Instrument Messages
Introduction
Event and Condition Categories
The three categories of severity are described below, for both Events and
Conditions.
Errors Error messages appear when a requested operation has failed. (For example, “Detector not available”,
“File not saved”.) Error messages are often generated during remote operation when an invalid
programming command has been entered. (For example, “Undefined header”.)
Some errors are conditions rather than single events. They exist for a period of time, so they have
associated “Detected” and “Cleared” events. (For example, “LO Unlocked” or “External reference out
of range”.)
Error messages appear in the Status Panel at the bottom of the display. A message remains until you
press a key, or another message is displayed in its place.
Error messages are logged in the error queues. If the error is a condition, both the Detected and
Cleared events are logged.
Warnings Warning messages appear when a requested operation has completed successfully, but there are
modifications and/or side effects. (For example, if you requested too high a stop frequency, then
“Data out of range” is displayed and the analyzer sets itself to the highest available stop frequency.)
Some warnings are conditions rather than single events. They exist for a period of time, so they have
a “Detected” event and a “Cleared” event. (For example, if you set the sweep time too fast for a
measurement to meet the instrument specifications then the “Meas Uncal” message is displayed until
you slow down the sweep time.)
Warning messages appear in the Status Panel at the bottom of the display. The message remains
until you press a key, or another message is displayed in its place.
Warnings are logged in the error queues. If the warning is a condition, both the Detected and Cleared
event messages are logged.
