Standard Event Status Register Group

The Standard Event Status Register Group is a specific implementation

of the status register model described in the Status Register Structure

Overview section. The conditions monitored by the Standard Event

Status Register Group are defined by the IEEE 488.2-1987 Standard.

The Standard assigns specific Test Set conditions to specific bits in the

Standard Event Status Register. Table 6-3 on page 138 details the

Standard Event Status Register bit assignments and their meanings.

The Standard Event Status Register Group is accessed using IEEE

488.2 Common Commands. The Standard Event Status Register Group

includes an Event Register, an Enable Register, and a Summary Bit.

Refer to the “Status Reporting Structure Overview” on page 121 for a

discussion of status register operation. Figure 6-7 shows the structure

and IEEE 488.2 Common Commands used to access the Standard

Event Status Register Group.
