Multimeter Command Reference 165Chapter 3

*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.

Comments • Executable when Initiated: Yes

• Coupled Command: No

• Related Commands: *OPC, *WAI

• *RST Condition: none

*RST

*RST resets the HP E1312A and HP E1412A as follows:

-- Sets all commands to their

*RST state.

-- Aborts all pending operations.

*RST does not affect:

-- The output queue

-- The Service Request and Standard Event Status Enable Registers

-- The enable unmasks for the Questionable Signal Registers

-- Calibration data

Comments • 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

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

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