Rigol DP832 - Firmware list and bugs

<< < (151/153) > >>

TurboTom:
There seems to be a new firmware for the DP800 series of PSUs available on Rigol's Chinese web site. Apparently, it's a 00.01.18.00.00 version, released in october 2021. I tried to install it on my DP832 but my PSU refused to work afterwards (initialization appears to work but instrument gets stuck after entry into "operation mode"). Attempting to flash the analog boards didn't show any reaction. Since the file name is "DP800(ARM)update_tcm4-4006.zip", maybe it's meant for a later H/W version of the PSU? Does anybody know what's going on here? Unfortunately, a changelog isn't included in the archive...

I just bought an 832A, and the firmware version from the factory is 00.01.19.00.00.  I couldn't find any release notes as to what this version includes/fixes.  Does anyone have any idea?

I just tried downloading the firmware from the official website (link in post 1). I still got 1.16. What happens if you go to the website and download, will they send you 1.16 or >=1.19? That would indicate some new hardware?

Hi,
new DP832 is also delivered with version 1.19. There is issue with Display settings ... menu items "Contrast", "RGBLum" and "Theme" are missing ...
All other features seem to be OK.

I updated my device from 1.16.0 to 1.19.0 (for what??? |O). The update was successful. But after that, all calibration was completely reset.
It was not possible to manually calibrate the device because all the calibrate points values (voltages and currents) were reset. There were just zeros everywhere.

Fortunately, the device was brought back to life and calibrated using SCPI-commands. First, I recorded all the calibration points for all channels according to VDAC, IDAC, VADC, IADC, then  manually calibrated all the channels.

Do not update old devices to 1.19.0. Provide yourself with an activity for a couple of hours (restoring calibration), there will be no further benefit from this  :D
