And wrong again:
The US use Transcat for Siglent calibration:

As stated in this thread, from nearly a year ago:

If Siglent owners need calibration services then it is best they contact their local Siglent dealer for recommendations as to where this can be achieved. Period.

This thread has just changed my decision to buy siglent gear.
Thanks for your help in staying away from this gear.

Well, well well... I decided to skip going through all the dealers and go straight for Siglent HQ. I got a fantastic response from a really nice guy - Siglent do not use a proprietary .exe "EasyTest" - but a really nice calibration and adjustment suite written in Python with Microsoft Excel documents for the results.
He apologised that there are many prompts in Chinese - this is the exact code that Shenzen use for factory production use after all. Looking at the code there is nothing to apologise for! It's all written in very clear English and nicely structured.
Now it is only written for specific equipment but in a very nice manner that will let you add your own Python equipment library for example. It scans the VISA network and use *IDN? to determine if suitable DMM, Scope and Power Meter are available.
I've asked for permission to publish on EEV. After all, some dealers appear to have a "gatekeeper" attitude and I don't want to step on their toes.
But for providing excellent information for their test gear then I am a Siglent fan again! :-+

Hi all,
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.
