Error Queues - Agilent Technologies PSA Series Manual

Error Queues

There are two types of error queues, front panel and remote interface. These two queues
are viewed and managed separately. Refer to
characteristics of the Error Queue.
Front panel A summary of the last 11 error messages preceded by an error number
may be viewed in the Error Queue by pressing,
When a remote interface initiates activity that generates an error, the
messages are output to the remote bus. When output to the remote
interface, they are preceded by an error number.
Remote interface
(SCPI) When a user error condition occurs in the analyzer as a result of SCPI
(remote interface) activity, it is reported to both the front panel display
error queue and the SCPI error queue. If it is a result of front panel
activity, it reports to the front panel display error queue, and depending on
the error, may also report to the SCPI error queue.
