Siglent SDS1104X-E and SDS1204X-E Mixed Signal Oscilloscopes

[sulzer]

A little help for the newbie that I am.
I can't switch to OS3, here is my config:
Software Version : 6.1.37R9
Uboot-OS Version : 8.2
FPGA Version : 1.4
What am I not understanding?
What can I upgrade?
Thanks for your help

it looks like I am not the only one then

What is your hardware version?  I'm pretty sure OS3 is only for 09-06.

Nope!  I've got an SDS1104X-E  with Hardware Version 01-05 and OS 8.3 from factory:

Did anyone measured noise at 500 uV/div full BW 50ns/Div with the newer HW versions?
Just because originally what Performa01 measured it seemed significantly below spec at 63uV RMS (without the DC so in this case std dev) and I got similar values on mine.

Hi folks, got today by SDS1104XE   
It was calibrated in december 2022.

1 probe from 4 have contact issues. I contacted support to ask a newone (w/ a video).

[patrik96]

Hi, may someone able to explain me,
I have SDS1104x-E and there is no AutoSetup menu only the Autosetup button,
If activated the Autosetup it adjust the scope onece and after no adjustment but the AUTOSETUP visible in the left bottom corner on the screen.
So if changing the Amplitude or frequency the scope not follow that. (is it normal? my previous OWON follow the signal)

Correct.
These DSO's are designed with the mind that the operator must be in charge of the scope not the other way around.
Either press Auto Setup again or learn how to master the use of the scope, it's not really difficult but instead very rewarding.

I've got the same scope, same HW/OS versions, half a year earlier than yours and exactly the same issue: one of the probes is having issues with the 1x/10x switch

They are warrantied for 1 year so claim a warranty replacement from your supplier.
It often is possible to capture a screenshot of the fault to support your claim.

I checked on mine and it's not "correct" at least the way I understand.

Yes, after the auto-setup you only have one "go back" button at the bottom but
- Amplitude and frequency do work on mine
- You can press any other button and it will retain the auto-setup settings but take you back to the normal screen.

Are you saying that after running an auto-setup your amplitude and frequency knobs don't work?

Nope!  I've got an SDS1104X-E  with Hardware Version 01-05 and OS 8.3 from factory:

Of course, it's pretty clear from the instructions that OSV3 is "not needed", it doesn't mean it won't work.

Sorry, we're not talking the same thing.
Truth be I rarely ever use Autoset instead much preferring to be in charge of the scope.
When I do use it and normally to show a customer a shortcut to getting some sensible display on the screen but then take over the controls to drive and be in charge of the scope.

For scope newbies Autoset is great however I don't recommend you let it capture you too as the human brain is more powerful than the machine. 

[tony359]

I never use auto-setup either but the OP was asking about it so I turned on mine and checked.

Replying that that's the intended operations of the scope because they are"designed with the mind that the operator must be in charge of the scope" does not really sound as a useful answer IMHO.

I misunderstood patrik96 post at first, but then realised that what he meant was that once the Autosetup button is pressed, it only acts on the current signal input. If you adjust the input signal or alter the timebase or amplitude controls on the scope, it will not adjust for the best display, despite "AUTOSET" being displayed on the screen.

It seems like his previous Owon scope tracked the signal for best display while the Autosetup was still activated, without having to press the button again.

Yes, that's exactly what I took from it too but why would designers have the scope devote resources from just being a scope ? Maybe his meaning was not clear.

Indeed the OWON has this interesting feature called "autoscale", which is separate from the autoset.

https://youtu.be/Wn-WZlTMTkc?t=173

I guess it could be useful for some specific signals. It actually looks nicely implemented on that scope.
Would I use it? Maybe, on some occasions I wished my scope didn't constantly require adjustments when changing signals. One scenario I'm thinking about is when I cannot physically reach out to the scope because both my hands are holding probes/boards/wires. Most of the time I would like to be in control of course.
It is useful? In some cases, why not.
Does it work with everything? I guess not, a random digital signal would probably confuse the algorithm.

What I have to disagree with is the "it's always been like that so it's ok" mentality, sorry.

So to answer Patrik96, the answer is NO, the Siglent does not have that feature. To be fair, I believe most of the scopes on the market don't have that, so kudos to Owon )

Yep. Been in that situation many times myself.

Not that long ago I had a board with multiple momentary push switches. I was trying to monitor the pins on an IC while activating various switches. Nowhere to hook the scope probe onto, so could have done with either 3 hands or an autoranging scope to keep the various waveforms on screen.

Micsigs have it. My $35 mini-scope has it. They both work really well when you're poking around without knowing what to expect.

i made a video and shared it

upd: you single touch the cable and see trash on the screen. On 1-2-3-4 channels no matter where.
here is a video, 2 probes (good yellow) and no-label cause doesn't work. https://drive.google.com/file/d/1nDdjzDeuri6OztLnyysLr8ISGFqp_2tj/view?usp=sharing

So i asked them to put new probe in my next delivery they will send me (i paid an AWG also but they will be deliver it in beg of may only :/ ).

Wonder what this firmware does? It's not included in the release notes.

[807]

It has been added to the siglentna site release notes though...

2023/3/27  6.1.37R10  1.  Optimized VGA configuration

[Neutrion]

It's the amplifier not the display I suppose, but still, is there any chance that Siglent start to optimize the ERES feature? Performa01 mentioned in his test that something in the display interface could be optimized, so I wonder whether we could have maybe a better math trace on a lower bandwith or some similar improvement to really get some extra bits. Maybe with fast changing gain levels or something? Not sure how could that be realized, but sometimes it could be really useful. And also the rival Rigol could not go anywhere near to it because it's much lower quality frontend.

Hi, I'm facing a few problems with the 1000X–E I2C decoding capabilities. Maybe I'm doing something wrong, but when monitoring the SCL and SDA channels, I only get partial data segments. I'm watching I2C communication between an Arduino UNO R3 and an I2C LCD on the address 0x27. The trigger I use is for Serial / I2C 2.5V thresholds on both channels and triggering on the 7bit data type with an explicit address of 0x27 and Write bit.

The Arduino refreshes the screen in every 1s, cycling through data, and the scope triggers in every second as intended. It shows the right amount of messages, but the data payload does not seem to be alright. If I use Hex type outputs, it only shows one byte like 0x09, the ASCII corresponds to it as well, but the data does not seem to match the display itself.




One other issue is with the triggering. Even if I trigger at the 0x27 address, sometimes, with bigger sample rates, I get all kinds of data and it does not use the triggers. Also attached a picture of this state, where it clearly shows an address 0x48, what is clearly should be out of scope.



What am I doing wrong? Is it a limitation/bug with the scope?
