B-8 Command Reference
:DATA?
(:CALibration:PROTected:SENSe:DATA?)
(:CALibration:PROTected:SOURce:DATA?)
Purpose
To request the calibration constants for the active range.
Format
:cal:prot:sens:data?
:cal:prot:sour:data?
Response
Four comma-separated ASCII floating-point constants.
Description
The :CAL:PROT:SENS:DATA? and :CAL:PROT:SOUR:DATA? queries
request the calibration constants for the active range of the sense and source
functions respectively. The four returned constants are in ASCII floating-
point format delimited by commas.
Note
To request the appropriate constants (1) select the source or sense function,
(2) choose the desired range, and (3) send the desired :DATA? query.
Example
:SENS:FUNC ‘VOLT:DC’
Select DC sense function.
:SENS:VOLT:DC:RANGE 0.2
Choose 200mV range.
:CAL:PROT:SENS:DATA?
Request cal constants.
