Status Reporting Decision Chart 848
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.
