The Standard Event Register
The Standard Event register group reports the following types of events:
power-on detected, command syntax errors, command execution errors,
self-test or calibration errors, query errors, or the *OPC command has
been executed. Any or all of these conditions can be reported to the
Standard Event summary bit through the enable register. To set the
enable register mask, you must write a decimal value to the register
using the *ESE command.
