Status Reporting Decision Chart

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.
