What's new? It must be my broken English but I didn't understand much from the release note.

Fixed the problem: The skew of the two ADCs is not accuracy for hardware of 09 version (System Status shows Hardware Version: 09-xx). The other hardware version has no this problem.

Translation: New HW introduced due to component shortages introduced a skew between ADC's that is remedied with this new FW.

Thanks! So my understanding is that it's not necessary for older units. Do you know what serial number onwards by any chance?

Hello,
Thank you for the news !
My SDS1104X-E is 09-06 Hardware Version so I have just downloaded the file, then will upgrade mine 

(but I have not really understood the "skew between ADC" , have I different type of ADC in my model because of the shortages?   )


Edit: Upgrade OK, but the scope has deleted all my settings, so I have reloaded them from the "default" Button where I have saved them  (and have also a copy on a little 4GB USB Stick)
I have done a recalibration after all that, without anything on the input

Maybe, maybe not. However it is clear from the the firmware notes there has been some minor HW change.

This must not happen !
Please list each of the settings types deleted and I'll report this to Siglent.

I have extracted the .xml file from my setting, then re-flashed the FW, then re-extracted the .xml: 120 modified lines (I'm a TotalCommander user , and I have compared the 2 files with it) .
So too much to list I think 
My original .xml is 88591 bytes and after having flashed the new FW, the file is smaller: 88564 bytes.

What I first saw:
>reset of the channels configurations, with the 1rst yellow channel with trace in the middle.
>lost of all the display configuration (intensity/graticule/transparency)
>lost of the AWG configuration with my JDS6600 
>lost of the NTP server (no popup after boot)
...

I have not checked all, as I have recovered all settings with the backup I have made and set on the "default" button

Hi, I just found this big thread.

I wonder if the hobbyist upgrade can be done after the V6.1.37R9 firmware, and where explains the steps to upgrade it.

Thank you.

Thought I'd let you search for a day or 2 only to find your answer was currently on P2 of the TE board:

Thank you so much.  I still can't find it. Maybe a link?

I guess this kind of thread should keep updated the OP with the necessary info or at least an index to the relevant Replies.

I asked where are the steps because I found several times in other threads that the first posts were outdated and just close to the last post I found the correct solution.

Focus only on finding the python method as it’s the safest.

Just received my brand new SDS1104X-E. There's A LOT to read now 

[Minari]

Oooh, OS version 8.3.  Anyone know what features this has over the previous version?  I can't see any reference to minor OS revisions on the Siglent website.

[MathWizard]

I never did update my firmware's yet, on any of my Siglent gear.

I have 2-3 of the default probes, that must have a break in them somewhere, and sometimes the cables lose gnd, and other times just get weird in some positions.


So how hard is it to take them apart, and fix the crack or whatever, and fix it ? I just remembered they are not just ordinary coax.

But if I don't care about cutting 1 open , are they fairly easy to fix, like with solder, and glue, electric tape, maybe even tinfoil

Why not buy a New cheap and good probe?

The calibration certificate indicates that it was calibrated in 21/03/2022 so the OS V8.3 must be at least 3 months old.

Hi there!

I've been fiddling with the SDS1104X-E for quite a while now and I think I've found a bug in the Counter function or, at least, a weird behaviour. For instance, get a couple of sine waves in, say, 1KHz in channel 1 and 10KHz in channel 3. Now start the counter and select channel 3 as its source. The counter displays 1KHz as if it were the channel 1:






I searched the forum and found something in this very topic:

https://www.eevblog.com/forum/testgear/siglent-sds1204x-e-released-for-domestic-markets-in-china/msg3728731/?topicseen#msg3728731

Is anyone using the new counter function?  It appears not to work the way I would expect--it gives you the option of selecting any active channel--and changes the color of the 'Frequency' annunciation to match, but won't actually indicate anything unless the trigger source is that channel.  I'm not sure how that is a helpful feature...

This may address my observations but upon further investigations I found that the Counter function displays the correct answer, 10KHz if I activate any of the other 2 or 4 channels.

Channel 2 also activated = Counter OK:



Now I disengage channel 2 and engage channel 4. Again, counter OK:



It looks like a bug, right?

[pope]

I just followed your procedure and I can confirm that I get exactly the same bug. Thanks for pointing this out! 

6.1.37r8 and OS 8.2

[Calambres]

Ooops!.. I forgot it  my scope is running 6.1.37r9 and OS 8.3

I have an 1104-XE with the latest everything I believe. On the 4 channels 2-3-4 all are within 1 mV of zero with the input shorted gain max. However Ch1 is at +3 mV. I did a self cal and its the same afterwards as before. Is there an adjustment or something I need to do? Is this within tolerance?  Its not very important, however only one channel seems to be afflicted so there may be more to this.

What do you get with the channels open (nothing connected to the scope) ?

[1audio]

No change. I shorted the input just to be sure. I have a Tek THS720 that drifts but the self cal corrects it. I was expecting that here but no success. Has nayone else noticed offset?

Do you mean "gain max" that means you have set channels for 500uV/div.

I have never seen that with this setting channel is +3mV offset. (with this setting +3mV is outside from screen. With 500uV/div whole sceen vertical range is -2mV to +2mV
1mV offset is 2 div. Also this I have never seen exept in chase that selfcal is out of order. (it can also happen if oscilloscope is cal ok in +24 and just after turn on from -20 celsius... during warm up it may of course drift quite lot)

Please do, all next even if you have done it earlier

First turn it on and set it to factory default state (not front panel "Deafault" button). (you can findFactory Default from Save/Recall menu -> Recall -> Type: select from list Factory Default -> Press to Recall)
And then keep all as is.

Keep oscilloscope running alone least 30minute in place where it can reach thermal equilibrium..

Then
NOTHING connected to oscilloscope input connectors. All BNC need be open!

Start Selfcal. Do not touch anything during this and keep all strong EMI sources far away from near inputs, including your fingers.

After it is finished.

Still do not connect anything to inputs. Do not adjust any other things but next
Turn all 4 channels on and set all channels for 500uV/div. All trace positions 0.0V (you can push Position knob or adjust it so that it is perfectly 0.0V)
If real trace is not vertical center do not adjust it to center using Position.

Only just connect USB memory stick and push "print" button for get screen image to USB. (naturally if you allready have PC connected to scope then screen shot using it)

Display this image here so we can see this situation and because you do exactly as asked we also know perfectly what is oscilloscope state when this image is taken.

I did not realize the channel was set for a 10X probe when I sent the original note.

I followed the suggested process which cleaned up the offsets (at least down the the noise level). Picture attached. I'm not sure what had left the offset but its essentially gone. Ch 2 has a little offset but not enough to be concerned.

Good.

Looks very normal.
(Despite the fact that you did it differently than I advised - although in this case it does not cause ambiguity or a problem when the thing to be evaluated is this simple.)

This small dc offset can not compensate - it is  feature in this model. It just need accept. (offset DAC and other circuits limits)
If need do accurate Vrms measurements where DC offset is eliminated then use Stdev or Cycle Stdev instead of DC including RMS or Cycle RMS .

If keep Quick Cal: On (Utility menu) it try some times compensate offset drift when 500uV/div - 2mV/div is selected. 
It do this process also always during first 30minute from power up when it works 15sec intervals. It can easy see that roll resets every 15 second if use slow roll mode and 500uV/div. After around 30 minute from powerup  it stop (but after then it can process if system "think" it need do) 
It is default on. Turn it off only when really need and after then back to ON again.
