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.
Specifically, this event bit indicates that the pending operation condition has
transitioned from TRUE to FALSE.
If
the :TRIGger:COUNt:AUTO is OFF, or
statistics are disabled, or
the function is set to Voltage Peaks,
then the pending operation condition is set TRUE when either: 1) a single
measurement is initiated, or 2) a continuous measurement cycle is initiated.
The pending operation condition is set FALSE when the measurement cycle
terminates.
