HP WaterSkis E1412A, WaterSkis E1312A manual SRE and *SRE?, RST does not affect

*OPC?

*OPC? causes the HP E1312A and HP E1412A to wait for all pending operations to complete. A single ASCII “1” is then placed in the output queue.

Executable when Initiated: Yes

Coupled Command: No

*RST Condition: none

*SRE and *SRE?

*SRE <unmask> specifies which bits of the Status Byte Register are enabled (unmasked) to generate a IEEE-488.1 service request. Event and summary bits are always set and cleared in the Status Byte Register regardless of the unmask value. <unmask> is the sum of the decimal weights of the bits to be enabled allowing these bits to pass through to the summary bit RQS (bit 6 in the status byte).

*SRE? returns the current enable unmask value.

Parameters

Parameter Name	Parameter Type	Range of Values	Default Units
<unmask>	numeric	0 through 255	none

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

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