Keithley 2700 Service Manual

Calibration Reference B-15
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 scanner 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>
Parameter <Cal_voltage> = 1 [1V nominal]
<Cal_frequency = 1E3 [1kHz nominal]
Description 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.
Example :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 scanner terminal short-circuit calibration.
Format :cal:prot:dc:step0
Parameter None
Description :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.
Example :CAL:PROT:DC:STEP0 Perform rear short-circuit calibration.
