Calibration Reference C-5
The :INIT command should be sent only once at the beginning of the calibration procedure. Do
not send :INIT before each calibration step.
Example :CAL:PROT:INIT Initiate calibration.
:SAVE
(:CALibration:PROTected:SAVE)
Purpose To save calibration constants in EEROM after the calibration procedure.
Format :cal:prot:save
Description The :SAVE command stores internally calculated calibration constants
derived during comprehensive in EEROM. EER
OM is non-volatile memory,
and calibration constants will be retained indefinitely once saved. :SAVE is
sent after all other calibration steps.
Calibration will be only temporary unless the :SAVE command is sent to permanently store
calibration
constants. Calibration data will not be saved if:
1. Calibration was not unlocked by sending the :CODE command
2. Invalid data exists (for example, cal step failed).
3. An incomplete number of cal steps were performed.
4. Calibration was performed out of sequence.
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 C-1 on page C-3.
Description The :CAL:PROT:STEP<n> command performs calibration at the various
points listed in Table C-2. See Section 14 for details
on test equipment and
connections.
Calibration steps must be performed in the order listed in Table C-2, or an error will
occur.
Example :CAL:PROT:STEP0 14 Perform cal step 0 (Ch. 1 full-scale output).
