Giga-tronics 58542 - Event Status Register; Figure 2-9: SCPI Status Structure Registers

2.5.23.1 Event Status Register
The *ESE command is used in combination with group commands that form the meter’s service request
system. These commands and their responses are almost identical to the IEEE 488 (GPIB) SRQ service
request command structures. The *ESE command is used to enable bits of the event status register mask.
The *ESE command is one of the commands that can used to monitor the status of the power meter.
Together with the status byte (also see commands *STB? or *SRE?) and the operation status register
(STATus:OPERation), the event status register provides information on several critical 58542 functions
and error conditions.

NOTE: The logical value in the register is used both to enable a bit’s event function and
to enable that bit of the event status register mask to report the event status (Following
the *ESR? command).
