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.
Table 4-3 . Bit Definitions – Standard Event Register
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.
