LaurentR: I looked quickly at your updated DP832 calibration script and noticed a little problem with it.  On line 135 you reference the variable 'psuIdn' when detecting attached DMM type:

--- Code: ---isDM3068 = ~isempty(strfind(psuIdn, 'DM3068'));
--- End code ---
No doubt it should be 'dmmIdn' instead.

Thanks. There are a few other issues as well that materialized in bson's Python port. My DM3068 guinea pig never materialized, so I'll wait for one to try to make a proper update.

Warning: USB Device broken in 01.14

UPDATE: I re-flashed the 01.14 firmware, and this time no problems!  Ignore below...

After updating to 01.14 I wanted to re-calibrate the unit using LaurentR's MATLAB script (old version :) ) and discovered that my Windows PC would not recognize the DP832 as a USB Device!  As a result Keysight "Connection Expert" (Part of Keysight IO Libraries 17.1) could not find the DP832, and I could not perform any calibration!

I was able to downgrade to 01.13 (thankfully USB Host function is not wrecked!) and USB Device capability came back -- DP832 appeared in Connection Expert and all good.

Interestingly the version notes (posted above) mention USB device library (and LXI + SCPI library) updates in 01.14 release.  In fact, 01.13 also included USB device, LXI and SCPI changes...

Side note: DP832 did not appear in Connection Expert with either firmwares 01.13 or 01.14, although DP832 does get IP address...  Does anyone's DP832(A) using LAN appear in Agilent/Keysight Connection Expert, or the equivalent National Instruments explorer?

Would other people be able to confirm the above findings?  If this is a confirmed problem I will add it to the bug list.  For the moment, it seems must use 01.13 and USB for calibration.

My DP832, firmware 01.14 is still recognized trough USB and LAN under Keysight Connection Expert.

Thanks, OldNeurons!.  Following your positive feedback I re-flashed the 01.14 firmware, and this time no problems for Keysight Connection Expert to detect the DP832 via USB!  A mystery whatever happened the first time...  I have updated my post above.

I tried LAN connection but Connection Expert still does not see it.  Rigol UltraSigma does find it, though, and DP832 responds to SCPI commands that way.

Does anyone control DP832 via LAN connection and have any news about doing so?
