Error Queues - Agilent Technologies ESA-E Series Programmer's Manual

Error Queues

When a user-error condition occurs in the instrument 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 may also report to the SCPI error queue depending on the error.
These two queues are viewed and managed separately.
