BTW, anyone has done a calibration/adjustment on SDG2042X?
Run the internal self cal and enjoy your 40 120 MHz AWG.   ;)

Do you experience any improvement after doing the "self cal"?

The service manual says that one should only run self-cal after having done a calibration of the internal feedback channel. But that latter calibration requires Python scripts which, I believe, are unavailable to end users. So, can we run a meaningful calibration?

If the AWG meets the Accuracy and Output Flatness specs listed under Output Characteristics on P8 of the datasheet I leave it alone.

The scripts were available to download from the north american website but Siglent removed them.
Fortunately they are still linked on the chinese site.

Here is the link:
https://www.siglent.com/u_file/download/19_07_18/3b2a90b8a2.rar

Download and save them in case they get deleted.

Just a note to say, took delivery of an SDG2042X, *cough* followed everything in John95's 14-step process *cough* and all worked very well. This was done on FW: 2.01.01.23R8 factory supplied version.
Then verified the performance with a scope = 120MHz goodness.

Then today I did a plain old regular firmware upgade to 2.01.01.35R3B2 and all went smoothly + 120MHz performance still remains.

Posting should anyone find this useful if, like me thought there was a chance of going from a liberated 23R8 to 35R3B2 would reverse the mod... it doesn't appear to.

All the best,
Dan

I had the same experience as you as mentioned in the hack thread. However I found that the peak-to-peak voltage decreases with frequency, soon after 40 MHz.

I've found a bug in FM modulation. With an external 10MHz reference clock, 10MHz output signal, FM frequency of 10mHz, triangle modulation waveform and a frequency deviation of 5mHz the output signal will slowly (a few ns per hours) phase shift in respect to the external reference.

There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Hi guys

I have SDG2042x hacked to SDG2122x, firmware: 2.01.01.35R3B2, hardware 02-02-00-40-00.
Does your SDG2000x copy have the front panel knob working intermittently? I spin for a few seconds and it's ok, then it stops working for a second. The knob doesn't respond at all when turning faster. If this is a software error, it definitely needs to be corrected.

Hi so I just upgraded my spd3303x-e with the FW I found on page 9 from tv84
https://www.eevblog.com/forum/testgear/siglent-ads-firmware-file-format/200/

In 2 weeks I'm getting the SDG2042X. What page should I go to, for the main procedure people have been using, so I can study up ?


As for really learning how this stuff works, and getting into hardware hacking, (I have a BusPirate on the way), what should I do, learn python or some C language ?

I'm buying 1 of these in 15 days if people go to work in Ontario

I can't wait, then I'll try and upgrade it. I could just afford the 2082, but thank Siglent for making either near   my budget.

Assuming you refer to the "upgrade" procedure, this step-by-step list is still current, I believe:

It seems that with the last firmware update I applied, the undocumented LXI SCDP (screendump) command stopped working.  Can anyone else confirm?  I know this used to work because I have lots of screendumps from my SDG2000X.  I use the same program to do screen capture from all of my Siglent devices.

It's not documented in https://siglentna.com/wp-content/uploads/dlm_uploads/2019/12/SDG_Programming-Guide_PG02-E04A.pdf

Can someone confirm whether this was explicitly removed?  There's nothing in the release notes about it.
