9.4 Status Register System & STATus Subsystem

In addition to the Status Byte Register, the status byte group also contains the

"Service Request Enable Register" on page 2582, which lets you select which bits in

the Status Byte Register will trigger a service request.

Service Request Enable Register

Enables the desired bits of the Service Request (SRQ) subsystem.

Send *SRE <integer>, where <integer> is the sum of the decimal values of the

bits you want to enable plus the decimal value of bit 6. For example, assume that

you want to enable bit 7 so that whenever the standard operation status register

summary bit is set to 1 it will trigger a service request. Send the command *SRE

192 (because 192 = 128 + 64). You must always add 64 (the numeric value of RQS bit

6) to your numeric sum when you enable any bits for a service request.

*SRE? returns the decimal value of the sum of the bits previously enabled with *SRE

<integer>.

This register presets to zeros (0).
