IEEE 488.2 defines data structures, commands, and common bit definitions for
status reporting (for example, the Status Byte Register and the Standard Event
Status Register). There are also instrument-defined structures and bits (for
example, the Operation Status Event Register and the Overload Event Register).
An overview of the oscilloscope's status reporting structure is shown in the
following block diagram. The status reporting structure allows monitoring
specified events in the oscilloscope. The ability to monitor and report these events
allows determination of such things as the status of an operation, the availability
and reliability of the measured data, and more.
