The Siglent SDG1000 and SDG800 thread

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.

I dont have original siglent fw dump, but here is file from rebranded unit not old tho, version is 1.01.01.31R1. Maybe editing SN and model inside with HEX editor will work. Just search "SDG1010" inside the file, its clear what to edit. But will it work? no idea.

Got a second hand (no warranty) SDG1025. When I bought it looked like a brand new :) (original box, still in the original plastic bag neatly packed).
Got the latest Firmware (37R2) installed, did the "Self Test" and "Self Calibration", but still have the same problem - there is no signal on any output, just some DC value that I can change changing the offset value, but can't find direct relationship between the offset value selected and offset value actually measured.
And yes, I did turn the CH1/CH2 on :) I only tested Sin Wave, just guessing it will be the same with other wave forms.
Counter does not register anything connected to CH2 either.
I'm getting ready to open the box and check some of test points listed in the Service Manual, but information there is very limited, so I hope some of you on this board can offer some suggestions what to do/try.
Thanks!

I encountered the same problem.
Using the firmware version SDG1000-V00R001B01D01P37R2, after executing the "self-test" command, only square waves can be output with a fixed amplitude, while the other sine waves, white noise, and pulses do not output waveforms.
My model: SDG1020

@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.
