Calibration Reference
Current measurement commands
:SENSe
(:CALibration:PROTected:SENSe[1])
(:CALibration:PROTected:SENSe2)
Purpose
To calibrate the active channel 1 or channel 2 current range.
Format
:cal:prot:sens1 <Cal_current>
:cal:prot:sens2 <Cal_current>
Parameters
<Cal_current> = 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:SENS1 and :CAL:PROT:SENS2 commands calibrate
the active range of the channel 1 or channel 2 current measurement
respectively. During the calibration process, this command is sent three
times for each range, once each with parameters of approximately
positive full range, 0, and negative full range. The appropriate
calibration current must be applied to the channel 1 or channel 2 input
terminals.
Example
:CAL:PROT:SENS1 1.9e-3
Calibrate channel 1 2mA range.
:DATA
(:CALibration:PROTected:SENSe[1]:DATA)
(:CALibration:PROTected:SENSe[1]:DATA?)
(:CALibration:PROTected:SENSe2:DATA)
(:CALibration:PROTected:SENSe2:DATA?)
Purpose
To set/query channel 1 or channel 2 measurement calibration constants.
Format
:cal:prot:sens1:data <Cal_constants>
:cal:prot:sens2:data <Cal_constants>
Parameters
<Cal_constants> = ASCII floating point format, delimited by commas
Query
:cal:prot:sens1:data?
:cal:prot:sens2:data?
Description
The :CAL:PROT:SENS1:DATA and :CAL:PROT:SENS2:DATA
commands allow you to send calibration constants directly to the unit,
while the :CAL:PROT:SENS1:DATA? and :CAL:PROT:SENS2:DATA?
queries request calibration constants. These commands allow you to
alter calibration directly without having to perform the entire calibration
procedure.
Example
:CAL:PROT:SENS1:DATA?
Query channel 1 constants.
