Standard Event Status Enable Register (SESER)

To make it possible for any of the Standard Event Status Register (SESR)

bits to be able to generate a summary bit, first enable the bit. Enable the bit

by using the *ESE (Event Status Enable) common command to set the

corresponding bit in the Standard Event Status Enable Register (SESER).

Set bits are read with the *ESE? query.

Example For example, suppose your application requires an interrupt whenever any

type of error occurs. The error related bits in the Standard Event Status

60. Therefore, you can enable any of these bits to generate the summary bit

by sending:

OUTPUT 707;"*ESE 60"

Whenever an error occurs, it sets one of these bits in the Standard Event

Status Register. Because the bits are all enabled, a summary bit is generated

to set bit 5 (ESB) in the Status Byte Register.

If bit 5 (ESB) in the Status Byte Register is enabled (via the *SRE

command), an SRQ service request interrupt is sent to the external computer.

Function of SESR Bits

Standard Event Status Register bits that are not enabled still respond to their

corresponding conditions (that is, they are set if the corresponding event

occurs). However, because they are not enabled, they do not generate a

summary bit to the Status Byte Register.
