*SRE and *SRE?

*SRE <mask> specifies which bits of the Status Byte Register are enabled to generate a service request . Event and summary bits are always set and cleared in the Status Byte Register regardless of the enable mask. Mask is the sum of the decimal weights of the bits to be enabled.

The query form returns the current enable mask.

A 1 in a bit position enables service request generation when the corresponding

Status Byte Register bit is set; a 0 disables it.

Comments Executable when initiated: Yes

Coupling group: none

*RST Condition: unaffected

Power-On Condition: no bits are enabled

Example Enable service request on Message Available bit

*SRE 16

Enable request on MAV

*STB?

*STB? returns the value of the Status Byte Register. Bit 6 (decimal weight 64) is set if a service request is pending. STB? should not be used to read the Status Byte register if a service request is generated by a message available (MAV) condition.

Comments *STB? is a query. Thus, sending the command in response to a MAV condition will generate Error -410 "Query interrupted".
