@StillTrying,

not sure but there is no difference if taking a singe shot as well as
running in auto mode.
So from this point I would doubt that there is a AC floating effect.
But to be on the save side I will do the measurement again tonight.
The only point that I could imagine is that my sig gen SDG6022X
have had on dc offset while doing my tdr tests - so I have to
verify it again. But I have used default values (impuls sig) and
changing only duration and no dc offset.
I will keep you informed on my results tonight.

@tautech,
@all,

sorry - I have confirm that I had made an wrong adjustment on my sig. gen.
SDS6022X when doing my TDR measurements.
The observed offset mentioned above was ingested by the peak-2-peak
configuration instead of high/low level configuration where low should be zero
voltage.
That's an issue that should be taken into account when using the waveforms
sinus, triangle or rectangle and changing to puls waveform later.

So "mia culpa" ;-)

As you mentioned above - it's a mandatory thing to know his measurement device.

What's concerns the period/frequency value displayed during measurement mode,
I could confirm too, that my HMO scope behaves in the same manner, so you are
again right.
Yesterday I was not able to check this on the very old HP54503A as promised due
to an config nvmem error that prevent my device from booting.
I use it very seldom and It's now laying around for months unused.
I have to change the battery buffered config ram device  DS1230. Hoepfully finding
one.

So thanks for your explanation and patience.

Until next issue.

Btw. I forgot to upload the orig FW to check the other issue written about.
Will check that on Friday. Today night I'm offline ond off ;-)

I just purchased an SDS2304X scope from Saelig. It included the promotion for MSO, AWG and serial decode if you buy the logic probe (everything but power analysis).

I just turned it on and all of the optional functions are listed as 30 day trial. I didn't find any paperwork with the scope, saying anything about the options, other than the invoice listing them.

Will these options turn permanent after the 30 days, or am I supposed to do something to turn them on?

The installed firmware is 1.2.2.2 R10. Is this the latest? Edit: Looks like it is the latest.

[GregDunn]

Someone will need to provide the license codes to you.  Otherwise the options will expire at the end of 30 days.

You need contact Saelig ASAP and inform them of their error.
Each option has its own license and you should get an authorization code for each that you go online with to the Siglent license website and select model, option and code into and it generates the license specific to your scope.
The website link is contained in the pdf with the license authorization code. IIRC it's a clickable link.
Each generated license then offers a printable sheet with the instruction of how to install so you can have a hard copy at the scope when you do it.

NOT true !
Trial options are free for 30 uses 'of the option' for the DSO's.

The SSA and SVA trial options are timed, ie. they count down based on ON time.

[mojoe]

Thanks. I just emailed Saelig.

[tautech]

Thanks. I just emailed Saelig.

Cool, please report the outcome.
FYI, I've PM'ed users Saelig and rickv14623 to bring this oversight to their attention.

BTW
They may not have had the option authorization codes on hand and have to get them from Siglent America but there should've been indication of this in your sales documentation. It could be all in hand and just you the buyer left out of the loop.

[saelig]

Thanks. I just emailed Saelig.

Got your e-mail and I just replied. The license codes need to be generated and provided by Siglent directly and then we send them along to you. With the free trials to the software we always aim to get the hardware out to customers ASAP. We're contacting Siglent right now to make sure your codes are on their way so we can get them to you right away.

[mojoe]

Still waiting on codes.

[tautech]

Still waiting on codes.

They're coming.
Had a PM from Nate at Saelig just this morning.....he's onto getting them to you.

[mojoe]

And still waiting. They must be creating these codes on stone tablets, by hand.

New Firmware for SDS1202X-E http://old.siglentamerica.com//USA_website_2014/Firmware&Software/firmware/SDS1002X-E_1.3.23_EN.zip

1.  Changed the displayed system information screen. From
ADS  version  of  1.3.23,  the  info  screen  now  shows  5
sections  of  software versions, including the OS version
ID.
2.  Added SCPI commands for Math waveforms (except FFT).
3.  Optimized  accuracy  of  horizontal  measurement,
especially  when  there  are  only  a  few  samples  in  very
small timebase.
4.  Added ability to disable one direction of the full duplex
encoders.
5.  Any arbitrary probe factor from 1e-6 to 1e6 can be set by
universal knob.
6.  Attenuation  and  invert  indicator  were  added  into  the
channel tab.
7.  There  are  some  times  of  quick  calibration  during
warming up the SDS XE. Added a menu below Utility to
disable the quick calibration so that the sampling can’t
be interrupted.
8.  Added SCPI to set up gated measurements on an SDS XE
scope and return the data.
9.  Supported exiting the on-screen keyboard by OK button.
10.  Fixed  the  bug  related  to  displaying  long  IC2  decoded
packets.
11.  Fixed  the  channel  inversion  bug  when  changing
timebase from 1ms to 2ms
12.  Fixed the bug: The setting of Educational mode can’t be
saved after power off.
13.  Fixed the bug: I2C address to 0x3F and the fist byte to
0x8C -trigger does not work
14.  Fixed  the  bug:  The  I2C  trigger  condition   "7  bit
Address&Data"  does  not  work  when   the  payload
contains only a   single byte.
15.  Fixed the bug: Looks like SDS1202X-E does not discard
incomplete bytes in the payload although they are easily
detectable.
16.  Optimized  decoded  data  of  I2C  and  got  rid  of  suffix
‘H’ and ‘A’.
17.  Fixed the bug: There is offset with Channel coupling of
GND.
18.  Fixed the bug of failing to save Pass/Fail mask to U disk.
19.  Fixed the bug: Save data as CSV , but the data does not
account for the vertical offset of the data.
20.  Fixed  the  bug:  The  binary  block  returned  by  the
WAVEFORM command contains the length of the block
in the “#9” header. This length is incorrect when the
NP option of the WFSU command is  used; the header
then gives the memory depth instead of the actual size of
the block.
21.  Fixed  the  bug  of  response  from  the  WAVEFORM
command prefixes the binary block with the string "ALL,"
even when "CHDR OFF" is used.
22.  Optimize self-calibration for channels.

Just updated my scope. Everything works fine

I got an SDM3065X and want to calibrate it. The software EasyTest is nowhere to be found. I have mailed Siglent HQ, only silence so far (4weeks). Are Siglents official policy not to let users calibrate their meters?

I will not specify why I want to cal my meter, I just want to have the ability to do so. This is to void all questions if my meter is out of spec or not, since it's not relevant to my question.

Cal procedures/commands for equipment from other vendors is readily available.

Has anyone got better luck than me?

At this time there seems not to be a English service manual for SDM3065X available so we can't be sure of the Cal process. There may or not be scripts needed for EasyTest and the 3065X may not follow the Cal procedure in the SDM3055 service manual.
Currently HQ is on Autumn break so there's no tech support available until next week.
So for the meanwhile all you can do is check your 3065X meets datasheet spec as a verification of its accuracy.

I have seen segments of a Chinese service manual so I know one exists and in time it will be translated and put online.

Did you get a Cal cert when it was new, it lists the calibration equipment used at the factory.
I have one for mine if you need that information.

I think the only versions available are the "L" versions. Never saw the 5.7" ones.

[PAYY1]

Hello! Thanks for the reply. These are the first models. A part of the flash memory has been spoiled. The device does not start at all. Would have been a dump without a problem would have done. I wrote the answer to the manufacturer.

Some old units would boot freeze randomly and the remedy was to press Math repeatedly at boot.
Try several times if not successful initially.

[PAYY1]

Thanks for the answer. Yes I tried this solution but did not help. Dismantled the flush and sewed the firmware from the 7 inch oscilloscope. Now the device is loaded but the image is not synchronized. Native firmware is saved but with it there is no launch.

I'd like to ask a question or two about the SDM3045X multimeter.

Can it use Relative mode when displaying AC volts as dB?

Can it use Relative mode when displaying AC volts as dBm?

I'm thinking about audio path alignment using sine wave test signals.

In other words, can I set my DUT to whatever the initial conditions are, read the value in either dB or dBm, and then engage Relative mode to make the meter read 0?

Thank you.

I'm not answering for Siglent Support, but I just happened to have my SDM3045X in front of me as I read this, and I was able to use relative mode in both situations.  In the math functions db/dbm menu you can set a reference value.  For dB you can measure or enter a reference and use relative mode from that, and for the dBm function you can enter the reference and use relative mode from that.

Thanks Bill for checking for me as with only a 3065X in front of me I wasn't sure it had the same UI.

Here's a SDM3065X screenshot although you need enter into another menu to capture it so loose capturing the dB and dBm options.
Open leads on the bench:

Hello, I have purchased a SDS1204X-E 4CH oscilloscope and I have the following problem:

I place a 36 MHz 3 cycles burst in channel 1 and everything works ok until I enable channel 2. In that moment the trigger becomes erratic, randomly jumping between the first and the second edge of the signal.

The problem coincides with the fact that the oscilloscope changes the sampling rate from 1 Gs/s to 500 Ms/s when I enable channel 2.

The same happens when I have only channel 1 enabled (1Gs/s) but the signal has more than 72 MHz.

You can see the problem here: https://youtu.be/stSIxn6YvJU

I updated firmware from SDS1004X-E_6.1.25R2_EN to SDS1004X-E_6.1.26_EN and the problem persits.

best regards,
