Sets the OPC bit in the Standard Event Register when all overlapped commands complete. It is used to wait for pending overlapped commands to finish before proceeding.

Operation complete query that places an ASCII "1" in the output queue when all previous overlapped commands complete.

Returns the instrument to default conditions. It performs the same actions as reset().

Generates a command interface trigger event for the trigger model.

Requests self-test results. This command always places a zero (0) in the output queue and is included for common command compatibility only; the instrument does not actually perform a self-test.

Suspends execution of subsequent commands until all previous overlapped commands are finished. It pauses until overlapped commands are complete and is not needed for sequential commands.

*WAI

Resets the event and NTR status registers to 0, sets all PTR register bits on, and clears the output queue.

*CLS

Returns the Service Request Enable Register value. The response is a decimal value indicating which bits in the register are set.

Programs the Service Request Enable Register. Use it to set or clear the enable bits that control whether summary events generate a service request (SRQ); a value of 0 clears the register.

Programs the Event Status Enable Register with a mask value. The mask can be set from 0 to 255.
