Standard Event Status Group
These registers are programmed by Common commands. The group consists of an Event and Enable register. The
Standard Event event register latches events relating to communication status. It is a read-only register that is
cleared when read. The Standard Event enable register functions similarly to the enable registers of the Operation
and Questionable status groups. See
for a description of each register.
The event status register bits are set when certain events occur during instrument operation.
The register is controlled by the IEEE 488 commands *ESE, *ESE?, and *ESR?.
