Standard Event Register
The Standard Event Register groups report when any of the 
following events occur: power on, command syntax errors, 
command execution errors, self-test or calibration errors, query 
errors and when the *OPC command is issued. Any event that has 
its corresponding bit enabled in the Standard Event Status Enable 
register is logically summed to set the Standard Event Summary bit 
in the Status Byte Register. The *ESE command can be used to set 
the bit weight of the Standard Event Status Enable Register.
