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 the 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.

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?
