Rigol DP832 - Firmware list and bugs

<< < (117/153) > >>

core:
Good idea, I will replace ch2 and ch3 on/off LEDs in order to match the display  :-+

Sparky:
I updated the first post with official version for firmware release 1.16 (and removed the download for the beta).

I don't have a DP832 power supply at the moment so I'm unable to test resolution of any further issues.  Please reach out and let me know if there'a anything further needs editing in first post.

Best,
Sparky

Hello gents,

It looks like the manual calibration process is broken again in the new 00.01.16.00.02 update. The bug is readily apparent when performing the ADC-V routine upto the 5V calibration step on channel 1. But even just calibrating the DAC-V borks the output... Tested on both channel 1 and 2. Wow Rigol, just wow.

Also, if you are updating an older unit like I did, the new 01.09 boot loader is not included with the new update provided via www.rigolna.com.

You will have to create an account on int.rigol.com and download version "00.01.16.00.02" there, which is actually version 1.14 but thankfully contains the new boot loader. QC at Rigol is at an all-time low...

As for good news, I got the DP832A connected via telnet at port 5555 and my Tektronix DMM4050 also works via telnet at port 3490. And since I don't have Matlab, LabView or understand Python (I want to learn it, but its syntax is really weird), I plan on writing a new script in Java using telnet rather than RS232, USB or LXI. If there is any interest in the new script let me know and I'll upload it to the forum.

Well time to start coding. Hopefully I can get this SOB PSU working again.

DMM4050 should have a 34401 SCPI emulation mode or be straight compatible, so one of the existing python scripts will work. I highly recommend using it.
Also mentioned in one of the threads here is that with SCPI calibration, you can get more points than with manual cal, so its a better option in the end.
But yeah, sucks to be stuck with it non-functional for the moment.

The DMM4050 does have a 34401 emulation mode, but I believe the Python code uses either the serial or GPIB bus for the DMM, as the 34401 doesn't have ethernet. So I'd still have to poke around to get the Python code to work with my setup, as I don't have a USB-A port on my new laptop (only thunderbolt 3 and USB type C) to connect a serial or GPIB adapter. And ironically enough, my desktop PC's own power supply just gave up the ghost as I was writing the new script. (It seems the power supply gods have found me wanting.) The old Seasonic PSU has to be eight years old or so by now. I'm hoping it has the 10 year warranty so I can RMA instead of spending $$$ on a new one. At any rate, I think it'll be fun to play around with the telnet access, which honestly seems easier than messing with USB to RS232 or GPIB adapters and figuring out LXI.
