Threshold Level and Sensitivity
The threshold level is the trigger (input) level at which the counter begins the
signal count (i.e. measurement). This level is the center of the hysteresis band -
the band which represents counter sensitivity. For a count to occur, the signal
must cross the upper and lower limits of the band in opposite directions
(polarities). Figure 4-4 identifies these characteristics and conditions of the input
signal. The dynamic range of the input signal is indicated on the front panel.
