Status and Events
The SCPI interface in the analyzer includes a status and event reporting system
that enables the user to monitor crucial events that occur in the instrument. The
analyzer is equipped with four registers and one queue that conform to
IEEE Std 488.2-1987. This section will discuss these registers and queues along
with status and event processing.
Status and Event Reporting System
Figure 3--1 outlines the status and event reporting mechanism offered in the
WCA200A Series analyzers.
The status and event reporting mechanism contains three major blocks:
H
Standard Event Status
H
Operation Status
H
Questionable Status
The processes performed in these blocks are summarized in the status bytes.
They provide the error and event information.
