VGA input though there is a cable attached to it, leading to a computer somewhere. Kind of a waste having a HD monitor, and feeding it a standard video signal instead of using it to it's best resolution.

Just what OS's warn of a file not signed? I only use Windows and wonder if other OS's wave the red flag like it does.  :-//

IMO its the file source that most important and that file's suppliers efforts to ensure their repository is secure in order to protect their customers.
Is this view naive?

Post by: Docholiday on March 14, 2015, 10:21:56 am
It is exactly as tautech stated what is most important is the manufactures server where these files reside. This is the critical path for file security. Reliance of an embedded code is only a deterrent. To safely secure a file one would have to provide a form of encryption. The encryption process would have to be a two part encryption simular to what pgp encryption provides - public and private keys. This would be expensive for any manufacture to maintain, provide for their customers, and available globally. So it comes down to cost and the only viable solution is to embed a code into the file. Look at as a unique sticker that says "Made in America". When installing this software it will look into a data base more than likely on your computer to see if this software matches a code that is in that database. If not it will tell then display the file is not digitally signed. Some manufactures require you to have internet access not just to download the file but to check the digital signed process on their servers (two part process), that is a better form of file security. The database is part of your frequent security updates. It is a simple method to determine what is used by downloading the file than turn off your Wifi and start installing the file. If it installs successfuly that digital code is being read fron a database installed on you PC. If not it will tell you that it could not access or install because of no internet access.

This method of digitally signing a file has been around since the stone age! We use to call it checksum. So take all this with a grain of salt. Keep up with your OS security updates and OS and application updates too. Most importantly, virus and adware applications are updated too. Follwing these simple processes will minimize your exposure to viruses, adware, and malware. Only download/install files from  sources you know and trust. Google them if you are not sure.

Post by: Rene on March 15, 2015, 07:07:55 pm
Perhaps we are talking about two different types of digital signature. The digital signature that I am talking about (The one that is used by the Windows operating system to guaranty that the downloaded file has not been tampered with) is nowhere near a simple checksum value (not even close).

To digitally sign a file, you must first get a code signing certificate from a trusted certificate authority and use that certificate to sign the file (this certificate consists of private and public keys). In order for someone to digitally sign a file on your behalf they must have the private key which they will not have. This type of digital file signature is not a mom and pops solution, it uses strong encryption and it is de facto standard (as far as I am aware of) to guaranty that nobody has tampered with the file.

A quick internet search yielded the following links describing the process:

http://en.wikipedia.org/wiki/Digital_signature (http://en.wikipedia.org/wiki/Digital_signature)
https://www.comodo.com/resources/small-business/digital-certificates3.php (https://www.comodo.com/resources/small-business/digital-certificates3.php)

It is true that downloading files directly from the owner’s site is always better than downloading the file from some bogus site but it is still not a convincing way to guaranty that the file has not been tampered with.

Regarding the comment about the cost of obtaining and maintaining a digital signature certificate. This is not an issue at all. Obtaining a signing certificate is dirt cheap and signing a file is extremely simple, I know this for a fact. But no one has to believe me, just look it up and you will see.

The bottom line is that it is irresponsible for a company to take chances on customer security matters by not digitally signing their files (in Siglent case, they need to digitally sing their zip files). Sorry, don’t mean to sound rude but that is just a fact.

In any event, as someone else mentioned, I doubt that these guys could care less, this will become evident by the fact that Siglent will ignore this posts and pretend this is not an issue. Too bad becuase I do like Siglent stuff and I really wish they cared.

Really.....thats strong language.

The facts are SIGLENT are on this forum searching for any problems their customers are having ON A DAILY BASIS.

As the Siglent network (CN, EU & USA) is very engaged with this community along with others like myself, they offer almost 24/7 support for their products on EEVblog.

I understand your concerns and others no doubt do too, but point us to problems that have arisen as a result of unsigned files from Siglent.


If this was a REAL issue I'm sure it would have been addressed by now.
Siglent USA will be very aware of these general concerns and quite likely are working in the background to address this. I imagine unsigned files are not a concern in eastern markets like they are here, probably a hanging offence to tamper with files there.  :-DD


In relation to ignored posts, Siglent sees all posts but even for me some are difficult to understand.
Some are reported to Siglent and they come back here for more information from customers.
The language issue is sometimes a problem, but name me a Chinese company that doesn't have this problem.

All requests for help must be as clear and meaningful as possible to be fully understood.

Thanks Tautech,

I am not going to deny that I probably went a little too far with my comments (probably uncalled for). I was aiming to get a reaction from Siglent since this is not the first time I have brought up the digital signature issue to their attention and they have ignored the issue before.

So lets play by the rules here and be fair. That said, here is my question for the Siglent folks:

Dear Siglent, could you guys please be so kind as to let your customers know the reason for why you don’t digitally sign your files?

Thanks.

I am sorry you feel that way. I provided you with links that explain how digitally signature works, if you take a minute to read up on the technology you will find that a digitally signature is currently the most secure way for authors to protect the integrity of their files (this is no checksum). This is not my "belief", this is a fact.

For fun, you may also want to check out the requirements for developing apps for the iPhone, iPad, Android, Windows phone etc. You will soon find out that all require you to digitally sign your files. Care to find out the reason why?

That said, if you think I am an ignorant troll that knows nothing about digital signatures then fine, you can color me ignorant, no problem, in the mean time, why don’t you give Apple, Google, Microsoft etc a call and let them know that digitally signing files is an absolute waste of time and they need to stop the nonsense, see what they tell you.

I am going to end this now...

This not the platform to school you or anyone else about Information Security concepts and best practices. Do more research and you will find there are more than one method of digital signature processes. The biggest problem with digital signature technology (public & privtate method) is who holds and manages the private key. That is where the vulnerabilty is - lost keys, mis-managed keys, stolen keys and as someone pointed redirects. That is why (of many reasons) in the USA the government does not allow the use of legal documents to be signed digitally. Exept Connectictect but only between corporations. Again, this solution is only a deterent.

In closing this issue I realize after reading my previous responses. I may have been a little harsh in my response, as this was not my intention. I have issue with very short patience when statements are made in a haphazardly fashion. I guess its my 35 years total as a computer forensics expert.

Sigrok is a signal analysis software package. It's open source and free. The program works with around 140 devices at this point. This includes logic analyzers, DSO's multimeters, power supplies and so on. The package operates on Linux, Windows, Apples, Androids and some others. It has an excellent (and ever expanding) set of protocol decoders. It's a project that has been moving forward and is growing.

Reasons for helping out sigrok?

- Hantek and Rigol have supported hardware, so should you.
- Siglent has some older and low cost scopes that could benefit from the software features. Use on an Apple or Android platform for one. That is a platform you don't support.

Hi, Siglent. Do you think future firmware updates of SDG5000 family will enable channel coupling function, if hardware supports it? Thanks  :-+

HW supports it. Also I hope Siglent add this function in some future FW.
Channel lock so that user can select what channel is master and then user can set offset frequency (including 0Hz offset of course) between channels and then slave channel follow master when user change master channel frequency.  Also so that user can set phase angle offset between channels and when channels are in this lock mode  it keeps phase offset when user change master channel frequency.

It is nice to see that after 4 yars Siglent still add new features to SDG1000 series. But, it is also important in SDG5000 series. (And I believe they do not have stopped developing it)

Language select after startup.  Personally I do not like it and I know many other who do not. (I can not understand who need this feature) Perhaps some school users?  Perhaps it is better to add some kind of "techers" power up when teacher can power up machine to some initial state after kids have played with it. Example push one button startup what delete all users settings and give also language select menu visible after this special "deep reset" startup.   (keep one key pressed during power up and it do this deep reset to state where it is as new unit or something like it)

I agree with Docholiday: Keep the anti malware & virussoftware on your PC up to date and look where you download files from.

There is no way to ensure that even a signed file is really from the author if you don't check where you download it from. If you have malware on your PC which redirects a web request to a different server (this is really easy to do even with secure connections!) then you'll happily download a signed file from a malicious source.

I meant to post this earlier but I got lazy. Nevertheless, I wanted to address your post to help clarify some of your misconceptions.

Two of the main benefits that a modern digital signature provides are:


If you are using Windows OS, you can view the properties of a file (by right-clicking the file and selecting properties from the context menu). If the file has been digitally signed you will see a tab from where you can get more information about the digital signature (see Picture 1).
 
If you click on the Digital Signature tab, you will have aces to all kinds of information regarding the digital signature, but one piece of information that you will find relevant to your post is the digital signature certificate (see picture 2).
 
Looking at the digital signature certificate (Pciture2), you can be sure of two things:


So to address your comments: You are indeed able to verify that the file is from a certain author by looking at the certificate (with or without redirects). The reason why redirects are not an issue is because it does not matter if you download the file from a malicious website, as long as the file is digitally signed and the digital signature show that it has been published by the expected author, it means that the file is good (this is the whole point of a modern file digital signatures). Your comment about keeping your computer virus protection up to date is obviously valid, but having a digital signature that can prove the file comes from a trusted source is far more valuable and effective (IMHO).

Finally, all the concerns about private keys vulnerability (lost keys, mismanaged keys, stolen keys, etc) are valid but not realistic in most scenarios that matter. For a careless small time teenager digitally signing files from his or her garage computer this may an issue, but reputable corporations don’t take security lightly, you will have a very, very hard time getting anywhere near those certificates, and even if for some reason you were able to steal the digital signature certificates you would still not be able to use them because they are typically locked down with a strong password and they can be revoked at any time. I should also mentioned that if this was a big issue you should be shaking in your boots as we speak because all your banking transactions and online purchases (at one point or another) involve using the same technology used in digital signatures (asymmetric cryptography).

But do you know what the best part of a digital signature is? That if someone does not give a crap about them they can completely ignore them and move on with their lives. But for those of us who care, it is a very valuable feature.

Cheers.

Thanks for your explanation of file signing, this was my general belief too.

You raise a side issue, the availability of files.
Siglent's files are now freely available, no need for them to be hosted by others, so if Siglent's repository is secure any risk is reduced although not eliminated.

We understand signing is the norm in the western world, and I'm quite sure Siglent is considering their response as we type.

Here in the western world no financial entity would in fact place their security for transactions in a signed digital file. Security for those types of transactions are handled by encryption and secure end to end connection from client to server. I can understand his searching the internet for facts but just like a commerical here in the USA. No one is allowed to publish anything on the Internet unless its true. Google that you gind that to be true. Again digital signatures are a deterent only and by US law they cannot be used for any legal transaction. Exception of corp to corp.

Repeat after me, Digital Signatures Are Used For Authentication Purposes!

Are you aware that you can edit the windows registry to tell it to ignore cert errors! Then load a patch program so you access the file change it.

Yes, you are right, once you have set the language and set 'poweron' to 'last', the language will be remembered. so just ignore the language selection while you boot up next time.
This doesn't work on my SDG1025, however it's a trivial issue to me.

Now the interesting thing with the new firmware is the ability to upgrade with a license key. Any news on this? Where would one obtain a key and what sort of price? Online keygen direct from Siglen, or going through old fashioned mail order resellers for a piece of paper?

Would hardware upgrades be required? IIRC the lower spec SDG1000 series don't come with a fan for example.

IMHO Rene is just kicking up dust.
I agree with Docholiday: Keep the anti malware & virussoftware on your PC up to date and look where you download files from.

There is no way to ensure that even a signed file is really from the author if you don't check where you download it from. If you have malware on your PC which redirects a web request to a different server (this is really easy to do even with secure connections!) then you'll happily download a signed file from a malicious source.

I meant to post this earlier but I got lazy. Nevertheless, I wanted to address your post to help clarify some of your misconceptions.

But do you know what the best part of a digital signature is? That if someone does not give a crap about them they can completely ignore them and move on with their lives. But for those of us who care, it is a very valuable feature.

Cheers.
Well, don't take my word for it:
https://nakedsecurity.sophos.com/2010/06/23/trojbhoqp-verisign/

Conclusion from the article:
But regardless of the would-be victims, this technique, in addition to the fraudulent SSL certificate abuse we have already seen, serves as another reminder that the mere pressence of a digital signature does not mean that something is legitimate.

If you read the article closely you'll see that the malware actually looks to be 'more genuine' than the original software!

Doesn't work on mine either, that's the cause for my complaint.  I know you can just hit any button or twist the knob and this screen goes away but it shouldn't be there in the first place.  Like I said, an annoyance but I really like the generator and I couldn't beat the price.

I think we all agree that no security feature is perfect. The idea here is that a digital signature is great value added that is welcomed by many (there are no harmful side effects).

I am no security expert, I am simply an observer. I see all major corporations (Microsoft, Google, Apple, Oracle, Amazon etc) digitally singing every file they distribute. I am pretty sure that such major corporations do that for a reason since they have all kind of security experts pushing the issue and they wouldn’t be wasting valuable resource if digitally signing files was a pointless endeavor.

I think is about time we stop debating this topic here, I am convinced that Siglent has very bright and capable employees capable of making an educated decisions on what to do. Let’s wait and let them decide how they will move forward.

Thanks.

In my experience a .cfg file has only been included when needed.
Those that I have encountered have modified the startup splash screen.

You should be safe to upgrade without it, but if you wait a day or so we can get Siglent to confirm it is not needed for this update.

In the meanwhile I'll update one I have in stock to check for you and report back.

Edit
There was NO problem with this update and it seems not to need a cfg file as explained above.

Hi.

My friend got a problem with his SDS1072CML during firmware update, after restart all leds on and no life signs...
I read dump from S29F064 flash from my oscilloscope for him, but anyway same, looks a problem is that my board is CA_M_101000 and his one is CA_M_110300, looks they are not compatible :(

Maybe somebody has dump of S29F064 chip for 110300 board?

You have SDS????CNL and with ancient crap FW version P13 and dumped its flash and moved it to SDS1072CML and then you wonder because equipment is "dead".

More strange is that current FW version numbers (for both, CNL and CML) are  5.01.02.29  (not 22 and not 13) so I wonder what is going on here.  And inside flash memory these FW are really different even with same displayed version numbers (due to differencies in HW)

I saw CML oscilloscope with 101000 board(atten 1062CNL, but flashed with siglent firmware as boards are same). That's why I decided to offer my friend to flash his 110300 board with dump from mine, as it allready was dead and nothing to loose.  About versions - yes, 29 is last one, mine one I flashed 1 year before and 13 was the most common board for my board (and it works fine ) and 22 was the most last version before 29 was released. Don't know why friend choosed it to flash.
So the question is if somebody have a full dump of 110300 board flash ? I will be very thank for dump as really want to help my friend with that problem.  Or maybe Siglent specialist can sell flash chip with correct firmware in it ?
Or at last maybe he can sell whole board (110300) ?

I do not know if this is same bug because I do not exactly understand this quoted text.

But.

I have regognized one issue (least in last .29  Siglent FW for CML models.

If signal have fast enough high edge, no problem.
But if signal is example sine wave and if LongMemory selected and if timebase is more slow than 100us/s there is very bad trigger positiuon/jitter problem. I have not seen this never before.
If example I set 250us/div and example 1kHz sinewave p-p 6 division. Trigger edge, rising and middle of signal vertical level. Trigger looks ok if normal memory. Trigger fails if LongMemory. If I change signal to square wave. Normal memory and LongMemory and all is ok.
If I select what ever signal where rising edge is slow, example ramp or sine etc Trigger fails with LongMemory but works with Normal memory.
100us/div or faster it works normally with all settings and signals.

What happend with trigger stability iand position in new FW with slower than 100us/div specially if Long Memory selected?

I hope Siglent do immediately FW repair patch for this trigger issue what is really fatal class bug. (and do also something for this language select pop up in every startup)  Do it so that if power up with what ever one front panel button down it start from real factory new state including language select pop-up window. More deep default than it do with default button what still leave some user selections untouched)

How popular is Sigrok? It shouldn't be hard to create support for a particular instrument and yet only few instruments are supported.

I haven't seen any numbers on the user count. To be honest I don't use it much but have done some CAN decoding and it works just fine for that. For me the interesting bits are the protocol decoders but it has real potential overall.

http://sigrok.org/wiki/Protocol_decoders (http://sigrok.org/wiki/Protocol_decoders)

I'm certain it's used much more than people think. If you consider only the protocol decoding. These are things you pay real money for. If you are bidding / evaluating a job being able to use a free version of a particular protocol (like CAN) is a great benefit.

How can our products be supported by sigrok? we are not familier with this organization.


They are an Open Source project and even have an IRC chat ( #sigrok at irc.freenode.net). You can contact their developers and contribute patches or even be contributors, this last one would be positive for both your company and them.

It's not a formal organization, check their website.

I'd like to thanks Siglent that they solved the WAVEFORM command in LONGMEM mode on SDS1102CML
Unforunately there is stil a big problem

Because there is only one (DOCUMENTED !) command for download the data from the scope:
      WAVEFORM? or WF? (the short format).
The channel is selected by C1: or C2: prefix.
The optional parameters are DESC, TEXT, TIME, DAT1, DAT2, ALL
ALL is the default.
Example:
C1:WF? ALL
This mean you want to download the data from channel 1; the Template(DESC) plus the data.
If you initiate the above command like this you will get the data but you can't know when the trigger was.
So, for a normal download you must use some extra commands before the WF?
ARM;WAIT;C1:WF?
or
*TRG;WAIT;C1:WF?
Siglent say the ARM and *TRG is the same.
The WAIT command means the scope will wait until a trigger apears.
If you use WAIT 2.5 for example the scope will wait for two and a half seconds for the trigger.
If it does not apear in this interval the scope will enter in the acquire sequnce (forced trigger).
So far so good.
But what is if you want to download the data from both channels?
You will use of course ARM;WAIT;C1:WF? for channel 1
And C2:WF? for the second channel.
You can't use ARM;WAIT;C1:WF?;C2:WF? because the two WF? commands can't use the same buffer.
The big problem is that the firmware can't anticipate what would you do after the first WF? command.
So after the C1:WF? ends the scope exit from ARM state and begin a new acquizition on both channels.
When you initiate the C2:WF? command you will got some random data from channel 2.
In my opinion the the best soulution is to implement a new command which inform the firmware that you
want to download the data from both channels after an UNIQUE trigger.
Important remark!!!!
I'v used ARM;WAIT;STOP;C1:WF?
         C2:WF?;RUN
The STOP was for stop the acquizition after the trigger.
This is a stupid solution because you will get only a few bytes after the trigger.

I'd like to ask Siglent to solve this problem in a new firmware version

At last I have one question
Can Siglent document WFSU TYPE,1 command (WAVEFORM_SETUP)
I saw that this command is used by EasyScopeX

Did you contact with the Sigrok project? They're waiting a reply from your company, but no response since some time ago. If you're interested, you could contact over IRC at #sigrok on irc.freenode.net or check their email on their website.


I'm not going to annoy you with this, but you showed interest about your products getting Sigrok support.

PS: I'm not part of Sigrok development team.

Hi Siglent,

Would it be possible to increase the display update rate of the SDM3055, or give users the option to do it? Currently, there isn't much difference in "slow", "middle", or "fast". The data sheet states that the options sample at 5, 50, or 150 times per second. This is useful if logging and viewing the file after. Also, since middle and fast drop a digit of resolution, they seem to auto range and display a new value faster. But, the display update rate doesn't seem to change much, if at all. So while the log of values might allow you to see fast changing values, you can't see them in real time. The display, even on fast mode, seems to update 1 time per second, even though it has captured 150 values. I think it should be possible to update the display at 10 times per second for example, and average 15 captured readings into 1. Therefore, you get 1 average of 15 readings every 100ms on the display, and 150 captures averaged into 10 readings every second.

I have attached a csv (unzip with 7z or alternative, windows doesn't work for some reason) file showing the power of 150 samples/s. I programmed my DP832 to sweep from 0v to 2v in 2000 steps. The DP832 seems to be able to change 100 steps (100millivolts) in 1 second, so the meter sometimes captures the same value twice since it samples at 150/s. Why waste the speed of the ADC by limiting the display update? If you want a more stable reading, then you will use the "slow" mode by default anyway since it gives you the full 5 and 1/2 digits. You can also do something creative with the "middle" option, like give it 5 screen updates per second. Currently it's kind of useless, since it's slower than the "fast" option, but still loses a digit of resolution.

Regarding the problem that the meter doesn't save the UI settings on reboot, I looked into the xml file that you can create to save settings. Even when setting the meter to boot to "last", the xml file still shows "factory default" in the power up field. Maybe the power on "last" feature does work correctly, but the meter just doesn't set the parameter correctly. I tried editing the xml file by putting "last" in the field and recalling it in the meter but it didn't do anything. I also can't copy the edited file to the internal storage since the built in file manager doesn't allow it. I also tried recalling the edited file, and creating a new one in internal storage with the settings, but that didn't solve the issue either.

Seriously, I don't understand why you keep on at this. Sigrok is open source so the community can write code for it. Siglent have done all that is needed to enable this - they have published the SCPI protocol and even have LabVIEW drivers which can easily be examined with a trial version of LabVIEW - it's all out in the open.

Anyone can now make a Sigrok driver. Just find the code for another function gen in Sigrok that has been implemented using SCPI and modify it to suit. Surely it's that easy?  :-//

Why not give it a go?

Sigrok developers use their free time to maintain the project, they aren't paid for it.

They don't care about their product enough to submit a patch. That makes their products not attractive at all and just keeps perpetuate the "chinese products are crap" stereotype. Why do others need to work for them? Sigrok adds value to their products.

I prefer to buy products with companies friendly to my OS and Open Source, not needing reverse engineering or extra efforts. That's why I agree on "Fuck you, Nvidia".

Sigrok needs more developers, they are currently too busy and lack of sponsorship. They are tired of lazy manufacturers with kind words and zero support.

I'm not a developer, just an electronics student.

Can you please show me the other manufacturers who are writing drivers for Sigrok? Specifically the function generators. After all you obviously think the Siglent SDG is chinese crap and have another model in mind, say Agilent, Rhode & Schwarz or something pretending to be none chinese. Can you show me the Sigrok drivers they have developed?

From what I can see the Siglent is one of the two function gens that the Sigrok team are planning to support, the other being a Hantek. They can do this precisely because there is no need to reverse engineer the SDG or proprietary Windows drivers. It's all out in the open. You can switch your SDG into USB-TMC mode, linux includes usbtmc in the kernel.

Now, my Hantek MSO5102D oscilloscope on the other hand - that is crappy closed source proprietary shite. Thankfully due to the sterling efforts of tinhead the reverse engineering has been done - and most of the details are there for someone to pick up the can and add the layer needed for Sigrok. There is a case for this as the MSO has a logic analyzer in it which badly needs a PC front end as the one on the scope is crap.

You say you are not a developer, so what do you plan to do with Sigrok when you have this driver? As far as I am aware the only front-end available for it is PulseView for logic analyzers. A universal function generator front end needs to be developed too.

I consider 99.9999% electronics products to be crap in too many aspects. Propietary protocols, no hackability (I want be able to modify the hardware and software in ALL aspects, no walled gardens), bad quality, overpriced, difficulties repairing them and tons of more issues.

Because others ignore us, we consider specs good enough. But that's not sustainable in the FOSS ecosystem. That lack of community involvement from the interested parties is the reason projects get half-baked because no enough feedback and finally die.

Siglent attitude is hypocritically polite. They showed fake interest in the project and said to participate this forum, but they vanished and ignored us. They lost their credibility with that lack of seriousness, showing no responsibility nor compromise.

Do they want advertising? Pay for it. If they want to really get community involved, demonstrate it!

Yes, there's too much pending work in Open Source electronics tools. Even EdaCore looked very promising, but the project got very stalled and not sure about EvanFoss motivation.

Absolute  :bullshit:
If you wamt a scrap, you are heading in the right direction.   :box:

You must have blinkers on or are very one eyed.  :palm:

Have a look at their website to see the regular EE shows they participate in all over the world.
Siglent pay for advertising on the EEVblog main site and have done so for years.
You obviously have had little to do with the Chinese so wouldn't know how polite and humble people they are.
They were recently asked for product support in Labview and now their products are.  :-+
The fact that both Siglent and Siglent America are on this forum regularly must have escaped you, check their profiles for last time on line if you don't believe me.
I have no idea if Siglent is investigating Sigrock , but if they are, you won't know until support is announced. Jade (Siglent) is only one person in a team that has to take on suggestions and deliver them to the team for consideration and development. This takes real time, do you think Sigrock is the ONLY thing they have to consider.
Remember China is a very different culture and while English in a compulsory language for the young it is not used in mainstream employment, so there is hesitance in its use in a WW forum.

So pull your head in, breathe through your nose and have some  :popcorn:

Hello, I am new to this forum, and pretty new to blogs in general, so please forgive my ignorance.  I am a retired engineer (mostly Visual Basic software for Test Equipment), and I am thinking of playing around with some embedded processors, single board computers, and such as a hobby.  I have been looking for an entry level oscilloscope, which is how I found this forum.  The amount of information here is overwhelming, but much appreciated.  I have gathered that Rigol scopes have a strong following, but my rather uneducated preferences have been leading me towards a 2 channel Siglent scope, i.e. SDS1072CML (~$300 USD).  I like the larger display, the individual vertical channel controls, and the quiet fan. 

In this thread, I saw a link to a firmware version of 5.01.02.29, but I found on the Siglent site that they have a 5.01.02.32 version.  Can anyone tell me what features this firmware adds, or problems it solves?

I would really be interested in people who have had a Siglent SDS1xxxCML scope for a while to see if you are still happy with it?

Thanks so much for any help!

As far as I know it will have been only minor tweaks of functionality, these are a goood basic sound DSO and although only 2 channel, they do have individual vertical controls for each and 400V volt rated inputs, 2 important features the Rigols do not have.
The HW in this series is common up to the 150 MHz model, so there will be no frequency roll off in the 70 MHz model at max BW.

...The HW in this series is common up to the 150 MHz model, so there will be no frequency roll off in the 70 MHz model at max BW.

So, if I understand what you are saying, the difference between this model, and say the SDS1102CML is just the firmware?  Does that mean that the hardware's bandwidth is the same on all the scopes in this series, but maybe just the timebase settings are restricted?

Exactly.

Note the BW update option, this implies Siglent will be offering BW upgrades for purchase at some time in the future. I do not have this information officially, but due to the fact BW upgrade functionality is being added across Siglent's models/ranges one strongly presumes it will be the case.

Issue with the SHS800 Series Portable Oscilloscope's DMM 'Continuity' Measurement function:
The SHS800 Series DMM function 'Continuity' test has over a 1 second delay sounding the continuity test Tone when connecting to a closed circuit (a direct connection).  And there is a equal delay for it to mute the Tone after removing the test leads from the circuit under test.  Worst yet, the Tone does not sound continuously, but beeps On and Off while connected to a closed circuit.  All this makes it very difficult to check continuity, and impossible to locate an intermittent connections.  It is Ok to have a delay of the displayed Ohms value on the LCD, but certainly NOT with the Continuity Tone.   :-//
I have a SHS810 with the latest hardware and firmware, and I reported this issue to Siglent America.

Edit: The SHS800 and SHS1000 Series both currently use the same Firmware, therefore the DMM Continuity issue is most likely also in the SHS1000 Portable Oscilloscope.

Can someone explain the maximum input voltage specifications for the sds1000cml range?
It is quoted as "400V (DC+AC PK-PK,1M? input impedance, X10),CAT I" in Siglent's documentation.

Does that mean that it's the maximum when using a 10x probe?  If so what is the significance of 1M??  The front panel is marked 400 V with no reference to the use of a 10x probe and is also marked CAT II as opposed to CAT I.  All rather contradictory, CAT II on the front panel implies that it can be directly connected to measure the domestic mains supply - not that I have any intention to do that but it would be nice to know.

How about the maximum input voltage on the Trigger input?

1 M Ohm is the standard input impedence for oscilloscope vertical channels.

Normal scope usage is with 10:1 probes, up to voltages specified as max for the probe in 10:1 setting.
For SDS1102CML probes this is 600V.
Refer to the probe datasheet for the "derating with frequency" graph

Within a measurement system it is best to apply the lowest of any CAT ratings.

For ongoing HV work one is wise to have 100:1 probes for safety of yourself and equipment.

Sorry, I don't have trigger ratings at hand at the moment.

Thanks for your reply Tautech.

I designed and built my first oscilloscope while I was still at school nearly 55 years ago and have used them professionally over many years.  Now, in my retirement, I just play but I decided it was time to modernise my workshop a bit and have ordered an SDS1072CML from Amazon.  I just like to know the correct maximum ratings of any instrument I use.

I downloaded the user manual from Siglent and find it inconsistent.

1 M Ohm is the standard input impedence for oscilloscope vertical channels.
Of course, as it has been for decades but not relevant to the maximum input voltage spec.

Yes, although I do also tend to connect to the inputs with through terminations for video and RF use.

But what is the CAT rating?  The instrument itself is marked with one rating and the manual text quotes another! Perhaps a Siglent rep can give a definitive answer?

The manual is very poorly written (although much better than I could do in Chinese) but matters concerning safety of both the instrument and the user should be clear and consistent.

I have just received an email from Siglent.uk and they confirm that the 400 V maximum is when using a 10x probe.  The maximum input at the socket is 40 V, not the 400 V that is marked on the instrument.

They also confirmed that the 10x probe can safely be connected to the supply mains.

This is QUITE incorrect.  |O 

RTFM.

Siglent DSO's all have 400V rated channel inputs.
The standard probe with your scope is rated to 600V at 10:1 setting, with frequency derating to be applied of course. The derating graph is in the probe packet, use it.

So with 400v applied to the 10:1 probe there will be 40V imposed on the DSO channel input. It is in simple terms a 10:1 resistive divider.

Best advice for ongoing HV measurements is to have 100:1 probes so as to not push the voltage safety limits of 10:1 probes and thus provide additional operator safety.

What?  :wtf:

Perhaps he/she was billing office worker or secretary.

Yes there is in specs something what match 40V  it is maximum Offset voltage setting...

Input = Oscilloscope front panel BNC. It is oscilloscope input, also in China.

400Vpeak CATII   (???)
It is printed in Service manual. 

I hope in future Siglent take this seriously and use standards perfectly and tell specifications exactly so that peoples do not need try quessing.

Yes 400V is with a 10X probe!
We do recommend when you use this scope and you are testing equipment with a higher voltage then 40V to always set your scope and probe in the 10X setting. This is much safer!

Connection to mains or other high voltages can be done in the 10X setting but be aware the the scope has no isolated inputs!
The work safely with mains we recommend a isolated front end :

Hi Siglent,

in the other thread, https://www.eevblog.com/forum/testgear/siglent-spd3303d-series-bug/msg581704/#msg581704 (https://www.eevblog.com/forum/testgear/siglent-spd3303d-series-bug/msg581704/#msg581704) , I've described the problem I have with my SPD3303S power supply. Apparently, they've silently revised the board, rotating the LCD 180 degrees and after I've upgraded my (presumably older version) hardware with the latest firmware posted on the Siglent website, everything displays upside down. There's no mention on the website that it's only applicable to some of the SPD3303Ss. I got in touch with Siglent but all they could offer was the firmware version even older than what I had before: 1.01.01.01.03 vs. 1.01.01.01.03R1. That's a really weird situation, please help me solve that.

Did this get resolved? As I am having the same problem too.

Hi,
Recently I upgraded my Siglent 1102CML with new firmware 5.01.02.32. The main reason was that for single mode I could not enable LongMemory depth. Even I enabled it before, once I pushed Single button it returned to normal mode immediately. Now this works fine. Unfortunately when I scale time base to about 5ms, capture a single shot and then scale to 2,5us the display shows vertical stripes. When scaling deeper it even gets worse. If I change display mode to dots instead of vectors  the display is correct to about 250ns. Then the waveform gets flat (GND).
Has anyone else encountered the same problem? Please check with your scopes.
It would be also nice if Siglent could investigate this issue. I can support with data logs/pictures, whatever is needed.
Regards

I noticed others really want this from the reviews on Siglent dealer sites and You Tube reviews also.  Is this possible to have ASCII support in the decoder option?  I mean its going to cost myself and others an additional $169 U.S. dollars for the decode\trigger option -  so it would really help to sell the optional package and also more scopes in turn by adding the ASCII values in the

It is a hardware and software change.  So contact the dealer you purchased your unit from for instructions. The dealer should be able to handle and process this for you. Siglent is responsible for this and therefor the Siglent's authorized dealer should take care of it for you.

Report your results back here so that everyone gets see how Siglent handles this issue and that they get their due credit, or criticism if there are problems.

I pointed Siglent tech support to this before Xmas and while there were no promises, R&D are looking at including ASCII support in future SDS1000X FW if possible.


I just got my scope, and well from what I have checked over for use; including updating to the latest firmware...   

In my opinion: 

It is a really great scope at the price/ to performance/ to capability. 

256 temperature (color) intensity graded display-  excellent screen, by the way :-+
50 ohm impedance mode
hardware based triggering
Eres and sequence recording
500 uV/Div ... Awesome features at $424 U.S. dollars on Amazon

no extra channels... well you can't expect everything at this price, but this is an excellent scope-
Siglent has a winning product- the SDS 1102X

Hello Mr Siglent :)

I just bought few days ago your SDM3055 multimeter from Batronix.com
I have a little issue. It seems to work like a charm but sometimes, the transformer make some 50Hz noise.
A first, I thought that it comes from the metallic housing which vibrates because of the transformer but it doesn't.
If I tilted the device on the side, I can clearly hear the noise coming from the transformer but it is a very metallic and loud noise that is not normal.

What can I do ?

Thank you

Posting my findings after having this meter for a day and returning it. Here are my general ramblings in no particular order.

To be fair, I'm a hobbyist and I've used a Fluke 175 for the past 10 years. I basically wanted a convenient bench meter that was easy to use and read. I'd never owned a bench multimeter and decided to try the Siglent because it looked great and I'd had great experience with my Rigol 'scope.

I did not like the way this meter "felt", if that makes sense. It's slow, so naturally having read all the threads on it, I downloaded the latest firmware which made it faster, but "faster" felt like it was overclocked instead of feeling more responsive. Even with the newer firmware a continuity check was not instantaneous and my overwhelming feeling after testing it for hours was that I just didn't trust it. Everything about it just felt cheap to me and for the price, I returned it and bought a used Fluke (though that's got its own issues).

It takes too long to boot. I know it's a linux box and that's cool, but that also annoyed me. Yes, I know it should sit for a while to stabilize so boot time shouldn't be a big deal, but my Fluke bench meter is instantly on.

The screen drove me nuts. It's not as beautiful as it is in the pics, and there was no way to adjust either the brightness or the contrast. If I'd have been able to get that pure black that's shown in the marketing pics I would have been a bit more enthusiastic. I love the screen on the Rigol 'scope, so that was my baseline.

The always-on blue power light is terrible.

For reference, I'm not really a gear snob, but I like what I like. I have a Rigol DS1054Z that I love and I have none of these complaints about it except for maybe the boot time.

I loved some of the advanced features like the trending screens and such, but I just couldn't get past the feeling that I'd spent a fair chunk of money on something that I wasn't happy with so I returned it.

Hint: if you are not after 5 digits or more precision but still want a bench meter then get a 4.5 digit VC8145 ! This meter has instant continuity and lots of other nice features.

Problem with Siglent SPD3303D.

I bought this power supply about a year ago and then got busy with work and other things so it just sat in the closet until a few days ago. I have some spare time so decided to build an internet connected Programmable DC Load. I am powering the circuit off of the fixed 5V channel CH3 and using channel 1 (CH1) as the source supply for the load. I have it set at 5V to limit the power through the circuit during initial tests since I haven't attached the components to a heatsink yet.

As soon as I start to draw current the CH1 supply voltage starts to drop. It appears drops off from 4.98V no load/open circuit to 4.85V at 300ma and to 4.78V at 1.2A. I tried both channels. The behavior is the same on both Channel 1 and Channel 2. I even tried running the channels in parallel - same behavior. The display on the SPD3303D reads 5.00V throughout the whole exercise, never wavers although the current reading changes.

I checked to see if there were cable losses - nope. I checked the banana plugs at the terminals for poor contact - nope. I checked the output voltage with three different meters - they all validate the findings. In each case, the display on the SPD3303D reads 5.00V.

Any suggestions? Any ideas from Siglent Tech Support? Hardware version is V1.2. Software version is 1.01.01.01.06R1.

Thanks

Dominick

4 7/8 digit surely? (80,000 count not 20,000 count like a 4 1/2)

Have you found a recalibration procedure for it yet?

There are only 2 potmeters on the board so if it is out of cal just turn them until the values are within spec. However the LM385 reference in the VC8145 has a typical aging of 20ppm in the first 1000 hours so I don't expect it to go out of spec any time soon.
Title: EasyWave P34 issues
Post by: billfernandez on January 23, 2016, 05:59:07 am
Greetings:  I just upgraded EasyWave on my Windows 7 PC from version P32 to P34.  Now when I run it I get an endless series of error alerts:  "An unsupported operation was attempted." 

Version P32 was working fine before I uninstalled it so that I could install P34.  Is it possible that P34 is only compatible with Windows 10?

ADDED JANUARY 24:

o I uninstalled P34, restarted my PC, re-installed P34:  same problem.

o I ininstalled P34, restarted my PC, re-installed P32 (that's pee-thirty-two): the problem went away.

Just for test, unistalled P32 (also cleaned all residues)  and installed P34 without any kind of problem.

System: Windows 7 Pro -64  SP1  with all current updates.

P34 wworks just as previous version exept there can select also SDG2000X (8pts-8Mpts)
Installed using: "For all users"

I have not tested connection with any SDG equipment but some free plaaying with it and done some hand draw and equation draw waveforms and stored as .csv.
Just works normally without any extra error messages.

Hi -

I have a question about my SDG1025. I have done the same mod discussed on this thread to add a TCXO. This is working fine, but I recently set up an external 10MHz reference, and want to use that instead. I had to set the output of my reference to about  10 dBm (2 Vpp into 50 ohm load / 4 Vpp into high impedance) in order to get the SDG1025 to recognize it, and I am concerned that the TCXO might be connected to the same signal as the external reference input.

Can you tell me if this is the case?

Thanks

Don't worry, the 10MHz input is not coupled to the TCXO.  You can keep feed the 10Mhz input all the time and switch between the internal (now TCXO) reference and the external one via the menu.

In case anyone else runs into this, there was some strange behavior where the SDG1025 menu would show that it was set on external ref, but it clearly was not. This went away with a firmware update. Everything is working now.

Title: New Siglent Plus models (Siglent DSO HW improvements)
Post by: tautech on May 31, 2016, 04:13:51 am
FYI

Siglent have been working on some improvements to their existing models:

The SDS1000DL and SDS1000CML series now have 800x600 displays AND LAN as standard.

For the SDS1000X series there has been addition of 16 channel MSO to the previously known S models with inbuilt AWG. These will now be known as SDS1000X+.
The SDS1000X ( no +) range without AWG and MSO will stay. (100 and 200 MHz)
Enabling software and 16 ch probe assembly will need to be purchased for units with the new MSO port in the Plus models.

Having today sold out of SDS1102CML DSO's I unpacked and booted one of the new Plus versions of these good little DSO's.

Surprisingly the updated 800 x 480 display resolution is immediately obvious as too was the lack of the much despised language selection dialogue.  :clap:
The colourful Siglent splash screen at boot has been replaced with the same as all the newer Siglent series, the black screen and Siglent logo.

With contact to Tech support I was sent new FW, (beta I think) the update process being exactly the same as previously however there was no need to reboot the DSO, it did it itself.  :)

With double the display resolution there have been a few subtle changes in the GUI, text finer but more crisp for both menus and OSD. Trace colours are now yellow and pink, blue has been omitted as it's normally used for channel 3 on 4 channel scopes, less confusing IMO.

See for yourself

(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=241944)

And yes, I already asked Siglent to consider making the All Measure box transparent in forthcoming FW for the SDS1000CML+.

Hi All...

The reason I'm here is about a scope I got my hands on and the only info I found about the part number on the PCB brought me here (see pic)...  It's a rebadged Siglent of sorts.  From what I can tell it's a SDS1102 family.  Problem is, it's semi-bricked:  previously someone tried to update the firmware and the display is not the same resolution as the firmware was written for (320X240 5.7" display trying to run 480X234 7").  Bummer is, only the left half of the displayed window appears on the screen!  Also, there is no waveform when I probe something - probe and source are fine...  Tried to "Auto", but then a message "No signal" comes up...

Can anyone please help me with the capabilities of the hardware and what firmware I should load and how?  Is there a firmware version around that drives 320X240?

The brand is AA Tech ADS-2102B and the screen splash on startup says "Atten ADS-1102CM"!!.  Can't find any AA Tech support on web.

Yes the 5.7" display is pre the current "L" models. (7" widescreen)

Has the PCB any unpopulated areas were bigger/more memory modules might be?
This can determine if it's 40 Kpts or 2 Mpts memory model.

I only have some old Atten 5" ADS1000 series FW on my PC that might be of help but it will too big to upload as an  attachment for you to grab so PM me if you need it with your email address.

Hi there,

I hope that Siglent is actually reading this forum thread, and hope the get some support for details in regards to SCPI programming of the remote control protocols of the SDS1000X(+) models.
The problem is, that the current document for remote control is based on the older SDS1000CML version and lags the newer AWG and LA functions of the X models.
Is there any information on how to access these functions from the remote control interface.

Kind regards,
Marchel.

Hi Marchel,

Have you taken a look at this programming guide?

Thanks for the reply. This is indeed a bit newer that the guide that I found on the Siglent web side, however This guide is still not up to date, and missing a lot of the newer functionality that the newer SDS1000X(+) are featured with. It mentions the newer SPO scopes but the AWG and Logic Analyzer remote control commands are completely missing. Are there any plans to document/expose these commands? I have tried some analisys from executing the EasyWave tool with the NI trace tool, and comparing it with the remote control guid of the signal gens from Siglent. But the actual commands send from the EasyWave tool are not the same as whats in these SDG guides. And trying some of these commands only crasshes the scope so no luck on that. By the way, love the scope.

Post by: marchelh on December 06, 2016, 05:34:16 pm
The reason why I want this information, is to add the SDS1000(X/CML/CNL/DL) series scopes and MSO's to the SigRok library and support Pulseview to display the traces. I currently don't have the Logic Analyzer module, but I hope I can afford is soon enough to start testing the functionality of the LA. The selection system is already working and I'm now busy doing the initialization and data acquisition. So any information regarding the programming interface of the Siglent SDS series is welcome.

This is indeed a bit newer that the guide that I found on the Siglent web side, however This guide is still not up to date, and missing a lot of the newer functionality that the newer SDS1000X(+) are featured with. It mentions the newer SPO scopes but the AWG and Logic Analyzer remote control commands are completely missing. Are there any plans to document/expose these commands? I have tried some analisys from executing the EasyWave tool with the NI trace tool, and comparing it with the remote control guid of the signal gens from Siglent. But the actual commands send from the EasyWave tool are not the same as whats in these SDG guides. And trying some of these commands only crasshes the scope so no luck on that. By the way, love the scope.
Are you using the EasyWave that's specifically for the SDS1kX+ and previous S series ?

Maybe you must use this version along with the Programming guides to get the results you seek.
Let us know if that fixes things for you.  ;)

Hi, I would like to ask a support question for my Siglent SDS1072CML Oscilloscope. It's working fine but there is one little annoying thing and that is that at every powerup the language question pops up. I have to confirm English every time. I did read somewhere that this can be fixed by loading a config file, if this is true can you provide me the config file for my model oscilloscope ? Attached you find the details of my oscilloscope.
Thanks !

Yes, I did. This showed me some of the functions are available in the scope but not documented in the guides. And what would really be useful are the possibilities to switch on and of waveforms and change the AWG waveform time bases. And that is not implemented in the EasyWave application. So A more complete remote control guide would be a must, and make the scope really usefull.

Marchel.

Good, you are using the latest FW.  :-+

Language selection at boot has been an enduring problem for Siglent to get right for users and we have requested several times for this to be solved.  :horse:

But there's a reason why it's still present: these scopes are often supplied in #'s to educational facilities where students have great fun in changing the language setting just before they leave the lab.
Of course then on next boot the language selection is there to easily fix this.

If you just ignore it and use ANY control or button, the language selection dialogue will immediately disappear and you can just continue to use the scope.
If you use this startup procedure you will quickly get used to ignoring the language selection.

We know this is not ideal but it works.
Fortunately the X series and the new CML+ models don't have this annoying small problem.

Hi there,

I hope that Siglent is actually reading this forum thread, and hope the get some support for details in regards to SCPI programming of the remote control protocols of the SDS1000X(+) models.
The problem is, that the current document for remote control is based on the older SDS1000CML version and lags the newer AWG and LA functions of the X models.
Is there any information on how to access these functions from the remote control interface.

Kind regards,
Marchel.

Thanks for your reply. I assume that with the plus model now available there wil be no more updates for my scope. As said, it not a big problemen but it looks like an easy fix in firmware. If anyone (educational purpose) wants the selection at boot they can choose not to apply the update.

I couldn't say.  :-//
The CML's and CNL's are still sold in China along with other models we don't see in Western markets. They've both been good units for a # of years so I wouldn't write off there's more FW to come however I think any further tweaks will be minor. I now only stock the Plus models as they have LAN and a higher res display for the same price as the older models like yours.

Hello!

I purchased the SDS1202CNL+ oscilloscope and I want to connect it to NI LabView 2016. The problem is that Measurement & Automation Explorer does not see this model neither by USB, nor by RS-232. In the oscilloscope system menu item "Back USB" there are only two options available: "Printer" and "Computer", but there is no option "USBTMC". There is no firmware update for this model at the Siglent website. Could you help me to resolve this problem, please.

Welcome to the forum.

Which drivers are you using ?
For Matlab there a list of them here:
http://www.siglentamerica.com/gjjrj.aspx?id=204&page=2 (http://www.siglentamerica.com/gjjrj.aspx?id=204&page=2)
But the CML+ version is not there.  :( For LAN support we'll need a dedicated version as the non + versions didn't have LAN. I'll ask at Siglent to find the solution for you.....maybe you can use the CML version I do not know.
When you set the rear USB to Computer this is the correct for your needs.

I have a second beta firmware for the CML+ but Siglent are still working on firmware for public release and we will announce it here when it's available.

It may be ~12 hrs before I get a reply from the factory.

it shoud be, because the cnl+ (no long mem) and cml+ (short and long mem) in "short mem" mode logicaly must be the same.
Unfortunately this upgrade is not compatible with the plan cnl or cml versions.
I'd like to ask SIGLENT if there is or it will be an other version above the 5.01.02.32, because this one is full of bugs in long mem mode

Thanks good to know, thank you.....risky and I wouldn't have tried or recommended it until we had confirmation from the factory.
I was thinking the same as illyesgeza and checked the old versions too, just to make sure.

Hello
Below are some screen shots. On the fourth you can see the problem.
The bug is related to a wrong setted delay for the PRETRIGGER and the settings of the POSTTRIGGER in
LONG MEM mode.
I ask anyone who have a SDS1102CML or SDS1102CML+ to reproduce my simple test and post  the result.
Here are the steps:
Set the DSO trigger option to NORMAL, the time base to 100us, the memory depth to NORMAL (short) and
1.)apply to channel one the 1kHz test signal from the DSO
on the screen will apare fig1.
2.) push the SINGLE button on the DSO; after a short time will apare fig2 (with the RUN/STOP button litting red)
3.) push again the SINGLE button and select the memory depth LongMem; now you will see fig3.
Untill this momemnt everything is ok
4.) Push the SINGLE button and it will apare fig4. or something else , more confuseing
On my fourth screenshot(fig4) it is obvious that in the PRETRIGGER zone (left to the middle of the screen) are to few good samples,
most of them are leftovers form a previus acquisition, or worse , some unknown memory content.
Once I got a WAVEFORM in wich were all the content of the DSO's flash memmory.
This problem is since i bought the DSO many years ago.
I'm not convinced about that the problem is solved in the newer DSOs.
That's why I ask to make the test on any CML or CML+
The bug is present on LECROY WAVEACE to.

Sounds very similar to what I get on the CML+ on Long Memory.

I allready told this problem to SIGLENT but the response is always the same, to use the latest firmware but that is for cml+ with larger screen, not suitable for plain cml
I hope that if somebody else than me will support my opinion about this bug in that case probable SIGLENT will solve the problem
Now the LONG MEM (2mega points) is useless

Your (hard to follow) 1 to 4 seems to work correctly as I would expect on the CML+.

Maybe related, AFAICT the CML+'s LongMemory only works fully on SINGLE. While running/READY it seems to be using only around 400K of the 2M memory, with a lower sample rate than displayed! (I know LM is 500MSa/s max.)
With the memory bar looking like the attached, I only have about X 2 contraction, on expansion I haven't got 100 samples/us either!
An expurt is needed to figure out how LongMemory works.
Title: Re: Siglent Technical Support join in EEVblog
Post by: illyesgeza on January 27, 2017, 12:06:06 pm
No one have to be an expert to know if you have 2Mega memory than you have to use it fully no matter with what kind of samplerate
I also understand if you have two sets of memory on the same hardware (like SIGLENT's CML series) it is hard to switch them.
But once you have decided to make such a device and you sell it saying that it has 2 Mega memory you can't tell that sorry it use only x mega.
I am not angry because  there is not used the entire address space, I am angry about that this fact is not documented.
In LongMem mode using the TEMPLATE structure you can't find where the trigger point is, nor at what address begin the trace and where is ending.
This problem is not a hardware problem. It is a software one since in shortmem(40k) everything is ok.
I have explained in detail to SIGLENT how I imagine to solve it. I sincerely hope that it will be solved

When I had a problem with my SSA unit, Siglent America was Johnny on the spot at getting me back on line. A dude named Rocco was exceptionally helpful and responded to my questions and concerns quickly.

For me, customer service is of major concern when selecting gear, and I have found Siglent America to be very responsive in pleasing the customer.

On a less positive note, I found the SSA user manual to be awful. It was something like, and this is not quoted from the manual but just to give you an idea.
The BW key is used for selecting bandwidth. This was not in the manual but was written that way to show how useless the manual is. In my opinion of course.

I recently purchased an SDS 1102X SPO and I am having problems connecting the oscilloscope to the PC through the 'USB Device (USBTMC)' connection port at the back of oscilloscope (below the LAN port).

The problem is that the PC "does not even see" a device connected through the USB. My OS is 'Windows 7 SP1' but I have tried it with a 'Windows 10' machine as well and run into the same issue. The firmware of the oscilloscope was up to date when I purchased it and I tried installing different versions (USB host works fine) of the firmware and repeat the same process and still having the same issue. I also tried with a different cable.

During the trials, I also do select the USB Device USBTMC option from I/O Set on the oscilloscope.

I recently purchased an SDS 1102X SPO and I am having problems connecting the oscilloscope to the PC through the 'USB Device (USBTMC)' connection port at the back of oscilloscope (below the LAN port).

The problem is that the PC "does not even see" a device connected through the USB. My OS is 'Windows 7 SP1' but I have tried it with a 'Windows 10' machine as well and run into the same issue. The firmware of the oscilloscope was up to date when I purchased it and I tried installing different versions (USB host works fine) of the firmware and repeat the same process and still having the same issue. I also tried with a different cable.

Your help is much appreciated, thank you.
Welcome to the forum.

For LAN and USB connectivity you need to install the NI VISA Runtime package, the instructions for which are in the EasyScope package on the CD. Within the NI package are dedicated drivers for each Siglent model.
Please find a small doc that I prepared to assist with problems like yours.
Let us know how you get on after studying the EasyScope instructions and the doc.

Thank you for your help. I get around this problem by connecting my scope through LAN, the USB, unfortunately, does not still work.

I am facing a problem when sending commands through EasyscopeX. The problem, I believe, is that the oscilloscope can not locate the root location for my USB disk.

When I try: DIR? DISK, UDSK
It returns: DIR DISK,UDSK,"A:

0 File(s), 0 DIR(s)
"

Likewise, when I try to store channel 1 to disk by: STO C1, UDSK
It fails and I can read "Cannot open file" on the oscilloscope screen as it fails to locate the usb drive.

Note that the USB disk is inserted, I can store images manually using the buttons on the oscilloscope but I cannot do it using the remote commands. The remote commands also work fine for some operations, eg. when I type: *IDN?, the scope succesfully returns: *IDN SIGLENT,SDS1102X,SDS1XDC4163536,1.1.2.13 R5. However, the ones related to "Mass Storage" do not work.

Yes, Windows will have used some other device driver NOT the one listed in the doc I linked.
You need get into the USB port properties and point Windows to the correct driver within the correct folder.

Hello!
I address to you with a problem.
Please help me, do not ignore my request.

I use the oscilloscope SDS1102CML + (Serial number: SDS10BA2162696).

Recently I found that on the website http://siglentamerica.com (http://siglentamerica.com) there was an update of the firmware for this oscilloscope.

I downloaded this firmware http://siglentamerica.com/gjjrj-xq.aspx?id=5074&tid=15 (http://siglentamerica.com/gjjrj-xq.aspx?id=5074&tid=15)

And now, after updating the firmware (from a flash drive, as written in the manual), the oscilloscope is not loaded. The Siglent logo appears and nothing happens.

In the document with the firmware file it is written that the first version was 6.01.01.08.
But in my device, the last digit of the firmware version was 13. The first digits, unfortunately, I did not remember.

I understand that I failed the oscilloscope. Maybe it was not worth it. I do not know what to do now.

Please help to revive the oscilloscope. I really hope for your help.

Sorry for my english, I'm using an translator.

Welcome to the forum.

1.18 is the first official FW update since the CML Plus was released. There have been others but they were Beta versions.

For your frozen boot do this.
After power on press the Math button quickly and repeatedly until the scope moves past the logo screen.
It may need more than 1 attempt.

Please inform us of the outcome.

Honestly, I tried to do it many times. Nothing happens. Once upon a time, there was a case that the oscilloscope hung in the measurement. I did this operation, as you advise and it worked. The program reset to factory settings.

But now it does not work. I'm afraid I ruined the firmware.

Yes, it is a little confusing but if you press the > (right) button the incorrect file warning disappears.

(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=303211)

You have correctly navigated to the firmware update file from within the UI, it's highlighted (selected) and now press "Load" (F4). Prompts after this point are self explanatory and the SHS will ask to be power cycled when the update is finished.

Firmware load failures mostly arise from power interruptions while updating but the for the SHS series you do have the inbuilt battery should there be a power failure.
Some use a UPS for power security while updating and that's a good safeguard but without one try to resist doing updates in stormy weather when power failures are more likely.

As a footnote the new 2R7 FW now works as expected in my SHS810.  :)

SHS806 On the old and new firmware equally.
1.Noise at inputs without signal
2.Delay between channels, the same signal at the inputs.
3-6.Interpolation sin? one picture with different time/div
7. No interference, which is not, 10kHz ??  :-//
Does Siglent have no engineer to see it?  |O
Let him pay me for testing their bad firmware.
This is not all, there are more than a dozen bugs.
 With such shortcomings SHS series of oscilloscopes should be generally forbidden. :--

SDM3055 and problems with temperature measurement.

SDM3055 fw: 1.01.01.16R2

For example, the dependence of the resistance measurement on a 2-wire circuit is plotted against time. Moments of switching ranges can be seen. (see R.png)

1. Switch to TEMP (PT100). Switching moments became very visible. The switching time is about ~700 ms. (see T.png)

2. When measuring the temperature using the PT100, the entire range is divided into two automatically selected sections: (-200.00 ... + 379.50) °C and (+266.34 ... + 850.00) °C. Nowhere is this moment reflected.

3. Each resistance measurement by the SCPI command blocks the operation of the temperature meter (PT100) by ~800 ms.
For example, such a cycle of commands will only record the change in resistance, the temperature will not change.

CONF:RES AUTO
READ?
CONF:TEMP RTD,PT100
READ?

After the end of the cycle, the temperature will start to change and be measured correctly only after ~50 measurements.

4. I would like to get a 4-wire temperature measurement for the PT100.

As another SHS806/1062 user i would like to add a few of the bugs i found.


- I agree with pantelei4 the probe settings (X10 X100) are ignored in Scope Trend Plot mode.

- The trend CSV files (both meter & scope trends) are not time/date stamped which makes it harder to plot and understand later.

- The filter turns off once the scope is triggered or if you press the Run/Stop button and then you have to go back to turn it on again.

- When saving a BMP image sometimes the waveforms would disappear from the screen for a second and the saved BMP image would have no waveforms in it.

- In inverted screen colours mode it is difficult to read the values when you select All Measurements in cursor measure mode (yellow text on a light green background).

- and the last one (maybe if someone else can test this on theirs) when measuring a 9V battery in meter trend mode moving the cursors around you can get the voltage to briefly drop to exactly 1.000mV.


I think there maybe a problem with EMC susceptibility as when using it on industrial control panels it seems to lock up or not save files properly. In these panels there can be thyristors and IGBT's switching heater banks and motors. I don't use it enough in that environment to be a 100% sure though.

Overall i like my Siglent SHS scopes but the firmware does seem to let them down. And before anyone asks i have sent emails to Siglent but i got told we are looking into it (2015 & 2016) so i gave up, maybe if everyone with a Siglent SHS scope adds there bugs to this list maybe something will be done.

I have the rebranding version of SHS810 for Russia named AKIP4125/2 since 2014. Plus to mentioned bugs I would like add my favorite pain - storage system. I wrote about https://www.eevblog.com/forum/testgear/siglent-shs810-saverecall-problem/msg706464/#msg706464 (https://www.eevblog.com/forum/testgear/siglent-shs810-saverecall-problem/msg706464/#msg706464)
Since 2016 Russian distributor of Siglent's devices don't sold AKIP4125/2 anymore and changed name to AKIP4125/2A.
I asked they which difference beetwen devices. They said - we don't know exactly, but specification the same.
I guess, Siglent fixed some bugs in hardware of SHS800 and new devices don't has old problems. ;)
I don't beleve that Siglent will  be do anything for repair old  version devices :(
I use some usefull properties of SHS810 for floating measurements and works in field and don't require more from it. Device's battery enouth for 3-4 hour of working.

My personal SHS810 has a 2013 production date and the latest firmware makes no distinction of when the unit was made. So use the new firmware in any SHS but unfortunately the new firmware apparently only improved the Continuity test response.  :(

So yes, we expect more improvements but they can be only as good as the quality of feedback to the engineers.

Are you saying the new firmware created all the issues you have reported and they were not there before ?
To get good results we must give good detailed feedback.

The same problems were with the old firmware.
2R7 version don't  any difference from 2R2.

The "bug" was actually just a slower-than-desired continuity beeper function. We made a hardware modification that also required the FW update and the difference is obvious. Units that have shipped in the last year or so have included this new HW. Upgrading an older design to the newer FW will have no effect on the instrument.

While you are at it pass them this one too with a footnote: "SDS1102X can't decode, thank you very much"
Initial feedback from the factory is at timebases slower than 10ms there is a problem that the engineers are looking at.

From the SDG2042X thread:
Hello zorromen,

We tried to post the answer here but we had three screen shots and it took up too much room.

We did find the problem. Please contact us at
info@siglent.com
and we will help you out on this.
Hence the need for a faster FW roll out of alternative and smaller file types for screenshots. (png etc)
These have been promised for a while and many of us have had quite enough of compressing imagery for online screenshots. Get a move on Siglent.
Further thoughts on the subject for other saved/printed file types for Siglent DSO's.

While default and only file type currently is BMP, the file size is large so that it takes some time to transfer to a USB stick and if any conversion to a smaller file type was to put additional load on the processor and add lag to the save file time it may be somewhat negated by the much smaller file and subsequent lesser transfer time.

Should there be some penalty of extended file processing time despite there being a smaller file to transfer I would be happy to pay that price for a much smaller and more manageable file size and type. Most users I suspect would be happy if there was some small delay price to pay.

Some new information on several Siglent products that I thought might be of interest:

  1) Open socket communication with Python        Application With Script

  2) Verify an open socket LAN connection using Telnet     Application Note

  3) Verify remote control connection using NI-MAX      Application Note

These can be found at
http://siglentamerica.com/prodcut-pxzl.aspx?id=5109&tid=1&T=2 (http://siglentamerica.com/prodcut-pxzl.aspx?id=5109&tid=1&T=2)


Also, new firmware for the SDS1000X/X+ oscilloscopes (V1.1.1.2.15E3) is located at
http://siglentamerica.com/gjjrj-xq.aspx?id=5270&tid=1 (http://siglentamerica.com/gjjrj-xq.aspx?id=5270&tid=1)

Finally, an update on open socket communications with Siglent products:
Open socket for the SSA3000X spectrum analyzer is currently supported in the latest firmware.
We have more on the way, including the new SDS1202X-E. I do not have a date on those yet. The SDM3045X, SDM3055, and SDM3065X DMMs are being tested now.

Attached captures of whats going on. Device is recognized in device manager, can send commands and get answers from the scope but when I try to open the virtual panel it hangs the scope forever, have to cycle power to get it to work again.
Any clue? Thanks.

@Siglent - feature request

Hi,

I recently bought an SSA3021x, very nice features vs price. There is a setting that turns on and off screen text, shows menu item selected and value. Instead of just on and off, it would be nice to have a mode where the menu item shows up when an entry is started and then goes away again after a delay ( settable ?, the entry should be cleared and aborted after the delay ) or accepted when the entry is completed ( selecting units or hitting enter ). Example, I like to leave text off, but when I go to enter say a frequency, it would be nice if what I'm entering would pop up on the screen then go away after a delay ( canceled ) or when the entry is completed.

@ Siglent America:
 I posted some of this blab on another post and thought I may get some answers here, seeing as I could not find Siglent Australia or Siglent UK on EEVblog     ;D


I recently updated the firmware on a Siglent SDS1000CFL 4 Channel series > Firmware Version: 5.01.02.38 | Released 2015-03-10
Software Version on updated unit: 5.03.02.38  Hardware Version: 15-f0-0.11

Result: the 'Siglent' brand boot time splash screen is now gone, replaced with a blank white screen, but it starts up ok,
and Channel 1 vertical gain issues I was concerned about (higher on default start up compared to lower but equal gain channels 2,3,4 ) are all gone,
and the scope appears to work as it should.

Besides an ocassional freeze in response to extreme control dial work (fixed by power off/on) the scope does the business as I expect, I think..  :-//

The firmware was direct from Siglent btw, and one must be VERY cautious to select the correct file on their support pages   

The firmware instructions I have attached to this comment don't tell you that much, the final step 'Part 2 Update Cfg' made no real sense to me nor responded, or perhaps not relevant to my scope model.

QUESTION to Siglent America: is it 'normal' after this update for the boot up screen to be WHITE and no Siglent logo or text etc ?

Thanks in advance, and your participation at EEVblog for Siglent customers to post their questions or concerns, is very much appreciated   :-+   :)

Your first call for support should be to your local seller or regional distributor:
TRIO Test & Measurement Pty Ltd, AU authorised distributors.

For our part of the world, (Oceanica) NZ and AU the factory is the best match of timezone for fast replies.
The rest of the world is best served by either US in Ohio or Hamburg Siglent branches.

How did you update config? This last update package do not have config file at all. 

There is long way from 5.01xxxx   to 5.03xxxx.  Perhaps there is some previous update what have included also config update file. I do not know but I feel that perhaps this version jump is too big and it need first do some intermediate update before this last version. I do not remember what all versions have included needed new cnf file. Perhaps before this last update it first need some previous version update, example: SDS1000CFL_4CH  Version: 5.03.02.12 | Published?2014-09-26. There is also new config for 5.03xxxx versions.

But, I do not know if you can now downgrade and update this previous version first before last version or do it now need some "trick".
I recommend to contact Siglent China Engineer who know what and how to do now. Best that do not try enything before get real information based to real knowledge. (Siglent Engineer) For avoid more problems.

Many thanks gents for the great feedback and helpful advice    :-+

it appears with all my experience and caution updating MANY firmwares on too many products over many years, this time it appears to be a part-FAIL   :--

The SDS1xxxCFL scope works but boots up like a prototype with white screen and no name

My brief tests have been limited to sig gen verification and to 10x cal the 4 probes to their respective channels

Yes I tried re-flashing, no difference
Yes, I tried it with 2 different USB sticks freshly formatted to Fat32
Yes, scope hooked up to a SmartUPS during procedure 
Yes, I tried -next welcome suggestion- too   :)

Either the wrong firmware was posted at whichever Siglent support site is the actual MAIN support site.   :-//  :-//
or it's similar firmware version to other models.

Unclear instructions, an obese 1mb BMP picture of text, and no proper text file   

NO CAUTION to update older firmware in steps, assuming that's the case here.
and whatever else described in my previous comments above


The user (paying customer who purchased Siglent instead of Rigol or Hantek) can't possibly be at any fault here and Siglent should sort this out for me DIRECTLY.

Why should I have to hassle the seller distributor when the manufacturer needs to get their support in better gear?

Updating a Siglent should not go south when it's the same SIMPLE routine as updating the firmware on a Pentax camera or a Dell or Acer PC,
companies that make their firmware files, and instructions to use them,  VERY CLEAR, including if it needs to be done in steps... 


I've had ONE (x1) bios update fail on a Dell PC and after one phone call explaining the update routine, Dell advised me it was a flaw with the motherboard revision and had a tech come over asap, who fitted a new motherboard AND updated the bios and did a diagnostic, while I watched  :popcorn: Good job too btw.

How can I not recommend Dell products to the average battler who wants advice on what 'all in one' PC package to buy  >  "I don't know what's around, just get a Dell.."

Now that you have let off some steam, some things that I might ask and others that might help you.

Where did you buy it, do they offer zero support ?

rf-loop and I frequent this forum to offer help to those that need it and we both have close contact with the factory to do so.
Bitch if you must but please understand not all Siglent branches of which there are only 3 are in your timezone and can always offer timely support. But we 2 can and the community of others that own and use Siglent products.


This might be a problem with the FW but as you see another user has no problems.
Right now you need to wait until next week for Trio to contact you, they ARE Siglent's rep for AU and the guys on the ground that will sort it for you. Special software may be the fix for your unit, this I am unsure of.

Yes, the instructions can be better and to help buyers not have problems updating FW both rf-loop and I only despatch units with latest FW installed.

Be patient, a solution will be offered.

Thank you sir, it wasn't a steam, well maybe it meandered toward the sauna room..   

A little disappointed at finally pulling the trigger on a first basic DSO, against my better judgement since I have analogue storage cros that still do the business for transient captures and the like etc, but 4 channels and one button single shot in a small box can come in handy sometimes

I wanted to avoid getting caught up in the DSO 'Daze Of Our Lives' dramas happening to others I read about here and Youtube,
and LOL here I am    :palm:

Yes, it was purchased locally from the authorized distributor interstate, but why hassle them for a manufacturer related issue that can be possibly resolved via the internet, with some simple button commands and a restore and update file routine or whatever ?

TBH: I still believe the Siglent is as good as the competition and chose wisely for my humble requirements,
so if I have to be patient for a positive outcome, it's not a problem.     :)

Feature Suggestions for the SDG-2000X:

1. allow a modulating wave shape (MDSP) for FSK so that a square wave signal can be uploaded to modulate an arbitrary bit sequence (example: "C1:MDWV FSK,MDSP, ARB")
2. allow the modulator to use the other channel as the signal source (example: "C2:MDWV PWM,MDSP, C1")

Right now the FSK modulation feature is rather limited.  One can only modulate a simple square wave or it requires using an external source.  It seems like an oversight not to allow an uploaded wave form to modulate the FSK signal.

Actually, this is something that we have started doing but we will remind those involved of the importance of it. Some product families have probably been better than others.
Thanks for the reminder.

@Electro Detective
How did you update config? This last update package do not have config file at all. 

There is long way from 5.01xxxx   to 5.03xxxx.  Perhaps there is some previous update what have included also config update file. I do not know but I feel that perhaps this version jump is too big and it need first do some intermediate update before this last version. I do not remember what all versions have included needed new cnf file. Perhaps before this last update it first need some previous version update, example: SDS1000CFL_4CH  Version: 5.03.02.12 | Published?2014-09-26. There is also new config for 5.03xxxx versions.

But, I do not know if you can now downgrade and update this previous version first before last version or do it now need some "trick".

Thanks for the very fast reply.

FWIW, the page at the following link would probably be a good place to post the guidance on which firmware versions can be updated from which other firmware versions: 

http://www.siglentamerica.com/prodcut-gjjrj.aspx?id=1364&tid=16&T=2 (http://www.siglentamerica.com/prodcut-gjjrj.aspx?id=1364&tid=16&T=2)

But when you click on HistoryVersion the page comes up saying:  Information not found!

If you download the latest firmware you get some release notes saying what was in each release but no guidance regarding what versions can be updated from what previous versions.

Both the download page (at the link above) and the download itself should advise a user if there is a need for interim version updates.

Also, since .cfg files are sometimes required and sometimes not, the notion of whether a .cfg file is required or not should be explicit, ie, the notes should either say "a .cfg file is REQUIRED with this update" or say "a .cfg file is NOT REQUIRED with this update" (rather than "If a CFG file is not included with a firmware update then it will not be required for that update").

And for completeness, perhaps a note should be included saying whether downgrades to earlier versions are allowed, and under what conditions (from what versions to what versions).

PS, while it would be great to fix up the documentation asap, it's probably a higher priority to help MrW0lf at the link below get his SDG2042X restarted (I wouldn't want this post to get ahead of his request for help).  EF

Stay tuned!?  to what frequency?   :-//

instead of making Siglent fans drool over new models and "website upgrades and we planning for improvements"  I suggest it's GOOD/BETTER/BEST BUSINESS practice you make it a top priority to sort out this FIRMWARE FIASCO immediately for your customers who digged DEEP in their pockets and went for Siglent products rather than the competing Rigol and Hanteks etc,

and to relieve the pressure off your concerned loyal hard working distributors and dealers, doing unpaid hard time on EEVblog currently acting as excuse buffers, for Siglent's firmware packages scattered at random on Siglent support pages, with questionable performance and poor documentation. 

Packages enclosed in RAR files which should also be offered as bog standard zip files as well. 

PLEASE CONSIDER !!!  :-+

What it implies and should mean, is if they did their update file homework properly, the current 'FW upgrade' should bring the unit's firmware version to the latest revision, regardless of the version currently on the unit.

and if this is not the case (and who really knows ATM) and it needs to be done in consecutive firmware update steps, then it is the manufacturer's RESPONSIBILITY to inform the end user of the correct sequence, to avoid either bricking the unit or introducing erratic performance, which in turn breaks balls for everyone, including the dealer distributor who has to play unpaid gas negotiator.

This is kiddie stuff, it shouldn't be happening at this level of product manufacture and release in 2017    :palm:

FWIW, the most recent SDG2000X firmware upgrade comes in a .rar file.  When you unpack that file it gives you a file that is the actual .ads update file (with no .cfg file for this particular update), and it gives you a "Firmware Revise History & Update Instructions" .pdf file.  In the .pdf file is a chronological listing of the updates with file name and date, and for each file is a list of the features or bugs addressed including descriptions of the features or bug fixes.  However, there is no mention of what updates can be applied with or without previous updates.  To be clear, listing the firmware updates in order of release is not the same as specifying which updates can be applied regardless of previous firmware status and which updates require one or more interim updates.  This might not seem like a big distinction, but for a user bricking an update the experience becomes a frustrating loss of time in trying to correct the problem along with a loss of the productive use of the product, and for Siglent and it's distributors it only adds work and cost while potentially jeopardizing future sales.

Siglent, I think what users are saying is that while it is impressive that rf-loop and tautech and others are offering their best possible assistance to Siglent users and potential Siglent users around the world, it would be helpful if the firmware updates had better documentation. 

As Electro Detective (no relationship to Electro Fan, whatsoever) has said:  it is the manufacturer's RESPONSIBILITY to inform the end user of the correct sequence, to avoid either bricking the unit or introducing erratic performance.

FWIW, I've just made the decision to purchase a SDG2042X so I don't have any experience yet with the product, but in looking ahead to possibly having to update the firmware in a unit that has possibly been sitting in a distributor's inventory for awhile, I think there is room for improvement in how firmware updates are documented.  The good news as I see it is that 1) the SDG2K is capable of offering very good features and performance and 2) it looks like Siglent has been providing firmware updates about every 3-6 months.  So why not capitalize on all the good work that has gone into designing, manufacturing, distributing, and supporting this product (and other Siglent products) by improving the documentation (for both the product manuals and the updates)?

Cfg files are only offered when considerable change to the OS/UI are needed in units and when this happens (rarely) the FW install instructions are quite clear as to the procedure that MUST be followed for all the intended changes to take place.
TBH I've never had an update fail and I've done hundreds to many many models.

Thank you.
Please understand it was only a couple of years back we did not have FW changelogs and after much nagging by us and customers most changes are now documented.
This can still be improved some, Siglent are still learning their trade in this respect and comments in the changelog like: Fixed some bugs are not entirely helpful.

Yes.

Why these things happen I am at a loss to understand, the only suggestion I can offer is to return all units to factory default before installing updates.
This is not documented but as I have zero problems with new equipment FW upgrades before they are dispatched I wonder if this may be the issue.
Before you say Siglent needed to have checked the FW before release, think about this; how many user setups and control conditions would need to be individually checked before guaranteeing no problems will exist after updating the FW ?
I intend to explore this with tech support and maybe have some instruction in future FW to say: return to factory default before updating.

There is certainly the possibility a new unit may come with older FW especially if it's been in stock for a while.
OTOH, all units that I've received for probably the last 6 months have had the latest FW already installed and this saves me a lot of time but I still check every unit.

The owners of these units also deserve great thanks for the contribution of ideas and improvements that have been subsequently incorporated over some time. Not all these have been documented in previous user manuals and for those that haven't spotted it there's a new User manual for SDG2kX released just a few days ago.

If the device's configuration can cause the update process to fail, then the firmware update mechanism should must restore the factory defaults at the very beginning of the upgrade process, and the firmware update instructions should make it clear that this is what will happen.  Obviously, then, the unit should provide a way to save and restore the unit's configuration, and it should do it in such a way as to make it difficult for the firmware to improperly set things up after the upgrade (the easiest way to ensure this is to use a text file to represent the configuration, which will force the firmware to parse the configuration file so that, at least, you don't wind up with otherwise-impossible settings resulting from some binary file mixup like you easily could if the settings file were just a memory dump or something).

Excellent points and clarification from the gents comments above  :-+

Speaking strictly for myself: I'm more than willing to blow out ALL existing user setups and control conditions and whatever, reboot the unit a couple of times,
to give it a fighting chance to revert to Day 1 firmware, and then apply the update, or updates in sequence, whatever the case may be.

This has always worked for me with digital devices, including computers, phones, cameras etc etc 

I do not expect the manufacturer and their software staff stressing with extra 'what if we do this?' code, to try to save user preferences on a vital software/firmware update, when it's far more important to have the DSO in an updated refined usable state,  scrubbing EVERYTHING in the process.  :clap:

Tough titties on lost user presets and setups   :'(   :'(  , just do them again,
you would have to anyway on a new unit or if the current DSO got fried or stolen,
or work colleague or boss screwed with your settings (people that deserve a long 'time out' on a well used kitty litter)

Thanks but I'm in no hurry, as I know the coming ordeal is going to be a long haul,  |O
explaining, documenting, sending off the unit, getting it back worse than when it left or unchanged,
neanderthal couriers trashing it and the blame game that follows,
the endless emails back and forth, waiting for responses from Siglent, etc etc etc
NO THANKS !!!

It probably needs a firmware nuke back to Day 1, and the correct file/s and instructions to do it properly.

I am convinced the files posted at Siglent were not specific as to WHICH CFL series the firmwares belonged to.

The support site is confusing and could use a coding nuke too and proper update. Hire someone that knows what they are doing, not clueless relatives, friends or whoever works cheap.

It's my first and last DSO, I've put back an honest analogue storage cro back in it's place on the bench. I need to get work done.   

Buggy or half@$$ed firmware DSOs are officially an expensive bookend at best for me.
If I don't need to see 4 audio sine waves at once or capture a 10hz distorted pulse, it can stay in the box
or hit Ebay with full 'selling because...' disclosure for the bidders.

The DSO novelty is GONE for me, I can live without pretty trace colours, wide screen, USB, and praying there's enough dots to complete a signal trace.

Besides I need a 'support' break after the last 2 encounters with *luke 'engineers', their email staff and their distributors,
on two separate SIMPLE issues regarding their meters

Here is an example from the SDS1000X/X+ latest FW update. This is from the history & update instructions file located inside the RAR:


Update instructions
- Very important! You must perform the update twice in order to update the oscilloscope from 1.1.1.2.6 (or lower) to 1.1.1.2.13R3 (or higher).The first time will update from 1.1.1.2.6 to 1.1.1.2.13R3, while the second time will update from 1.1.1.2.13R3 to 1.1.1.2.13R3.
 
- Very important! Because 1.1.1.2.15 optimizes self- calibration for the each channel, the oscilloscope will need to perform a self-calibration once if the machine is updated from 1.1.1.2.13R5 (or lower) to 1.1.1.2.15 (or higher)

I'm the 'that guy' who was having the problem,

and would like to thank Siglent America and crew, and the local dealer stepping in, for sorting the issue out asap  :-+ :-+

The communication was as good as it gets, and a few days later was emailed an attachment with the 'missing' .CFG file (not included in the latest firmware update package applied weeks ago) with clear instructions and illustration in a PDF file of how to apply it.  :clap:

The DSO is now up to scratch, and doing the 4 channel dedicated controls plus independent trigger business I need it for  (and glad again I didn't get the Rigol equivalent)   ;D


If Siglent have learned something from this, and blow some days backtracking and sorting through ALL their support pages to verify the download packages offered to customers are complete, and make sense to the average layman/woman/lay-tech,

the only fallout I can envisage from this grand, unpaid, labor of love effort is:

1. Less or no more unnecessary support problems, or time wasted for EVERYONE

2. More confidence in buying Siglent

3. More Siglent orders and test gear SOLD

4. Combination of the above

5. Did I miss anything?   :-//

What advantage does LXI give you over VXI-11?

I haven't used any of the LAN based communications options with test instrumentation.  Both protocols seem to offer SCPI / IEEE 488.2 support.  LXI appears targeted more toward very large systems, such as automating production processes.
Title: Re: Siglent Technical Support join in EEVblog
Post by: Siglent America on June 01, 2017, 01:17:56 pm
The Siglent SDS2000X oscilloscopes are VXI-11 compliant but technically not LXI compliant.

If you want to program a SDS2000X oscilloscope using remote control over LAN you will need to use the NI-Visa layer and I would certainly want to have a copy of the Programming Guide handy. There are some example programs in the guide.

Please contact us at info@siglent.com if you have any questions.

So the difference is ease of use, essentially?

Installing the bloated NI Visa software and getting it working is something that isn't a lot of fun.  If LXI let's you avoid that then I can see the advantage.

With LXI you can open a TCP/IP socket (telnet) and start sending commands. With VXI you'll need the bloated VISA to do the translation from VXI to text commands. LXI is way easier to incorporate in your own programs than VXI.

Hi, first time post on the EEVBlog forum.

I discovered a bug on the SDS1202X-E when using cursors in combination with a 10X probe. I don’t know if it has been reported before. Reading through 27 pages of posts is a bit too much.

Using a 10x probe and having correctly set the probe adjustment under the channel/probe menu doing a measurement with the Y-cursor gives a wrong readout. It divides by 10 one time too much. The same measurement done with the measurement button, and then for example ‘maximum’, ‘amplitude’ or ‘peak-to-peak’ gives the correct readout, properly corrected for the 10x probe. See attached picture for the bug.

Software Version: 5.1.3.8
FPGA version: 2017-03-21
Hardware Version: 00-01
Product Type: SDS1202X-E
Serial No:
Scope ID:

I discovered another bug, which I will post soon. It requires a bit more writing and images.

It is a great scope otherwise!

This is a description of the other bug which I found. It is about X-cursor readouts in the FFT spectrum, in combination with the zoom feature. On the attached two pictures the bug is clearly visible.

In the first picture (E3) you see a minimal zoom, and the ?X readout is 20.26 kHz, which compares fine with the 12.2 Hz/div for the FFT spectrum. In the second picture (E6) you can see that when using the zoom feature (zooming out) the same cursors give a ?X readout of 50.54 kHz, which cannot be right watching the 12.2 Hz/div of the FFT spectrum.

Hope this can be fixed in the next firmware version.

VXI is fine for me.  I use PyVISA (https://pyvisa.readthedocs.io/en/stable/) and PyVISA-py (https://github.com/pyvisa/pyvisa-py) for this.  Works like a charm with the Siglent SDG2042X.  A couple lines of Python code and you're off and running.  Not as nice as LXI, but usable.

Yes, nctnico is correct about this.

Other Siglent instruments will have the open sockets - the SSA3000X spectrum analyzers do now -  but the SDS2000X scopes will not.
FWIW, the majority of customers we work with are okay with the Visa layer but we do understand that it is a large program and can slow things down some.

Just a short addition: Needing to install NI VISA makes it harder to distribute software to customers especially for small companies who can't spend a lot of time on support. Communicating with equipment over RS232 or LXI allows a piece of software to be installed as a single executable without needing third party libraries and reduces the number of ways an installation can be messed up, reduces OS dependancy and in general reduces the number of failure points. From a programmers perspective NI VISA may look easier but from a support perspective it is not especially if the customer doesn't have IT staff on-site.

I'd like to encourage you to continue to expand support for LXI.

It's not just a matter of slowing things down.  It's a matter of being able to easily integrate with modern tools such as scipy.

It is certainly a factor which impacts my purchasing decisions.

Yes, NI Visa is a PITA to install and get working.  Then it seems to be choosy about whether it will keep working...  LXI is obviously a cleaner solution.

Once you bite that bullet, though, does LXI deliver anything significant that is missing from the VXI-11 / NI Visa route?  I noticed that there are some additional functions supported in later implementations of LXI such as the timing synchronisation -- that particular function could free up triggering between instruments, I guess?  (Dependent upon what you're doing, obviously.  I am thinking of aligning manually captured data here, rather than triggering at a set time.)

I am only familiar with the old serial and GPIB instrument control implementations, so the VXI / LXI (and there is PXI, and other stuff) options are new to me.  Is there a good guide that you know of?

Hi boggis the cat.

Personally (and from my experience here and prior test equipment companies), installing and using NI Visa on our test equipment has always been straight forward and starts up the first time with no problems. Of course, I can't speak for everyone but that has been my (our) experience.

I found a couple of NI Visa guides you might check out:

I want to report a possible bug on the SDS1202X-E oscilloscope. Serial decoding doesn't appear to work correctly for History waveforms.  More specifically, if I capture a number of CAN waveforms, the CAN decode display will read the value of the last waveform, not the selected waveform.

Hi,

I found yet another bug on the SDS1202X-E.

1. Feed a sine wave into channel B, Vmin = 600mV, Vmax = 27V
2. Press Auto Setup
3. Turn the vertical adjustment knob twice to the right, so the scale is at 1 Volt per division (note that the purple zero indicator is below the bottom of the wave)
4. And now, turn the vertical position up. Now it is perfectly possible to move the zero indicator to far above bottom of the wave! This is clearly a bug.

Note that if the vertical scale is changed to 2 Volts per division instead of 1 Volt per division, the vertical adjustment works as expected.

Also note that a sine wave on channel A, Vmin = 800mV, Vmax = 10.2V does not show this bug.

Also note that after step 2 on each subsequent turn of the vertical scale knob Vmin gets another value.

After having delved deeper into the last mentioned bug on the SDS1202X-E I have narrowed down the cause of the bug.

Taking a signal with a DC component and using DC coupling on the probe, and switching to different vertical scales the bottom of the wave seems to have rather arbitrary values.

Note: I have done self calibration twice on this scope.

With AC coupling on the probe I have not yet found these issues.
It happens on both channels, so it is not an issue of channel 2 only

Am I overseeing something? I am not an experienced oscilloscope user, but this behaviour of the scope baffles me.

Not really.
There is a bug with measurements as you have identified and it is being addressed at the factory.

Measurements are predominantly made from display information so to not have all the waveform on the display will result in corrupted values returned. There is a tradeoff between amplitude and frequency measurement accuracy depending on how you use the scope.  Same for most DSO's.

This thread investigates some of what you see:

Most instruments will detect out-of-range signal conditions and not display erroneous calculated results.  Is there a reason for not taking this approach?

Regarding the Siglent SDS1202X-E:

I noticed the following bug/inconvenience: in the trigger settings, type 'Slope' the time setting for the "Limit Range <=" is not preserved on shutdown and powering up of the scope. As far as I have noticed thus far, all settings are preserved, although I am not sure of this of course. It would be nice if this would be so.

But: the SDS1202X-E is an awesome scope!

The best approach is to save setups, then load them before starting work.  Unless you have an excellent memory there are bound to be things set differently than you recall, so starting from a 'clean slate' with a known state is the safest approach.

If you're doing any critical amplitude measurements, allow for a warm up time then run the self cal routines.  They take less than five minutes, and can improve the accuracy a great deal.

boggis, there's alternatives to saving setups with the X-E.
The factory Default setup can be now user defined to current settings or returned to factory as you wish.

Post by: boggis the cat on June 04, 2017, 03:49:39 am
Yes, I am aware of that.  It makes more sense to me to save setups for particular usage, but if you always want to start with particular settings it is useful to be able to modify the 'default' setup.

This instrument does seem fairly well thought out in this area.

It would be useful to have more control over the display of measurements (particularly the text size being quite small); and it seems dubious to present known-bad measurements, due to out of range issues -- I can't think of a reason to do this.  If anything, it would be sensible to go the other way and use the frequency counter to warn users of potential aliasing issues with timebase and signal frequency mismatches.

I haven't had much time fiddling with this as yet, though, and hadn't come across most of the bugs reported so far.

Here I captured both channels at 2 ms/div, 7 Mpts, and zoomed in. At zoom of 500 ns/div the zoom window goes blank. It is fine at longer or shorter zoom settings, only blank at this one, and only in the first and last 25% of the capture.

It is true that I had one example on Ch1 and one example on Ch2 but I don't understand how that matters. When the cursors are in track mode, the deltaX calculation (and also the frequency or 1/deltaX) is wrong, regardless of which channel is selected.  Look at the screen copy showing Track Mode (...E31.png). The cursors are set to almost 5 divisions apart at 100ns/div and so the deltaX should be a little less than 500 ns. Instead, it shows 9.360 ms, which would be correct if the cursors were almost 5 divisions apart on the main timebase view of 2 ms/div. I showed the manual mode cursor screen shot just to show the approximately correct value of 468 ns.  Does that make sense?  Thanks.

Behaviour is linked to the trigger channel.  If you change the trigger channel to 2 then the bug appears on the channel 2 trace, and channel 1 looks correct.

Hi boggis, isn't that "bug" called "triggering"?  :-//

You are looking at noise, and asking the scope to trigger at a positive edge of a certain level. So the scope will always show you traces which have a positive edge (and hence a little peak) at the position of the trigger time point. That's what is supposed to happen. Or did I misunderstand your description of the issue?

Or did I misunderstand your description of the issue?
If this is the case, then I don't understand why simply 'waking up' the trigger fixes the issue.

This produces a discrepancy (small, but it is there) depending upon whether you have gone into the [Trigger Setup] menu or not.  Note that you don't have to actually change the trigger.

Edit:

Or breaks the correct behaviour, I suppose.  My thinking is that the noise shouldn't produce a slope like that shown up-thread.

This is the same signal in 'Dot' mode (shorter time base, at 2 ns/div):
(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=321771;image)

Then after selecting the [Trigger Setup] then [Type Edge] (but not adjusting it):
(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=321773;image)

Channel 1 or Channel 2 selected as trigger source:
(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=321775;image)

(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=321777;image)

So your explanation would be correct (maybe) if simply going into the trigger [Type] settings didn't cause the behaviour to suddenly change.  You can't get it to switch back, except through reloading the Default setup.

It just seems odd.  Does it not realise that there is no viable trigger until you enter the [Type] menu?  ???

Edit 2:

You can mess about with the false triggering, too.

Level at zero:
(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=321779;image)

Level at 200 uV:

This is the signal:

With 16X average on all the random noise would average to 0, except at the positive trigger position. Similar with the CH1 kink in Reply#711

On his STOPping of an averaging waveform Reply#709 (https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/msg1225790/#msg1225790) the CML+ does something awkwardly similar on LongMem, in fact it doesn't stop on the last showning waveform it goes and gets another - while STOPped! which is not the one you wanted. Described here (https://www.eevblog.com/forum/testgear/siglent-cml-firmware/msg1110885/#msg1110885).

Reply#703 (https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/msg1225480/#msg1225480) describes an X TB expansion not being part of the waveform, the CML+ can do that as well! either in Delay/Zoom TB mode or just an expansion of a STOPped waveform. It appears to be something to do with the X trigger position being well away from the center X position.

Just not to be left out it can also do the moving 0V marker when there's a lot of the waveform off the screen/out of range, Reply#693. (https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/msg1223792/#msg1223792). That might be normal (whatever that is) for such large overloads, 27Vpp on the 1V/Div. range. Probe and scope on X10 might help.

If this is the case, then I don't understand why simply 'waking up' the trigger fixes the issue.

This produces a discrepancy (small, but it is there) depending upon whether you have gone into the [Trigger Setup] menu or not.  Note that you don't have to actually change the trigger.

Edit:

Or breaks the correct behaviour, I suppose.  My thinking is that the noise shouldn't produce a slope like that shown up-thread.

In my view, the "bump" at the trigger position is actually the correct behavior. The triggering selects traces which have that bump, from the random input signal. Note that the trigger indicator in the upper left always shows "trigg'd" when the bump is visible-

When you enter trigger setup menu, something seems to change. The scope is no longer triggering; the indicator in the upper left shows "auto". No idea why that is the case, and that might indeed be a bug? Does the scope reset or change some trigger setting as soon as yo uenter the menu?

I would expect it to not trigger consistently when in the noise floor, so it seems that the post-menu activation behaviour is 'correct'.  (Although it is debatable' I guess.)

This 'scope has a 'digital triggering system' (or words to that effect) -- i.e. the triggering is software driven -- so it is down to how it interprets the data stream as it processes it.

That is my assumption.  The [Default] operation is not setting the trigger behaviour correctly, then when you open that menu it refreshes the trigger immediately and clears the problem.

So, if this is a bug, the work around is to open that menu, or otherwise 'activate' that code.

Once it is in that post-menu behaviour you can't get the initial behaviour back, so it seems that this is the true intended 'default' behaviour for the trigger.

I don't think boggis's Probable bug spike in Reply#709 (https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/msg1225790/#msg1225790) is a bug. With 16X average on all the random noise would average to 0, except at the positive trigger position. Similar with the CH1 kink in Reply#711
If this were the explanation, I don't see why just opening the trigger menu would make the trace change.

I agree there seems to be something odd going on, but I don't think 400uV of noise at 30MHz would be the best place to test it, much of that noise will be from the scope itself and would vary a bit depending on its settings, and even depending on what's on the LCD.

Your Another trigger bug Reply#715 also looks odd, turning peak detect mode on should show at least some of the very narrow transitions. With such a low frequency, slow timebase speed, and large memory are you sure it's not sticking in the pre- and post- trigger data gathering times.

We are not on the same page here. The scope should trigger "consistently" whenever the signal crosses the trigger threshold, going positive.

If you look at where the 0V trigger threshold is shown on the screen, and where the signal is, there seems to be a small negative offset on the signal. Hence, the trigger will "pick out" slightly higher, positive-going peaks on the signal. And the scope will consistently show these peaks at the horizontal trigger position.

Do you know if they are fixing the issue in which serial decoding isn't done for history frames other than the last?
AFAIK none of Siglent DSO's do this yet. I tried some time back with 1kX and 2kX of which the UI is very similar.

I'll ask if there are plans to implement it.

This seems to be what is happening, initially.  If you look at the 'dot' display screen-grabs, there is an obvious rectangle where negative signal is absent, to the right of the triggering point.

However, as soon as the trigger is refreshed, this behaviour changes.  Then it maintains this behaviour until you perform a reset (using the [Default] button, with factory settings in my case).

Hence, the trigger will "pick out" slightly higher, positive-going peaks on the signal. And the scope will consistently show these peaks at the horizontal trigger position.
But this isn't consistent.  As soon as the Trigger [Type] menu is opened (you needn't actually alter the setting, just open that menu) it changes behaviour, and maintains the new behaviour from then on.

The new behaviour is as I'd expect, where it doesn't trigger because there is nothing to trigger on.  (I haven't seen the initial behaviour in any 'scope before.  It is quite a common part of calibration practice to have a ground setting when testing the vertical gain accuracy, and generally with the averaging function set.  That is why the 'spike' got my attention -- it isn't normal to see that, and it certainly isn't normal for it to then vanish because the instrument changes it's mind...)

So either this is a 'feature' that disappears as soon as you go near the triggering, or it's a bug.  I think it's a bug.

(Not a major bug in itself -- but what does it point to in terms of how the 'scope is being initially set up?  I suspect there are errors in that process, leading to this initial behaviour.)

"The new behaviour is as I'd expect, where it doesn't trigger because there is nothing to trigger on."

How can you say there's nothing to trigger on when we can see the nearly 1 division high sine waves are still there, as in Replies #711 and #714. If you've carefully set the trigger level to get a view of the noise, you shouldn't loose that ability for no apparent reason.

I agree with ebastler that being able to trigger on the noise is the normal behavior, we've been doing it for years! after all, how do you know if it is random noise or a small signal, until you trigger on it.

Normal trigger is usually better than Auto trigger, although it's also a pain to use when the amplitudes are very low.

Quite unlikely random wild guess:
When opening the trig menu it checks it's on the 500uV range, realises an amplitude of 0.8 Div. is likely to be just noise, so doesn't bother triggering on anything less than 1 Div high.

Someone else with a SDS1202X-E ?  should try to reproduce it.

Hi,

I think I have found another small bug in the SDS1202X-E software. It is about using a tracking cursor on FFT in split screen mode:

1. Open up FFT in exclusive screen mode
2. create a cursor on the MATH channel
3. set the cursor mode to TRACK
4. on the MATH channel, set the display mode to ‘Split Screen’

Now you will see that the cursor on the FFT is still visible, but in the wrong window. It is visible in the signal trace in the top window, not in the FFT window on the bottom. See the attached picture.

Note that this only happens on a tracking cursor. On a manual (either X or Y) it works fine.

Ignore the examples with sine interpolation set on, and look at the samples using 'dot' traces.  That is the actual data that the 'scope is working with.

The initial data is very odd, and obviously non-uniform in sampling.  The post-'trigger [Type] menu open' operation yields a quite different looking display.  This is what I would expect to see.

I think that the behaviour must be due to the way triggering is being implemented in software.  The initial behaviour is due to the setup process (from [Default]) being broken, then the correct routine gets run as soon as you open the [Type] menu, fixing the odd behaviour.

It's a bug, and points to other possible subtle issues.

Thanks for posting that.  Note that the video seems to show a consistent behaviour, with no change occurring.  Whatever algorithm is being run to calculate the trigger point stays the same.  This didn't appear to be the case with the Siglent -- but maybe it is just being modified in some way.

After more fiddling, it appears that you can (with patience) get back to the first type of behaviour.  Sometimes.  Unless I was hallucinating, because now I can't get it to do that again.  :-//

This initial result (Auto trigger mode, but that doesn't matter)...
(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=321771;image)

...is not the same as this second result (obtained by simply opening the trigger [Type] menu -- not changing it):
(https://www.eevblog.com/forum/testgear/siglent-technical-support-join-in-eevblog/?action=dlattach;attach=321773;image)

No change to any settings was made, but the 'scope seems to re-evaluate the calculation -- either the algorithm gets re-started or some other process is involved.

Secondary point, not related to this bug (which is more of a weird aberration, as you can get back to that first behaviour with some effort) -- I consider the second screen-grab above, to be 'correct'.  The only way it could find a genuine trigger point would be if the algorithm found something that looked like a trigger.  If you look at the first screen-grab you can see that rectangle where no data points are present to the right of the central graticule (the trigger point).  That is an artefact of some kind.  It is persistent, and anomalous.

You should set the dot mode of your Rigol and see if you get the same artefact -- that rectangle of exclusion.  If so, the same algorithm must be in play.

Why the action of opening the trigger [Type] menu might restart the algorithm is explicable by the code restarting (interpreting it as 'restart the calculation with this trigger type') -- but the result changes, so some recalculation must be occurring.

Whether this has any practical effect when triggering on real signals, I don't know.  My second possible bug issue (with the pulse with an embedded 'glitch') seems to be a triggering issue, and has a similar 'solve by doing nothing (except opening the menu)' solution or work-around.

Consistent, predictable, behaviour?  Too boring, I guess.  (I bet the code running on this 'scope looks... interesting...   ;D)

Well:  :horse:

If I have nothing better to do sometime I may try to figure out what is going on here, but for now the underlying logic (?) eludes me.  I'm still calling this a bug.   :-BROKE

I'll try one last time; but I think I might just not be able to get my point across to you. (Or I continuously miss your point...)

If you have one sample below the trigger threshold, and the subsequent sample above the trigger threshold, that constitutes "a genuine trigger point". Because you have set the trigger condition to "positive edge", right?!

So, your scope is sitting and waiting, looking at a random sequence of samples which are above, above, below, below, above, below... the trigger threshold. The scope sits and waits until it sees a sequence of "one sample below, followed by one sample above the trigger threshold". Then it triggers. And it displays the sample sequence, centered at the trigger time point.

And guess what: The sample to the right of the trigger time point is always above the trigger threshold!!  Which is what your display shows, and what you describe as "that rectangle where no data points are present to the right of the central graticule (the trigger point)." And which is what you explicitly asked the scope to look for and trigger on.

So?!  :-//

Goes something like: Auto, 200mV, 2V, 20V, 200V.
They are essentially sensitivity settings. eg. with open inputs at highest sensitivity you'll probably get ~2x mains frequency. Select a higher setting where the surrounding EMI/RFI does not meet thresholds and the display should show 0.000000 pHz.

I guess most users will just let the Auto setting sort it out.

Do you think it likely that an entire block of sample points would happen to cluster in the manner that you see in the first screen-grab?  Statistically highly unlikely, for a single event.  For repeatable events -- can't happen.

No, because the data to the immediate right of the trigger point should be as random as any other data on-screen.  (This isn't with averaging mode set, in case that is what you're thinking.)  In other words, you shouldn't be able to discern a difference in the displayed signal in noise (or some other type of random signal source), even if you can get repeated triggering -- by setting the trigger threshold down in the noise.  The second screen-grab is closer to the 'ideal' correct display.

First -- did you notice there are two behaviours shown?  There was no change to triggering involved.  So that seems to be some form of bug.

The second point concerning triggering behaviour on noise I covered above.  That is a more 'general' issue as it seems that at least some other 'scopes exhibit the same artefact.

What is seriously missing:
No fine time base adjustment, at least what I could found.

What is driving me nuts:
Automatic roll mode for long timebase. If I want roll mode, I will turn it on myself, thank you.

What I would appreciate:
Better UI for FFT. I'd really like to set start, stop. Or use left half of screen, if I'm in a low frequency region.


What keysight X1000 can do - and siglent could probably too if wanted.
Trigger on channel that is not enabled. So you could use all of the memory for the one channel you are using.
Use trigger input as a digital channel.

Otherwise quite nice small scope, there are some features which I really like. I have it side by side witch X1000 - I'll share with my experience when I have more "wheel time"

EDIT:
Full-screen mode would by really nice. A way how to hide all of the menu, and expand trace to full screen. Cursors/measurements transparent in corner.

Huh?! The display shows the overlay of many scans. You specifically set up the scope to trigger on a particular pattern (positive edge), and it is showing you events which exhibit this pattern.

I never disputed that the change of behavior upon opening the trigger menu is an issue. I just tried to explain to you that the first behavior (where the scope is triggering on positive edges in the noise signal) is the correct one.

The SDG2000X uses the term "TrigLvl" for this, which seems like a better name than "Range".  "Range" in a frequency measurement mode implies a frequency range to me.  Maybe "TrigRng" would be a more clear label here?

All that i can suggest is this:

In your spectrum analyzer range dont offer options, include everything and offer a best  price that puts the competition to shame.

I can understand from a profit point of view why options make good sense, but from a practical end user point of view having every available option  makes a lot of sense.

A good example is the EMC and  Advanced Measurements options, I dont really see why these should be options on a Spectrum analyzer. I never feel loyalty to a manufacturer when I feel like I am getting milked.

The other point is that we have to pay sales tax on many options its far better to pay the tax on one price that includes options rather than multiple  charges as you option up the instrument. I would think it also reduces distribution and handling costs as well.

I agree that any behaviour like this should be selectable.  Some people seem to prefer the automatic switching to roll mode, so it would be smart to put this in an options menu.

There is a potential issue with customer support when you have a lot of configurability, but this can be easily dealt with by the restore to presets option.  Items such as digital cameras can have hundreds of options, and it is assumed that the user will know what they're doing.

Hey, guys, I sort of have an issue with triggering that worries me. Basically, my sds1202x-e does not reliably trigger when I put triggering level close to the bottom of waveform. It also looses triggering when I change vertical scale. Please see this on the video:  https://goo.gl/photos/AC14aGX4sPcB3E599 (the signal source is sdg2042x with latest firmware).

How I noticed this: there were some periodic glitches on the screen for 5+MHz sine signal (like, every 3-5 seconds it lost triggering for a moment, no problems on low frequencies). I started to play with the parameters and found that trigger sometimes does not work the way I expect and the way I saw it working on other scopes.

Guys, please advice. Is me doing something wrong, is it a faulty hardware or a software bug? If it's a hardware I would like to send my unit back to the seller till it's possible...

PS Sorry, tautech, for reposting, but my 14 days return period is expiring soon, I need to make a decision. I'm a bit nervous :(

I picked up an SDS2204X with MSO option from Saelig a couple weeks ago and had the first opportunity to use it in anger this weekend.

The digital interface worked great.  The screen is so much nicer than the old Rigol I had been using.

One thing that's taking some getting used to is switching from the "filter" feature on the Rigol to "Eres" on the Siglent.  I live close to the loop in Chicago where all the radio and TV transmitters are located.  I can clearly make out every radio station in Chicago on my FFT.  So filtering the signal is a must.  Otherwise there is 50mV of noise centered at 98MHz.  (If you have suggestions for minimizing this problem, I'm open to listeneing.)

One issue I had on the analog side (when using only analog input) was that the trigger indicator would go missing and I could not bring it up on the screen.  It would tell me what the trigger level was, and I could see the effect of changing it on the trace, but the dotted bar would not show up.  Is this a known issue?  I wish I knew how to reproduce it but it "just happened" a couple times. Turning off the scope would make it work again.  Is this a known issue?

Adding additional external attenuation at the inputs is all I can suggest.
I had a look at this issue using a 2" coax loop, FFT centered on 100 MHz and I too can clearly see our FM band from transmitters some 10 to 20 miles away. Screenshot attached.

It might just be user error. If the trigger level is set to ~ 50% of a waveform and the sensitivity increased the trigger will travel upwards and sometimes off the display. In these cases the trigger level indicator will be at the top right of the display and pointing upwards not outwards into the display area.

When you've lost the trigger.......and you have Auto triggering set, press the trigger level control to automatically set the trigger to 50% of the waveform amplitude.

I could see the voltage level of CH1 and the trigger voltage level in the little info boxes on the right hand side of the screen, so I knew what the trigger level was set to.  And I could see the effect of changing the trigger level of the signal.  The full waveform of the signal was visible on the screen.  I just could not see the trigger level indicator.

Sounds like no one else has seen this issue.  I'll have to grab a screenshot if it occurs again.

If remember correctly, trigger cursor disappears when AC-coupled. This was quite annoying. It still indicates on the screen current trigger voltage. Can't check on my unit as I packed it to ship back  >:D

Hello.
I recently purchased model SDS 1202X-E. Very fast and functional. But very uncomfortable interface. Showing only 4 measurements, and very small font size. Before that, I used the oscilloscope Hantek DSO 5102B in my work, and there was a very convenient display of all measurements, 8 of them at once - and all in large font. I propose to make the font of the numbers more 2 times, and the name of the parameter itself - to leave small. So it will be much clearer to read and it is more convenient to work with the device.

For comparison: (Hantek 5102B and Siglent 1202X-E):

(http://savepic.net/9474471m.jpg) (http://savepic.net/9474471.htm)

And one more drawback - if there is no measurement of some parameter, then do not show three stars ("***"), but just leave an empty space. So there will be less unnecessary meltesheniya on the screen, which without it is well loaded with information.

A big request in future firmware is to fix this small - but very unpleasant lack of such an excellent device.

On my SDS1202X scope i got offset jumps when switching between different voltage ranges and time bases.
For example on channel 1 using 200 mV/div, when crossing the timebase boarder from 5us->2us using a single channel and from 2us->1us using both channels.
I did the self calibration several times without any change.

Here are some examples of my offset values:
(In every vertical scale i stepped through all time-bases and took the worse looking one)
----------------------
-9 mV @ 5 mV/div
-10 mV @ 10 mV/div
-7 mV @ 20 mV/div
-8 mV @ 50 mV/div
-8 mV @ 100 mV/div
+40 mV @ 200 mV/div
+40 mV @ 500 mV/div
-120 mV @ 1 V/div
-320 mV @ 2 V/div
+400 mV @ 5 V/div
-800 mV @ 10 V/div
-4000 mV @ 20V/div
+4000 mV @ 50V/div
-8000 mV @ 100V/div

Are these offsets normal?
In the datasheet on page 6 they state:

Quote
Offset Accuracy:
    ±(1%* Offset+1.5%*8*div+2 mV): ?2 mV/div
    ±(1%* Offset+1.5%*8*div+500 uV): ?1 mv/div

Can anybody give me an example how to calculate the maximum offset error for e.g. 200 mV/div?
Many thanks!

rfspezi, I think I had a similar problem with mine.  It went away after I did a self cal after letting it warm up for over 30 minutes.  Previously I had done a self cal after only letting it warm up for a few minutes.
There seems to be something odd going on during the warmup.  If I crank the gain up at startup, I'm seeing the traces jump about 1/3rd a division in distinct steps every 10 or 20 seconds, starting around div and a half out.  After about 30 minutes they settle down to bang on 0v.  This isn't an analog drift but a very distinct jump to a very precise position.  Sometimes closer to zero but sometimes away, but always eventually ending up at 0.  I've tried it with terminators and it does the same thing.   I suspect it is some sort of warmup compensation routine that actually doesn't do any good.

I made 2 reviews about the SHS-1062 number 1 https://youtu.be/R5lTLuclk1M
While doing that I found a bug. In scope mode when I use the run/stop the trace disapears after a short while (I noticed that a few days after the review while using it)

Yesterday I powered it up while it was in in log mode. I pressed on scope and the 2 modes "merged"  I had to repower it to go away.

The accuracy is not bad but the RMS value in scope mode is a bit off, but only at lower voltages

Continuity sucks but that is not a bug. The DMM IC is made to use a LCD display and I think they use the rs232 to talk to the rest of the scope. Maybe that is to slow. It takes several seconds to beeb

The menu structure can use a big update. Sometimes you need the menu button to select, sometimes the "right arrow" etc

The inverse color can use better combinations to make it better readable (more contrast instead lightgreen, yellow)

But beside this faults I really like this scope, a pity it has to go back to the dealer next week.

I know Siglent see all that's in this thread and more that I and others point them to.
TBH I think the SHS FW needs some freshening up as HH's are gaining in popularity, not only for portability but isolation from mains ground. The FW we know today is much the same as when I first sold Siglent and needs smartening up some to be competitive.
What they will do I have no idea but they have in the past reworked FW like in the SDS2000 to end up with a better  GUI.
By all means put some suggestions forward.

I own a growing collection of Siglent test equipment.  Two of the items that I have are the SDM3065X and the SDG2042X.  They appear to use the same (or very similar) rubber bumpers on the front and back.  These bumpers have a bump on one side (top or bottom) and an indent on the opposite side into which the bump will fit.  This allows gear to be securely stacked on top of one another.  Or, rather, it would if Siglent bothered to always install the bumpers so that the bumps (feet) were down and the indents were up.  However, on the two items mentioned, they are opposite one another.

Siglent, please standardize the installation of the bumpers, preferrably with the bumps facing down on all of your equipment.

Also, please consider securing the nuts on the inside of the case.  I swapped a pair of bumpers on the SDG so the two would fit as described and had a hard time getting a couple of the nuts to stay put while I put it back together, and almost lost one inside the gap between the case and faceplate.

One other item: consider adding graphing options to the frequency counter on the SDG2000X series.

They have and I knew this too.  :palm:

From factory tech support: (abbreviated)
In the last year or so the bumpers have been standardized but you have got models from pre and post standardization.

IIRC a later model I looked at did have captured nuts so to overcome the problem you describe.

Probable bug

Setup to recreate:
  • No signal applied
  • [Default]
  • Ch 1 [V/div] to 500 uV/div (must choose a low setting, as hard to notice at 2 mV/div and greater)
  • [Acquire] > Average 16
  • [Measure] > Clear, then add Type > Mean
  • [Menu On/Off]
  • [Clear Sweeps]

Question about this behaviour

After pressing [Run/Stop] to halt acquisition, the display seems to change to the last waveform, rather than maintain the averaged waveform.

There is a change in behaviour.  The 'new' behaviour then sticks, and is what I consider correct.

So no, it isn't "normal".  Either the initial behaviour or the subsequent (different) behaviour may be normal, but they can't both be.


Edit:

Retesting this seems to indicate that it is only real noise sources (e.g. shorted or open terminals) that produce the aberrant triggering.  It is also progressively less pronounced as you move to longer timebases.

Using a pseudo-noise source (multiple modulated sine waves, from a Feeltech Arb device) or a repetitive signal yields the expected triggering behaviour, after "Default" settings.  No fiddling with the trigger menus is necessary.

In practical terms, this isn't likely to be particularly significant.


I did also try to reproduce the other triggering issues reported, and could not get the issues described -- although the triggering behaviour does seem a bit marginal in some cases.  There is a significant 'dead band' of around half a division where edge triggering doesn't seem to work (checked using sinusoidal and similar repetitive waveforms, exists at the the base of the signal for positive edge and vice versa), and the line indicating the trigger level does indeed vanish under certain circumstances.  So there are some behaviours that are not ideal that could be looked into, as well as the trigger indication bug to be fixed.

I am looking at Siglent's generic Programming Guide For Digital Oscilloscopes Series (http://www.siglentamerica.com/USA_website_2014/Documents/Program_Material/ProgrammingGuide_forSDS.pdf) (warning: PDF link) that is available from the SDS2000X documentation section and from the global documentation area on Siglent America's web site. I do not see any instructions for accessing the AWG functionality.  Nor do I see any commands documented for the logic analyzer portion of the device. Please provide an update for this.

My immediate quest is to get a screen dump over VXI-11/SCPI .  To that end, I am trying to understand the "SCREEN_DUMP" and related "HARDCOPY_SETUP" commands.  But SCDP just seems to hang the VXI-11 session when using PyVISA and PyVISA-py.  Screen capture seems to work for EasyScopeX, so there must be some way to do this.  Based on a network capture, this should work:

Code: (python) [Select]
#!/usr/bin/env python

import visa, sys
from pyvisa.constants import StatusCode

rm = visa.ResourceManager('@py')

# Siglent SDS2204X
scope = rm.open_resource('TCPIP::sds2204x')
sys.stdout.write(scope.query("*IDN-SGLT-PRI?"))
sys.stdout.write(scope.query("*CHS?"))
n, status = scope.write('SCDP')
if status == StatusCode.success:
    print("Success...")
    data = scope.read_raw()
    sys.stdout.write(data)
scope.close()
rm.close()

Unfortunately, it just hangs at "scope.read_raw()".  Running the same code on my Macbook Pro using NI VISA drivers results in this error in the same place:

Code: [Select]
pyvisa.errors.VisaIOError: VI_ERROR_INV_PROT (-1073807239): The protocol specified is invalid.


Siglent,

1. How do I download a screendump image using SCPI from an SDS2204X?  Please docurment the SCDP command adequately.
2. What is the format of WF parameter "DESC"?
3. How do I access the digital channel data via SCPI of this MSO?
4. How do I control the scope's AWG via SCPI?  This is apparently possible since EasyWave can talk to it.
5. How do I read frames from the segmented buffer via SCPI?
6. Shouldn't the "MSIZ?" query return "MSIZ 140M" on the SDS2204X?  It returns "MSIZ 14M".
7. You'll notice that I am using two undocumented SCPI commands in my code.  How about documenting these for those of us playing along at home?

The SCPI command interface for this scope is woefully inadequate.  Look at Rigol's SCPI documentation for comparable scopes: a well thought-out command structure, and detailed documentation.  Siglent's SCPI support and documentation seem rather amateurish in comparison.  Please provide SCPI controls for the AWG and digital inputs.  And please update the documentation.

I'll have to read through this.  At first glance, it doesn't appear that any of my issues have been addressed.  The SCDP command is still completely undocumented.  I see nothing for the AWG or digital channels.

That said, I have SCDP working with PyVISA-py now.  It still fails with the NI-VISA drivers on OSX.

https://gist.github.com/mobilinkd/8a07cc124946c87715c6a1458118411e

This will do a screendump over the network from a Siglent DSO.  It should be easily adapted to use USB.  I would like to get this to the point that it automatically transcodes the image to a reasonable format like PNG.

I am trying to measure two audio waveforms on CH1 and CH2 on my SDS2204X.  CH1 is a filtered and amplified version of CH2.  I have the scaling of the two channels adjusted so that the waveforms are superimposed on one another.  I have the trigger mode set to Auto.  Acquisition mode is Eres @ 1.5 bits.  When the scope is in Run mode, the two waveforms are closely correlated as expected.  When I press Stop, the waveforms are uncorrelated.  The two channels do not appear to be stopping at the same time.

If I put the trigger mode to Normal and put the trigger level near the limits of the signal so that it is not triggering frequently, the waveform is always correlated when triggered, but I can still get an uncorrelated waveform by pressing Stop if more than one trigger event occurs in rapid succession.

This is driving me nuts. This seems like a bug to me.  Am I doing something wrong?  Have I missed some subtle detail in the User Guide?  Or do I have no right to expect that Stop will stop both channels at the same time?

* Addendum: this only seems to happen in Eres mode.

There is a significant 'dead band' of around half a division where edge triggering doesn't seem to work (checked using sinusoidal and similar repetitive waveforms, exists at the the base of the signal for positive edge and vice versa),

Please can you define it more accurate. Do you have any  documented and trusted data for this?

Do you perhaps mean that trigger hysteresis is bad thing? There is trigger level hysteresis - and there need be.  I believe that mostly peoples in most situations do not want zero hysteresis for edge trigger.



This oscilloscope do not have freely adjustable trigger hysteresis setting(1) as example in some Rohde&Schwarz models. Siglent have selected some average good compromise for this.

Normally there is around <0.3 vertical div hysteresis  "window". When trigger is DC coupled, as usually is, and if edge trigger is rising edge, hysteresis treshold is below triger setting level and "trig" treshold is at trigger level. If falling edge is selected trigger hysteresis treshold is overside trig level setting and final "trig" treshold is trigger level. For trigged acquisition signal need cross both these treshold. After then waveform position is fine adjusted to trig time position. Fine positioning have  much more resolution than sampling interval due to "oversampling" - fine interpolation.

(1)There is one selection what change trigger hysteresis. In trigger set menu there is  "Noise reject" on/off. Normally (default) it is off. If user turn this on, trigger hysteresis is more wide. Around nearly 0.8 div. (upper or lower side of trigger level set, depending if rising or falling edge is selected.)

Benefits of R&S RTO digital trigger system (pdf) (https://cdn.rohde-schwarz.com/pws/dl_downloads/dl_application/00aps_undefined/Benefits_of_RTO_digital_trigger_system_2.pdf)
Page 10 about trigger hysteresis. Also whope paper is good to read for better understanding digital trigger system. Albeit this Siglent model is lot of more simple machine but still it follow these basic principles.

Knowing how equipment really works is very extremely important for avoid misconceptions and false claims.

Previously in this thread was also other total mess where signal was noise and wondering how it show peak in trigger position. Jus due to lack of enough knowledge and experience about how these things work even in basic entry level things.






Then:
Quote
... and the line indicating the trigger level does indeed vanish under certain circumstances.

Can you define it with facts anbd details (data! instead of opinions). And the reasons why it should be different, taking into account all the relevant factors.



Here some simplified case what perhaps make this trigger hysteresis more clear.
Only show Edge and rising. Falling edge trigger: this hyst is also just opposite direction.

Cursors are used here only for show trigger hysteresis treshold levels. (hysteresis window borders)

In first image trigger looks bistable because there narrow hystereis but signal have this sawtooth "noise" and trig conditions are met more than one places.

Second image have wide trigger hysteresis and now signal loogs rock solid on the screen.

Images have adjusted for clarify this thing, not for show "nice looking image". This is also why signal is extremely simply.
For better show more rare trigger position (exist only in first image) there is used 5 second persistence in both images.

There is a significant 'dead band' of around half a division where edge triggering doesn't seem to work (checked using sinusoidal and similar repetitive waveforms, exists at the the base of the signal for positive edge and vice versa),

Please can you define it more accurate. Do you have any  documented and trusted data for this?
No, not using the cheap Feeltech Arb I have at home.  I only checked up to 5 Vpp, too.  The edge trigger drop-out may improve at higher V/div settings.

This is just general observations of behaviour.  Finding the exact points would require better signals, and be a bit pointless as there is no specification.

Quote
Do you perhaps mean that trigger hysteresis is bad thing? There is trigger level hysteresis - and there need be.  I believe that mostly peoples in most situations do not want zero hysteresis for edge trigger.
The algorithm used does have to ensure that a stable edge has been found.  I would think that three data points would be sufficient to establish that, at a minimum.

Without knowing what the 'scope is expected to do it is difficult to differentiate a bug from intentional behaviour.  However, the broader you make that 'dead band', the less useful the triggering is.

Quote
Also whope paper is good to read for better understanding digital trigger system. Albeit this Siglent model is lot of more simple machine but still it follow these basic principles.
It is the specific implementation that is the issue, not the principle.  We don't know much about this.  The specifications are quite sparse.  (This isn't documented in the manner of a high-end Keysight or Tektronix 'scope.)

Referring to a white paper from another manufacturer doesn't tell you anything about Siglent's implementation.

Quote
Knowing how equipment really works is very extremely important for avoid misconceptions and false claims.
You have this backwards.  Testing the equipment yields how it "really works".  If we don't know how it is supposed to work (insufficient documentation), then we cannot tell if it meets its specifications.

Quote
Previously in this thread was also other total mess where signal was noise and wondering how it show peak in trigger position. Jus due to lack of enough knowledge and experience about how these things work even in basic entry level things.
The behaviour I noted isn't correct.  Just because some Rigol 'scopes also behave oddly in a similar manner doesn't make the result correct (and if I recall correctly, Siglent is the older company, so I would guess that the algorithms got 'borrowed' by Rigol) -- you have to consider what the ideal is, and if the result departs from that in a systematic and aberrant way.

I noted that the pseudo-'noise' from the Feeltech Arb I have is triggered on as expected -- all of the sinusoidal-based waveforms are centred as expected, with either rising or falling edge set.  Real noise, such as amplified open input (setting the V/div to small values), produces some odd 'stacking' effects.  In some circumstances, initial results will change by simply opening the trigger menu.

Given that triggering consistently and predictably on noise is not a practical concern (we use 'scopes to inspect signals, where defined trigger points are important), this may not matter for usage.  It may indicate problems or limitations in the algorithms used, however, so noting such behaviour might be of some use to those writing the algorithms.

Quote
Then:
Quote
... and the line indicating the trigger level does indeed vanish under certain circumstances.

Can you define it with facts anbd details (data! instead of opinions). And the reasons why it should be different, taking into account all the relevant factors.
When you adjust the trigger level there is a horizontal line to indicate where that level is, along with the numeric indication.  But that line will disappear under some circumstances.  Also, it seems odd that if you change from DC to AC coupling the trigger level is still settable, but only the numeric indication is present (and persistent, it doesn't snap back to zero).

There are a few odd bugs of this type, and other people have already documented them fairly well here.

ther things just  |O

 :bullshit:

Lets take this case: Missing trigger level indicator when trigger coupling is AC.  |O |O
Also it looks like you do not know how trigger coupling AC works and what it means. Please study first and after then claim bugs.
(it works perfect and also there is NOT level indicator, and there must NOT be)

You can demonstrate this your self how it works and after  you have done your home works come on again and explain what you see and after then please arguments (and please think carefully before show your arguments) for trigger level indicator mark.

I will set this home work example like this: If you do not have equipments for this please take pen and paper and demonstrate this example.
There is 2Vpp example 28MHz sinewave what is riding on very low frequency signal, nearly like drifting dc, say example 0.2Hz 3Vpp sine or example triangle wave (with these settings it is nice to see on display and immedatelly can understand why there is not trigger level pointer or trig line over screen..

Now connect this signal to scope, set 50ns/div and 1V/div and DC coupling. (because in this example case we want also know this level)
Now set Trigger for rising edge and coupling AC and set trig level zero (remember it is now relative level).

What you see on the scope screen. Specially look how is signal relative to trigger position.

Now change trigger coupling for DC and try trig normal and auto.

What you see now.  Again specially look how is signal relative to trigger position. And tell how it trig, is it fun.

After then you are ready, come on and tell how bad it is that trigger vertical level marker disappear when we go to trigger AC coupling.

Think, think again.

But at this tim I feel this is waste of time. Previous message you just deny nearly all and keep tightly your all opinions what are based only to nothing or  based on beliefs. Just as for noise trig and now with trigger hystreresis... perhaps next is just this trigger AC coupling.

Please keep free your opinions but with this level of knowledge do not so much claim bugs in these  things what works perfect and just right. Yes, there is also bugs but they are not at all these things.

Tiny add to previous msg.

There is Dave's old youtube what explain trigger coupling AC/DC because this very basic function confuse some peoples who have equipments but who do not know how to use these and how they work.

There is some flaws or negligence in this video but these are not important in this case and this video is good for explain this function (partially).

<iframe width="640" height="360" src="https://www.youtube.com/embed/y5aAjd9YPok" frameborder="0" allowfullscreen></iframe>

https://www.youtube.com/watch?v=y5aAjd9YPok (https://www.youtube.com/watch?v=y5aAjd9YPok)

In this video he show Rigol and in nearly end also Keysight and then also how Keyshit have  trigger level 50% function and how it works (but Z box do not have).

Siglent have same 50% function as in Keysight (but without this enormous noisy front end).

Also you can see how also Rigol trigger level mark disappear (right,  it need disappear) just as also in Siglent but some peoples think this func is bug because it is in Siglent.  |O

This isn't what I stated.  The level indication (the line) disappears sometimes with DC coupling set.

Other people have noted this issue.

No, you aren't following what I wrote correctly.

"Also, it seems odd that if you change from DC to AC coupling the trigger level is still settable, but only the numeric indication is present (and persistent, it doesn't snap back to zero)."

The numeric indication for trigger level is present, with AC coupling.  There should be neither indication, as you can't meaningfully set a trigger level.

Do you have this model 'scope?  It seems that you don't.  There seem to be some weird interactions with settings and incorrect behaviours.

Boggis, I appreciate that you're trying to find bugs and you probably have found several.

However, in the case of not displaying a line when you go to AC-coupled triggering, I am with rf-loop that this is not a bug - it should show a numeric level but no line on the screen.  Watch Dave's video above which is absolutely on point, particularly after 17:17 if you want to save time.

I'm waiting for the new firmware but meanwhile, I'm using the SDS1202X-E and it is doing just fine; I have yet to experience a bug that's stopped me doing anything I have wanted to so far.

I have one other thought/theory about the phantom blip you see in the center of the screen when nothing is connected to the input; digital cell phones pulse RF energy out (try holding one near your speakers) and, even with nothing connected, even with maybe a scope probe connected where the tip is shorted to the ground croc-clip (which forms a small loop antenna), a real signal pulse is being detected which is causing the triggering. Putting a shorted BNC connector on the input might not even make this go away as the PCB trace inside the scope between the BNC connector and the ADC front end might be enough to pick up a signal.  However, I see this as an exercise in futility if you're looking for bugs with no input connected!  My Agilent and Fluke multimeters show fluctuating voltage readings when I have nothing connected to their probes  :wtf:

Yes I have and not only one and test unit have been just after this model was ready for markets. How you think I can other way publish several tests and result images and define how it works and data and knowledge about it in things what are not told in specs.
Just one example, this. Not possible without scope:

Also I have SDS1000X+ model, SDS2k, Several other brand scopes, including also old boat anchors. Previously lot of more but this kind of retired people do not anymore need so much.

This is just ok how it should  work.

Then

....... (and persistent, it doesn't snap back to zero)."


this is like design compromise. One like red and other like blue...but some like hot chili.   When people push coupling at this point system do not know if he step over AC and to example HF rej. If he wANT hf Rej then it is wise to keep untouched (as DC).
Some users may need often just HF rej and some other just LF rej or AC.  So, compromise is that do not change user defined trigger level. If user want he can just push one button and there it is. It need note  that 0 is not at all mostly optimum for AC coupled trigger level setting.

Use trig coupling DC and look narrow pulses. Example 3V positive peaks and 1kHz but pulse width say example 1us. Press 50% or set 1.5V trig level. Ok nice trig and all ok but reason or other you want trig AC coupling. Nice, it stay trigged. If it change itself to zero then you need adjust it for trig again.

These kind of things need compromises. Allweays some combination  is not so nice. 

I do not want change it. Overall ok compromise. But user need study his tools. Know your equipment helps in many places and. Learning curve is ....  if you want learn instead of ranting what nearly inhibit learning.

More useful is learn how to use it and how it works. Then when meet real error/bug  then need do real documents with all nessessary and enough accurate data so that peoples in factory can repeat it. Findings what nobody can repeat / reconstruct are waste of time.

1. besides pressing Auto can you turn on these values manually?
2. When displaying 2 channels can you get both of their parameters displayed?
3. my friend pushed some buttons while I wasn't watching and got it to display ch2, but then it went back to ch1 and we couldn't figure out what he did to get ch2 back.  how do you select which channel to display?

No, only the menu, the measurement, which occupies a useful part of the screen.
Strange discreteness of automatic measurements of an oscilloscope. 220-224-228V  :o

In one claim to SHS806, I was mistaken, the delay between channels is regulated by it, and it was not set to zero.

There is also a hardware bug at the 800 series.
With DC offset, especially in the 2V/div range, the error of the position of the scan line relative to the marker is large, on all the devices that I saw, it does not fit within 3% tolerance.

Despite all the bugs, the device is very useful for me. It's a pity that Siglent will never fix them.  |O

I do know what's the difference between AC/DC means. And I still prefer trigger level to be displayed at all times (it's like you can measure min/max values of waveform regardless of channel coupling) with coupling indicator on the marker itself. Just because you don't like this approach does not mean people who don't share the same views are idiots who don't know how the scope works.

Because if you have a 1Vpp AC signal superimposed on a 5V DC level, and the oscilloscope set to AC trigger mode with the trigger level at 0.5V; the trigger circuitry will only see the 1Vpp AC signal, and will thus trigger successfully. However, drawing a line at 0.5V on the oscilloscope screen will not touch the curve anywhere. Conversely, if the trigger were set at 5.5V, it would appear to pass through the curve on the screen, but the trigger cicuitry wouldn't activate, given that it is only seeing a 1Vpp signal.

In summary, the line becomes completely meaningless; it doesn't represent anything relevant or useful anymore.

If you're still confused, recall that "AC coupling" (in the vertical/channel menu) and "AC trigger mode" (in the trigger menu) are totally different things. You'll have a hard time understanding what's going on here if you think they are the same thing.

When trigger coupling is AC it do not care vertical DC level. Trigger level setting is relative only with higher frequency signal level. So if signal is example riding on moving DC (very low freq) signal position on the screen is movin g up and down on the screen but we want trig to this higher frequency signal what we are interest and so that it keep this relative trigger level.  Now if we show trigger position marker on the screen right side as when it is if T coupling is DC it do not mean anything exept if we then move it up and down when signal is moving up and down. With different signals this may be very confusing mess.

Here two very poor image quality GIF buth still they show idea. You look them and you can see this principle.

In both cases Signal what we want trig is 3MHz 300mVpp sine. This sine is combined with bit over 300mVpp triangle what frequency is 0.1Hz (100mHz) THis moves 3MHz sinewave signal up and down on the screen.

First GIF you can see two things. When signal fall enough down it loose trigger and after it rise to triggel level it trig.   When level change trigger position in 3MHz signal change and you can see signal shift horizontally when level continue changing.   Trig is fixed to vertical100mV level (DC) because I have set trig level 100mV just for this demonstration.

Next GIF. Only change is trigger coupling. Now it is AC and you can imagine where is trigger position when signal moves up and down. Signal keeps also horizontal position (as long as signal vertical moving is quite slow) because trigger is only relative to this 3MHz signal and it do not care this near DC component. As you can imagine if there is now trigger level marker it also need move up and down. Think if this up and down moving happen with some other frequency...

Trigger level adjusting knob. In trigger coupling DC it set trigger to 50% signal p-p.

In AC mode it set trigger level to signal average (0). If signal duty is 50% average is middle and it is triggel level 0. If signal Duty is near zero also trig position zero is too near signal bottom. My personal opinion is that it is more useful if this 50% button also works also in trigger AC coupling so that it check signal p-p and set this for trigger level so also with very low dyty signals with this button can get reliable trig what user can then change if he want.

Do not care image tresolution. Only look signal  shape and how it moves in different trigger coupling.

I have used this scope after beginning of May. I have  never meet this kind of "feature".
And I have tested it lot. Drop tests on every corner exept front panel, hard break power with random freq, give other person who do not know anything about scopes to do random settings and "monkey" adjustments even these what I do not never do because tens of years knowledge and experience...may reject me to do most stupid things.  Nothing to report but just normally working scope.


But still if there is something... perhaps possible normal front panel button "default" do not default all. Least I do not have checked every single detail.

There is default and security erase function also selectable in menu.

Go to Save/Recall
select Recall
in menu, select type: Security Erase  (it erase all your saved things including what you have defined for front panel default button!! )
then press Recall

then
in menu, select type: Factory Default
press Recall

After it is finished.

Shut off scope

Then turn on.

(there is now chinese language)

Press Utility.
Press language (this read there also with englihs) and select language for you.

Following on from rf-loop.

I don't know why this might happen but I suggest using the default button and start again from the factory settings.

In the future if you don't want to loose your setting by using factory default, you can set your own user defined default settings (Ch's on, 10:1 inputs, Trigger levels, display settings etc) from within the Utility menu.

On the SHS1062, I think most of the strange things are not firmware bugs, could it be a wrong or not connected pin from an IC ? That also gives random faults. This week I planned to change the glass soldered fuse for a sand-filled in decent clips. If I have time I will look for floating pins.

 I decided to buy the scopemeter after I found the problem in a very difficult repair thanks to the logging function of the scope. 
The last days I'm diving in to all possibilities and functions of the scope, I always do that with new instruments. Things that happened:
- I saved two waveforms. Recalled 1 of them  and used it to play with cursors ans measurement values. The scope became very slow in response, the saved waveforms disappeared from memory and then the scope stalled.  The stalling happened when I pressed the scope button while one of the sub-menus was still visible. After rebooting it worked but waveforms are still  gone. Tried to stall it again by doing the same thing several times but no result. Restored to factory settings and everything was fine again.

- A very strange one, I was in playing around a bit in scope mode and by accident pressed a wrong key (I think the scope key) . A menu popped up I have not seen before and I can not find it again. It is only graphics, no text. F1 and F2 are pulseshapes for dutycycle measurements, F3 and F4 are the symbols for rise and fall time measurements.  No values in the menu. Measurement values appeared on the screen not in the F-menu blocks.Then it disappeared, I think I pressed F5 but I'm not sure.

- sometimes screens "merge", it looks like the old screen is not complete erased when the new one appears. Have seen it 3 times now.

- A few seconds after run/stop the trace disappeared. I can not repeat it so again I 1 time event

I'm doing this from memory, I made notes but can not find them. But I do not think it are real bugs. But it is not a good thing. Like it is running under Windows XP  >:D
Strange enough I still like the scope.  ;)

how do you select which channel to display?
This is how most multi-channel scopes work.  Press [Ch1] button and it lights up and channel 1 data/adjustments are shown/possible.  Now press [Ch2] button, channel 1 trace is still visible but Channel 2 data/adjustments are shown/possible.  To go back to channel 1 for adjustments, just press [Ch1] once.  To remove a channel from viewing, make sure that channel has control and then press the [Chx] button - each time you press it the display of that channel will appear/disappear.

Hope this helps.

Based on the full post from k1ttt, I wonder whether he meant to ask about switching the displayed measurement values between channel 1 and 2, not the trace display itself?

If that's the question -- I do not have the scope, but the section titled "Parameter Measure" in the user manual seems to describe this. After pressing the [cursor/measure] button twice, measurement values and channels are selected using the function buttons below the screen. It's described on page 20 and onwards in the manual version I found online, https://mediacdn.eu/m/media/wysiwyg/siglent/Downloads/Manuals/SHS800_UserManual.pdf.

in that manual figure 2-1 on page 6 it shows 4 values that show after you press the auto button.  if you have 2 channels displayed it still seems to show only CH-1 values, except once somehow it switched to CH-2 but we couldn't repeat that.  showing those 4 seems to be related just to the Auto function and they are not displayed like the parameter measurements which are on top of the traces.
