Syntax:

SERVICE REQUEST ENABLE REGISTER
table below, except bit 6
cannot be programmed.
Function:
Programs the Service Enable Register to determine which events of the Status Byte Register will
cause the power supply to generate a service request
Description:
When a Service Request Enable Register bit is set (“1”), the corresponding Status Byte Register bit
(set to “1”) causes the RQS and MSS bits to be set (1 = set = enable function, 0 = reset = disable func-
tion). All enabled Service Request Enable Register bits are logically ORed to set bit 6 (MSS/RQS) of
the Status byte register. Bit 6 is also set by the power supply to request service (RQS). (See also Fig-
ure 3-12, *STB?)
Example:
*SRE112
Power supply will set bit 6 (MSS/RQS) if any event status register bit is set (ESB = 1),
or any message is available (MAV = 1)

See *SRE command (Figure 3-11) and *STB? command (Figure 3-13).
Example:
*SRE?
Power supply responds with 32 to indicate that the power supply will request service
