Model 2500 Service Manual Calibration Reference B-7
Voltage bias commands
:SOURce
(:CALibration:PROTected:SOURce[1])
(:CALibration:PROTected:SOURce2)
Purpose
To calibrate the active channel 1 or channel 2 voltage bias range.
Format
:cal:prot:sour1 <DMM_reading>
:cal:prot:sour2 <DMM_reading>
Parameters <DMM_reading> = Within ±10% of positive full-range value
0 ±0.1% of full-range value
Within ±10% of negative full-range value
Description The :CAL:PROT:SOUR1 and :CAL:PROT:SOUR2 commands calibrate
the active range of the channel 1 or channel 2 voltage bias source
respectively. During the calibration process, this command is sent three
times for each range, once each with parameters of approximately posi-
tive full range, 0, and negative full range. The voltage parameters are
determined from a DMM reading.
Example
:CAL:PROT:SOUR2 9.9
Calibrate channel 2 10V range.
:DATA
(:CALibration:PROTected:SOURce[1]:DATA)
(:CALibration:PROTected:SOURce[1]:DATA?)
(:CALibration:PROTected:SOURce2:DATA)
(:CALibration:PROTected:SOURce2:DATA?)
Purpose
To set/query channel 1 or channel 2 voltage bias calibration constants.
Format
:cal:prot:sour1:data <Cal_constants>
:cal:prot:sour2:data <Cal_constants>
Parameters <Cal_constants> = ASCII floating point format, delimited by commas
Query :cal:prot:sour1:data?
:cal:prot:sour2:data?
Description The :CAL:PROT:SOUR1:DATA and :CAL:PROT:SOUR2:DATA com-
mands allow you to send channel 1 and channel 2 calibration constants
directly to the unit, while the :CAL:PROT:SOUR1:DATA? and
:CAL:PROT:SOUR2:DATA? queries request channel 1 and channel 2
calibration constants. These commands allow you to alter calibration
directly without having to perform the entire procedure.
Example
:CAL:PROT:SOUR2:DATA?
Query channel 2 constants.
