The Standard Event Register
The standard event register reports the following instrument events: power-on
detected errors, command syntax errors, command execution errors, self-test or
calibration errors, query errors, or an *OPC command. Any or all of these conditions
can be reported in the standard event summary bit 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.
