Manufacturing Calibration Commands; Ac:step<14|15; Dc:step0 - Keithley 2700 Service Manual

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 man-
ufacturing AC calibration steps. The appropriate signal must be connected
to the instrument when programming each step, as summarized 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
Calibration Reference
1V AC at 3Hz
1V AC at 1kHz
