SDG800 series FW update:

I recently bought a Siglent SDG805 off Ebay as a Parts/ Not Working item. The description said it was a warranty return from Amazon with the seller being a warranty trans-shipper. As it was cheap and shown powered up I took a punt.

Upon receiving the 805 I booted it up to find that all output waveforms seemed fine but voltages were low.  However it was inconsistent, it was ~3dB down as set voltage increased until the output voltage remain fixed, regardless of further increases in the set voltage. Then a relay would click and the output voltage would jump by about 50% and the process would start over again. This was the case over the entire output range,  :-//  A quick look inside showed no obvious faults and power rails I assumed were good at +/- 5 and 15 volts.

Manufacture date is indicated as 3/14.

Hardware version:      02-00-00-05-00

Firmware version:      1.08.01.08

Before I got too carried away poking around inside  I decided to upgrade the firmware to the latest 1.08.01.11 version. The upgrade instructions say firmware versions 1.08.01.06, 1.08.01.07 and 1.08.01.08 need to install a transition firmware first but no amount of fiddling, USB stick reformatting or attempted firmware roll-backs would convince my machine to install this transition firmware. Eventually I decided to install the 1.08.01.11 firmware as is and hope for the best.

This firmware installation was as straightforward as I had originally hoped for. After a reboot I dove into the Utilities menu to run the re-enabled Self Calibration function. After this was finished the output voltages are now in spec without any pauses or jumps. I have no idea how it could have gotten so far out of cal but hey, at least its fully functional now.

What's more, my machine now seems to believe that it is a SDG830!  ;D


About 2 mins at infinite persistence.


Anyone with an SDG 805 or 810 who wants to confirm that Siglent have taken a leaf out of Rigol's book?

Well looking at the system info pic, at some stage somebody has installed LeCroy Wavestation FW.

As you are not the original owner, who knows what  :-/O have been applied before you got it.
You also may not be aware that Siglent have been incorporating BW upgrade functionality in much of their equipment but as yet have not offered this as a purchasable option, but I do wonder if this is intentionally providing a path for future cracks of Siglent equipment.  :-//

All that aside, you did well......enjoy.  ;)

Heh, I never noticed that Wavestation tag. That may explain it being out of cal as I dont think they ever released a 5 MHz AWG.
