Keithley 2420 Current Source
I have some hard time trying to figure out what the right codes are for Keithley 2420 current source to output Custom Sweep value @ 1500mA, # of Points: 4 to sweep. Does any one have experience with this instrument and willing to help? Thanks.
9.003 SCPI [@2420] SOURCE:FUNC CURR;:SENSE:FUNC:OFF:ALL
9.004 SCPI [@2420] SENS:FUNC:CONC OFF
9.005 SCPI [@2420] :OUTP:STATE OFF
9.006 SCPI [@2420] SENS:CURR:NPLC 0.9
9.007 SCPI [@2420] SOURCE:DEL 0.00236
#command below set the Sweep Type to Custom?
9.008 SCPI [@2420] SOURCE:CURR:MODE LIST
#command below set the custom # of points to 4
9.009 SCPI [@2420]sour:list:curr 0,0.05,0.05,0
And I can't find anywhere in the manual to set up the Configure->Sweep->Type->Custom->Init-> Value: 1500mA
The next question is later in the test set up, I'll have to set # of Points for sweep to 20 and then 80. My early line# 9.009 won't be able to contain 80 points in there. What's the solution? Some Calculate math statement from the Keithley instrument? Or from METCAL? And how to wrestle this problem?
