COMMAND REFERENCE 4 - 15
*
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> Response is held up during calibration.
IF <response> = 1 THEN PRINT "calibration not successful."
Front panel compliance:
The
*
CAL? query is the remote equivalent of the front panel CAL key.
