As shown in Figure 11-1, there are four status register sets in the status structure of the
Model 2700: Standard Event Status, Operation Event Status, Measurement Event Status,
and Questionable Event Status.
Register bit descriptions
Standard event register
The used bits of the Standard Event Register (Figure 11-4) are described as follows:
• Bit B0, Operation Complete (OPC) — Set bit indicates that all pending selected
device operations are completed and the Model 2700 is ready to accept new com
-
mands. This bit only sets in response to the *OPC? query command. See
Section 12 for details on *OPC and *OPC?.
