4.37 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.
