Calibration Reference B-5
Example
:CAL:PROT:SAVE
Save calibration constants
:STEP
(:CALibration:PROTected:STEP<n>)
Purpose
To perform various calibration steps.
Format
:cal:prot:step<n>
Parameters
See Table B-2.
Description
The :CAL:PROT:STEP<n> command performs calibration at the various
points listed in Table B-2. See
Section 2 for details on test equipment and
connections.
Note
Calibration steps must be performed in the order listed in Table B-2, or an
error will occur.
Example
:CAL:PROT:STEP0 14
Perform cal step 0 (full-scale output).
