Rigol DP832 - Firmware list and bugs
Gandalf_Sr:
I attempted a Cal of my DP832(A) today with my Keysight 34461A, it failed and I Ctrl + C'd out. The output is attached in .txt file.
I tested that I could run telnet commands to the 34461A on port 5024 and I was getting response to *IDN? but the readings don't seem to be working. When my Cal run started, the screen of the 34461A went blank and it beeped, it that normal? Any idea what's wrong?
Gandalf_Sr:
I'm going through the dmm.send commands around line 350 and trying them out in Telnet, they clearly don't all work. So far, syst:rem and
volt:dc:filt:dig on
generate errors on the 34461A
As expected, the Cal for Ch1 is hosed.
Gandalf_Sr:
So I went through all the scpi commands and modified a few (code attached, zipped) but the results are the same :(
When the code runs, the powershell display is as follows...
Please connect DMM voltage input to ch1 output of PSU
Enter 1 to begin automated voltage calibration
1
ch1 DAC-V calibration
step 0, cal point: 0.2v, meas val: 34461A> 1
step 1, cal point: 0.5v, meas val: 34461A> *opc?
step 2, cal point: 1.2v, meas val: 34461A> *opc?
step 3, cal point: 2v, meas val: 34461A> *opc?
step 4, cal point: 3.2v, meas val: 34461A> *opc?
step 5, cal point: 4.1v, meas val: 34461A> :fetch?
Then I Ctrl + C'd out
The DP832 seems to be setting the voltages but comes up with an 'Incorrect Command' Error
I am only editing the TelnetCal.java file, compiling both .java files, and then copying them to the compiled directory.
My instruments are wired but my PC is running wireless.
Any ideas what's wrong?
Gandalf_Sr:
:wtf: Now I'm trying to do a manual Cal and first trying to go through V DAC calibration and all the fucking values on my meter are -0.231XXX volts! I tried it several times.
|O
I can get out to the normal screen and enter values like 2V or 20V and something rouglhy similar appears but it's way off.
So now I'm stuck with it being way off and no way to calibrate it at all.
skander36:
Yeap !
This I was getting my self , because script erase all cal data at beginning . - psu.send(":calibration:clear "+ch+",all"); // clear all cal constants
The source still can be calibrated manually - its awfull ... you need to insert by hand SCPI comands and values .
