request is issued whenever the specified event has
occurred
Range of n: 0 - 255
*ESE?
Standard Event Status Enable Sets the Standard Event Status Enable Register. A service
request is issued whenever the specified event has
occurred
*ESR?
Standard Event Status Register Returns the value of the Standard Event Status Register.
The value returned is a decimal value representing the
current state of the Standard Event Status Register
*IDN?
Identification Returns the instrument identification
