upward path and 1NITiate:CONTinuous is OFF, it exits upward to the idle state.

Inside Event Detection States. Figure 1-38 illustrates the operation of an arbitrary event detection state named <state-name>. Typical <state-names >are TRIGger, ARM, STARt , and STOP.

Normal downward execution is controlled by the source command.

SOURce

The : <state-name> : SOURce command specifies which particular input can generate the event required to continue the downward path. If the source chosen is a non-analog signal, such as IMMediate, BUS, or TIMer , no further qualifications are required to generate an event. If, however, an INTernal or EXTernal analog signal is chosen, additional qualifications may apply. You specify these additional qualifications using appropriate LEVel, SLOPe, and HYSTeresis commands. Sending *RST sets the SOURce to IMMediate.

The downward path also provides a command to override normal operation.

IMMediate

The : <state-name> : IMMediate command bypasses event detection, ECOunt, and DELay qualifications one time. The upward path through the event detection state contains only one condition. A

:<state-name> : COUNt command sets the number of times the trigger system must successfully exit that event detection state on a downward path. If this condition is satisfied, the trigger system exits upward.
