Introduction
The Error and Status messaging system of the Keysight Signal Analyzer reports
events and conditions in a consistent fashion, as well as logging and reporting
event history.
Event vs. Condition Messages
An Event is simply a message indicating that something has happened. Events
are sub-divided according to their severity, into Error, Warning or Advisory
categories. The sub-divisions are described in more detail in the section “Event
and Condition Categories”.
A Condition is a state of the analyzer, which is characterized by a Detection
event and a Clearing event. Conditions may be Errors or Warnings.
Event and Condition messages appear in the Status Bar at the bottom of the
analyzer’s display screen.
