Agilent Technologies B2200A, B2201A manual Opc

SCPI Command Reference *OPC

*OPC

This command starts to monitor pending operations, and sets/clears the Operation Complete (OPC) bit in the Standard Event Status Register as follows:

• If there is no pending operation, sets the OPC bit to 1.

• If there are any pending operations, sets the OPC bit to 0. The bit will be set to 1

	again when all pending operations are completed.
	So, *OPC command is required to enable the OPC bit. To stop monitoring pending
	operations (disable OPC bit), execute the *CLS command.
	For details about the Standard Event Status Register, see “Standard Event Status
	Register” on page 5-58. Also, see *WAI command.
