The *OPC? query allows synchronization
between the instrument and an external
controller by reading the Output Queue or by
waiting for a service request on the Message
Available (MAV) bit in the Status Byte Register.
The *OPC? query causes the instrument to place
an ASCII character, 1, into its Output Queue
when the device completes all pending
operations. A consequence of this action is that
the MAV bit in the Status Byte Register is set to
state 1.
*OPC?
None

operations have been completed.
