Chapter 4 Command Reference
Introduction
Programming Guide 4-133
*OPC?
(Operation Complete Query)
*OPC?
This query produces a response upon the transition of the measurement cycle from
measuring to idle. This allows synchronization between a controller and the
instrument using the MAV bit in the Status Byte Register or a read of the Output
Queue. (Note that this query does not actually reada state, as most queries do.)
Since this query will not respond until the measurement cycle transitions from
measuring to idle, the only way to cancel the query “holdoffis by Device Clear
(page 4-31) or power-on.
See the section titled “Using the *OPC? Command,page 3- 47,
in Chapter 3 for an example using this command.
Single ASCII-encoded byte, 1.
The *OPC? query does not in any way affect the OPC bit in the Standard Event
Status Register.
