Status Reporting Structure
This section describes the status reporting structure used in Agilent 4155C/4156C.
These are IEEE488.2 status structures except for the following:
•
Standard Operation Status Register (for SCPI)
•
Questionable Status Register (for SCPI)
•
Emergency Status Register (for 4155C/4156C)
•
Measurement Stress/Status Register (for 4155C/4156C)
For more information about these non-IEEE488.2 status structures, see "STATus
Subsystem" in Chapter 5.
In general, the status data structure is used to "request service" or indicate a specific
condition (for example, operation complete) via SRQ (Service Request). Note that
the user may be notified that certain events have occurred even if the user did not
request the information.
Refer to the following figures for a model of the status data structure.
