The Siglent SDG1000 and SDG800 thread
czorgormez:
@tautech yes exactly, i tested all functions before firmware flashing. it was ok.
@tv84 i flashed "SDG1000-V100R001B01D01P31.ADS" the result is same :
- in sinus mode, no output ony 5V dc offset
- in square mode, i have some weird signal. the frequency is ok but amplitude is constant and when i adjust under 1 volt, the wave goes negative. i also don't have any other arb waveforms on both channels.

I could try to make a change in the v27 for you to try flash but I think is a long shot... don't have any assurance it would flash, let alone work correctly...
Maybe only tautech could do some magic although I think Siglent won't support any of this...

Already looked, we/I don't have recovery packages for these older SDG1000 models.
Never heard of a update wrecking a product but as these are a age now and maybe don't have the upgrade protection of later models I guess it is possible.
That's why I earlier stated:
I advise you dig deep into the firmware revision PDF in every FW download package as there might be a need for a sequential upgrade path...........

My opinion goes in this direction:
I think besides the BF programming, there might be a CPLD on the device that requires also to be programmed and maybe these Siglent packages don't contain that part. So, now, there is an inconsistency between BF contents and other CPLDs content...
This is based on old (scope) analysis and I'm not sure it applies here but... only Siglent knows.
The best solution would be to flash the device's original brand FW (although it could be one of those very old Siglent versions). If anyone has one that he could dump... although not an easy task.

Yes, quite. I do have OEM FW right back to 2015, maybe earlier only had a quick look.
czorgormez, do you know the version installed before you had all this bad luck ?
