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.
