4.5.3 Read and Set Event Status Enable Register

This command programs the Event Status Enable Register (ESE). The programming determines

which events of the Event Status Register (ESR) set the Event Status Bit (ESB) of the Status Byte

events of the ESE are logically OR’d to cause the ESB of the STB to be set.

Command Syntax: *ESE <NR1>

Example: *ESE 255

Query Syntax: *ESE?

Return Parameter: <NR1>

or by *CLS.

Query Syntax: *STB?

Example: *STB?

Return Parameter: <NR1> (Register value)
