Calibration Reference B-17
Manufacturing calibration commands
Three calibration steps are only performed at the factory or when the unit has been repaired:
:CALibration:PROTected:AC:STEP14 1V AC at 3Hz
:CALibration:PROTected:AC:STEP15 1V AC at 1kHz
:CALibration:PROTected:DC:STEP0 Rear terminal short circuit
:AC:STEP<14|15>
(CALibration:PROTected:AC:STEP<14|15>)
Purpose To program individual AC manufacturing calibration steps.
Format :cal:prot:ac:step14 <Cal_voltage>
:cal:prot:ac:step15 <Cal_frequency>
Parameters <Cal_voltage> = 1 [1V nominal]
<Cal_frequency = 1E3 [1kHz nominal]
Description The :AC:STEP14 and :AC:STEP:15 commands program the two manu-
facturing AC calibration steps. The appropriate signal must be connected to
the instrument when programming each step, as summarized by the parame-
ters listed above.
Examples :CAL:PROT:AC:STEP14 1 Program AC step 14.
:CAL:PROT:AC:STEP15 1E3 Program AC step 15.
:DC:STEP0
(:CALibration:PROTected:DC:STEP0)
Purpose To perform rear terminal short-circuit calibration.
Format :cal:prot:dc:step0
Parameter None
Description :STEP0 performs the rear short-circuit calibration step in the manufacturing
calibration procedure. Connect a low-thermal short (Model 8610) to the rear
panel input jacks, and select the rear inputs before sending this command.
Example :CAL:PROT:DC:STEP0 Perform rear short-circuit calibration.
