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. All of
these conditions can be reported in the Standard Event summary bit through
enable register. To set the enable register mask, key in a decimal value to the
register using the event status enable (*ESE)command.
