Turning power on, or sending *RST or :ABORT forces the trigger system to the idle state. The trigger system remains in the idle state until it is initiated by 1NITiate:IMMediate or INITiate: CONTinuous ON . Once one of these conditions is satisfied, the trigger system exits downward to the initiate state. Note that *RST sets INITiate : CONTinuous OFF.

Whenever the trigger system leaves the idle state, it sets the instrument’s Operation Pending Flag. Returning to idle clears the flag. The Operation Pending Flag is a special bit inside the instrument that can affect how the instrument responds to certain commands. You need to know this fact when using *OPC, *OPC?, *WAI, and other commands.

Inside the Initiate State. Figure l-37 illustrates the operation of the initiate state.

If the trigger system is on a downward path, it travels directly through the initiate state without restrictions. If the trigger system is on an upward path, and 1NITiate:CONTinuous is ON, it exits downward to an event-detection state. If the trigger system is on an
