A trigger event is initiated based on the type of violation that occurs and the sequence of violations
that occur.
Violation Description
T Only one state is required to initiate a trigger event. The signal has at least one data point
inside (above) the mask. The trigger event occurs when the instrument detects the
fi rst
signal with a point violating the mask. A trigger event could occur on the fi rst acquisition.
F Only one state change is required to initiate a trigger event. The signal has all data points
outside (below) the mask. The trigger event occurs when the instrument has detected
the
fi rst spectral waveform that lies completely below (outside) the mask. A trigger event
could occur on the fi rst acquisition.
T - F (Out)
Two states are required to initiate a trigger event. The signal must be inside the mask
and then passes out of the mask. The trigger event occurs when the
fi rst non-violating
waveform is detected.
F - T (In) Two states are required to initiate a trigger event. The signal must be outside the mask
and then passes into the mask. The trigger event occurs when the
fi rst non-violating
waveform is detected.
T - F - T (Out & In) Three states are required to initiate a trigger event. The signal starts inside the mask and
then passes out of the mask. Next, the signal must pass into the mask. The trigger event
occurs at the second transition where the signal passes back into the mask.
F - T - F (In & Out) Three states are required to initiate a trigger event. The signal starts outside the mask and
then passes into the mask. Next, the signal must pass back outside the mask. The trigger
event occurs at the second transition where the signal passes back out of the mask.
