*ESE

This command sets or queries the bits in the Event Status Enable Register (ESER). The ESER is an eight-bit
register that determines which bits in the Standard Event Status Register (SESR) will set the Event Summary Bit
(ESB) in the Status Byte Register (SBR).

Syntax
*ESE <NR1>
*ESE?
Arguments
<NR1> A value from 0 through 255. The binary bits of the ESER are set according to this value.
The power-on default for the ESER is 0 if the *PSC command is set to 1. If the *PSC command is set
to 0, the ESER maintains its value through a power cycle.
Returns
The query form of this command returns a string that represents a binary value ESER. For example,
the *ESE? command might return the string 186, indicating that the ESER contains the binary value
10111010.
Example
*ESE 145
Sets the ESER to binary 10010001, which enables the PON, EXE, and OPC bits.
