COMMAND REFERENCE
CAL? CALibration
*
Syntax: CAL?
*
Response: 0 | 1
0 Calibration okay.
1 Calibration not okay.
Description:
This query performs an automatic internal self-calibration and reports the result of
that calibration. No external means or operator interface is needed. The response
indicates whether or not the instrument completed the self-calibration without error.
A response of 0 indicates that the calibration executed successfully. A response of
1 indicates that the calibration was not successful.
A possible calibration error is also reported via bit 8 in the QUEStionable status.
If bit 8 = 0, the calibration was successful. If bit 8 = 1, the calibration went wrong.
The CAL? query is the equivalent of the CALibration[:ALL]? query.
*
Limitation:
The calibration process will last a couple of minutes. During this time bit 0 in the
OPERation status is set, indicating that calibration is busy. This status information
can only be requested, if the calibration was started via the front panel. This is
because the CAL? query is a sequential command. So, a next command or
*
query in the same program message is not executed until the calibration process
is completed. Until then, no response to a next query is obtained.
Example:
→
Send *CAL?
←
Read <response>
IF <response> = 1 THEN PRINT "calibration not successful."
Front panel compliance:
The CAL? query is the remote equivalent of the front panel CAL key.
*
Response is held up during calibration.
