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 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 bits 2, 3, 4, or 5) will always
record one or more errors in the function generator’s error queue.
Read the error queue using the
SYSTem:ERRor?
command.

The function generator tried to read the output buffer
but it was empty. Or, a new command line was
received before a previous query has been read.
Or, both the input and output buffers are full.
A self-test or calibration error occurred (see error
numbers 501 through 857 in chapter 5).
An execution error occurred (see error numbers
