B-10 Calibration Reference
:STEP2
(:CALibration:PROTected:DC:STEP2)
Purpose To perform front terminal open-circuit calibration.
Format :cal:prot:dc:step2
Parameter None
Description :STEP2 performs the open-circuit calibration step in the comprehensive cal-
ibration procedure. Disconnect all cables and accessories from the input
jacks before sending this command.
Example :CAL:PROT:DC:STEP2 Perform open circuit calibration.
:STEP3
(:CALibration:PROTected:DC:STEP3)
Purpose To program the +10V comprehensive calibration step.
Format :cal:prot:dc:step3 <Cal_voltage>
Parameter <Cal_voltage> = 9 to 11 [V]
Description :STEP3 programs the +10V DC comprehensive calibration step. The allow-
able range of the calibration voltage parameter is from 9 to 11, but 10 is rec-
ommended for best results.
Example :CAL:PROT:DC:STEP3 10 Program 10V step.
:STEP4
(:CALibration:PROTected:DC:STEP4)
Purpose To program the -10V DC comprehensive calibration step.
Format :cal:prot:dc:step4 <Cal_voltage>
Parameter <Cal_voltage> = -9 to -11 [V]
Description :STEP4 programs the -10V DC comprehensive calibration step. The allow-
able range of the calibration voltage parameter is from -9 to -11, but -10 is
recommended for best results.
Example :CAL:PROT:DC:STEP4 -10 Program -10V step.
