Rigol DP832 - Firmware list and bugs
extide:
Yes, that is normal. I recently purchased a DP832 that was shipped with v 1.14 and was able to unlock all options using the post v1.09 codes. I also seem to have newer rev analog boards than I have seen so far on here, 03.02.04.03.02.04, it seems the first set of 3 digits is one of the boards and the second set of 3 is the second board so each board in this case is 03.02.04 -- and the first digit in each set of three refers to the hardware version - and the second two the software version. I haven't seen the first digit ever change on other peoples PSU's when they update firmware but the second two do. it seems like 0x.02.04 is the latest f/w for the analog boards. I bet this is simply referring to the f/w in a little micro controller on the boards that houses the DAC's and ADC's for each board. Guess I will have to pop it open at some point and see what they changed.

haw can i see this menu?? i can only see the first 3 values (model, sn and digital version..)
thanks

I received my DP832 today and noticed something strange. When i have the outputs disabled, but connected to my unfused 10A range of my multimeter, there is a significant current flow, different from channel to channel.
Channel 1: 98mA
Channel 2: fluctuating between -10 and -36mA (see scope shot for waveform on multimeter input, the other two channels are stable)
Channel 3: -17mA
When i select 1mA current limit on all channels and i enable them one by one, only channel 1 drops to 0mA (or i guess 1mA, is in the uncertainty of my multimeter :-) For the other channels i have to set a least 10mV (i don't have the high res option enabled yet) and 1mA to get the expected reading of 0 to 2 mA.
The voltages of the disabled channels are of not so much concern (especially given the cheap nature of my multimeter):
Channel 1: 4mV (off) 3mV (on @ 0V)
Channel 2: -5mV (off) -5mV (on @ 0V)
Channel 3: -1mV (off) -1mV (on @ 0V)
Did anyone observe the same effect, i couldn't find anything mentioned so far but i might have missed it.
My DP832 came with firmware version: 00.01.14.00.03 and analog boards: 03.02.04.03.02.04
