Pendulum CNT-91R Manual

Fig. 3-10 Narrow hysteresis gives errone¬ous triggering on noisy signals.
Fig. 3-11 Wide trigger hysteresis gives correct triggering.
To ensure reliable measuring results, the counter has the following functions to reduce or eliminate the effect of noise:
10x input attenuator
Continuously variable trigger level
Continuously variable hysteresis for some functions
Analog low-pass noise suppression filter
Digital low-pass filter (Trigger Hold-Off)
46 / 50
