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 18 on page
277
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 260
for a discussion of status register operation.
Figure 9 shows the structure and IEEE 488.2 Common Commands used to access
the Standard Event Status Register Group.
