Rigol DP832 - Firmware list and bugs
McBryce:
If you got the "Installation Fails" message then you've probably put the wrong key in more than 3 times. As far as I can remember, the DP832 will block all license keys now for the next 24 hours, so you'll have to leave it running for a day before you can try the correct key.

Thank You, I guess I tried this Codes for more than 20 times...
I'll report tomorrow.

Hi,
I'm observing some strange behavior on my DP832, FW:1.14. This is the output given from the cal program:

The DAC values seem a little whacky and sure enough, after I calibrate the voltages are spot on but the readouts are way off. It will measure 2.002V when set to 2.000V but the DP832 will read back and display 2.961V.
I haven't written the cal data so restarting brings me back to decent values.
Insights?

Kazam, you don't say what cal program you are using or what your equipment is?
I had similar results when using my (modified) version of bsons python script. I put the issue down to the script not waiting long enough for the PSU to settle after changing its settings, but I didn't investigate as I gave up after encountering the DM3058E bugs (which Rigol have still not fixed).
I just chose not to commit the calibration when I had obviously faulty results.

To clarify:
Using Matlab script posted earlier in thread. modified to use my Keithley DMM7510.
I checked the strings and values manually when debugging the script and it all checks out.
I have tried different wait times between setting the output of the DP832 and reading the voltage back. It makes very little difference and now I'm using 5 seconds. Still getting really weird data.
Yes, I'm not committing any cal data at the end so no harm done. Just annoying! :)
