I've been playing around a bit with my SDG805. I don't know if it's been noted elsewhere but I found a serial console on the debug header. You can dump yourself into uboot and dump flash/play around from there. You can also access the SD card. I guess the SD card might be used for flashing the latest firmware versions during production as there's code to flash from the SD card. My notes are here:

Now in the process of reflashing uboot as I hosed the flash! Seems like there are multiple options for de-bricking the AM335x. But if anyone happens to have a complete flash dump knocking around that would be handy.

Oh dear.
A similar thing happened here:

Sorry I don't have the file to help you, maybe another member can pull the files you need.

I've been hacking around trying to recover my SDG805 after hosing the flash. I've now been able to recover my system and my notes are written here:

http://41j.com/blog/2016/08/sdg800-recovering-from-a-hosed-u-boot/

Weirdly after recovering the flash and updating to the latest version it now identifies as a SDG830 and the standard menus go to 30MHz. Not hugely useful considering you can output 30MHz sinewaves etc on the SDG805 using arb mode but kind of interesting.

btw, in the process of trying to recover the system I asked Siglent for the source code of the GPL software used in the SDG805 (including u-boot) they refuse to provide it which is kind of a shame (and a violation of the GPL of course).

Hi all, I purchased a SDG-1025, which has been working nicely. And I have ordered a second hand 82357B USB-GPIB adapter, which is on its way - but I don't even know if I actually need this adapter or not.

My barrier right now is..... I tried to figure out what I need to do for getting the SDG-1025 to work with GPIB. The user manual indicates 'GPIB-optional', but that's about it. I google 'SDG-1025 GPIB', and look for videos or images that could give hints about what hardware is needed (eg. a photo of a cable connection, or a GPIB-adapter connected to a SDG-1025). I wasn't able to find anything like that. I have not found a single photo on the internet (or anywhere) that even shows a SIGLENT device (of any kind) connected via a GPIB interface/adapter etc. Maybe there is something in this.

Then I came across this thread here, which could be really handy.

If anybody has successfully used their SDG-1025 (or SDG-1000 series) to work with GPIB, then could you please point me in the right direction about what hardware I need to buy? In particular, the user manual says 'gpib optional'. Does that mean I need to purchase a hardware GPIB card that needs to be physically installed in the SDG-1025? Or does that mean I can connect the USB end of a 82357B USB-GPIB adapter into the front-side USB port of the SDG-1025, and the other end of the adapter to a GPIB-card (attached to a computer/PC)?

Thanks for any help in advance! Nice to have found this thread in EEVblog.

Hi tautech! Thanks very much for your kind help! That device will be exactly what I need.
This suggests that at least one of the USB ports of the SDG-1025 can connect to the external interface adapter. I'll see if my 82357B adapter (soon to arrive) will work once it gets here. If not, then that siglent USB-GPIB adapter should definitely get me the right path. Thanks very much again! Greatly appreciated.
