Chapter 3 Programming Your Counter for Remote Operation
Status Reporting

A detailed description of each bit in the Standard Event Status Register
follows:
•
Bit 0 (Operation Complete) is an event bit which is generated in
response to the *OPC command. This bit indicates that the Counter
has completed all pending operations (the pending operation condition
has transitioned from TRUE to FALSE).
If AVERage:STATe is OFF, the command INIT;*OPC sets the OPC bit
once the instrument completes a measurement; if AVERage:STATe is
ON, the command INIT;*OPC sets the OPC bit once the instrument
completes a measurement consisting of AVERage:COUNt
measurements.
NOTE
The OPC bit is not in any way affected by the *OPC? query.
•
Bit 1 is not used.
•
Bit 2 (Query Error) is an event bit which indicates that either 1) an
attempt was made to read the Output Queue when it was empty or 2)
data in the Output Queue has been lost.
