Service Request Enable Register

The Service Request Enable Register lets you choose which bits in the Status Byte Register

trigger a service request.

*SRE <data> <data> is the sum of the decimal values of the bits you want to enable except

bit 6. Bit 6 cannot be enabled on this register. Refer to Figure 3-1 on page 103

or Figure 3-2 on page 104.

Example: To enable bits 7 and 5 to trigger a service request when either corresponding

status group register summary bit sets to 1. Send the command *SRE 160

(128 + 32).

Query: *SRE?

Response: The decimal value of the sum of the bits previously enabled with the

*SRE <data> command.
