Manufacturing calibration commands

Three calibration steps are only performed at the factory or when the unit has been
repaired:
:AC:STEP<14|15>
(CALibration:PROTected:AC:STEP<14|15>)

:CALibration:PROTected:AC:STEP14
:CALibration:PROTected:AC:STEP15
:CALibration:PROTected:DC:STEP0
To program individual AC manufacturing calibration steps.
:cal:prot:ac:step14 <Cal_voltage>
:cal:prot:ac:step15 <Cal_frequency>
<Cal_voltage> = 1 [1V nominal]
<Cal_frequency = 1E3 [1kHz nominal]
The :AC:STEP14 and :AC:STEP:15 commands program the two
manufacturing AC calibration steps. The appropriate signal must be
connected to the instrument when programming each step, as summa-
rized by the parameters listed above.
:CAL:PROT:AC:STEP14 1
:CAL:PROT:AC:STEP15 1E3
To perform rear scanner terminal short-circuit calibration.
:cal:prot:dc:step0
None
:STEP0 performs the rear scanner terminal short-circuit calibration
step in the manufacturing calibration procedure. Install an extender card
with low-thermal shorts on the output terminals installed in Slot 1 and
select the rear scanner inputs before sending this command.
:CAL:PROT:DC:STEP0
1V AC at 10Hz
1V AC at 1kHz
Rear scanner terminal short circuit
Program AC step 14.
Program AC step 15.
Perform rear short-circuit calibration.
