Detecting calibration errors
If an error occurs during any calibration step, the Model 2303 will generate an appropriate
error message. Several methods to detect calibration errors are discussed below.
Reading the error queue
As with other Model 2303 errors, any calibration errors will be reported in the error queue.
Use the :SYST:ERR? query to read the error queue.
Error summary
Table B-3 summarizes calibration errors.
Status byte EAV (Error Available) bit
Whenever an error is available in the error queue, the EAV (Error Available) bit (bit 2) of the
status byte will be set. Use the *STB? query to obtain the status byte, then test bit 2 to see if it
is set. If the EAV bit is set, an error has occurred, and you can use the appropriate error query to
read the error and at the same time clear the EAV bit in the status byte.
