Trigger Sensitivity: Adjust the trigger level hysteresis window.
Smaller values provide more sensitive triggering, while larger values
increase stability in noisy signals.
Hold-off time: Delay period after each trigger before the trigger cir
cuit resumes operation. It prevents triggering during this interval, even
if the trigger conditions are met. Setting a reasonable hold-off time all
ows stable capture and analysis of burst signal waveforms, commonl
y seen in communication signals with alternating "idle" and "transmiss
ion" patterns.
