I know this blog is olddd
But I need some help. I got my hands on the 66309D model of this supply with some eeprom corruption problem (The DVM measure were not accessible) so I clean the EEPROM loosing calibration but that is not a problem for me. Unfortunaly doing so I also lost my SN and option.
I see in this video of keysight
around 1:49 there is a DIAG:SN option to set the SN via GPIB.
I try to write a script but is failing saying it is not liking the serial number format. Apparently it expect something that is not text for parameter?
I am new at pyvisa so maybe I am doing a stupid mistake?
First enable calibration
foundInst.write(":CAL:STAT 1")
# Send the serial number, it must be sent as ascii
foundInst.write(f":DIAG:SN US39071080")
# Save calibration
foundInst.write(":CAL:SAVE")
# Disable Calibration
foundInst.write(":CAL:STAT 0")
# Close the instrument.
foundInst.close()
Returned error is -148 that for the user manual is: -148: Character data not allowed
Now are there a way to also enable option?
Because I lost both output as I have the option 521 installed so the output are switched using mechanical relays and of course now the isntrument things it has no option so it never turn on the output. (I verify with a multimeter following the SM that the output rails have the correct voltage!)
