The standard event register
The Standard Event register reports the following types of instrument events:
power on detected, command syntax errors, command execution errors, self-test
or calibration errors, query errors, or when an
*OPC
command is executed. Any or
all of these conditions can be reported in the standard event summary bit (ESB,
bit 5) of Status Byte register through the enable register. To set the enable register
mask, you write a decimal value to the register using the
*ESE
(Event Status
Enable) command.

NOTE
An error condition (Standard Event register bit 2, 3, 4, or 5) will always record
one or more errors in the power supply’s error queue. Read the error queue using
the
SYST:ERR?
command.
