Enable to view glitches that change relatively slowly or glitches with lower
occurrence probability. The persistence time can be set to 50 ms, 100 ms, 200
ms, 500 ms, 1 s, 2 s, 5 s, 10 s or 20 s.
3. Infinite
In this mode, the oscilloscope displays the waveform newly acquired without
clearing the waveforms acquired formerly. The waveforms acquired formerly will
be displayed in relatively low-brightness color and the newly acquired
waveforms will be displayed in normal brightness and color. Infinite persistence
can be used to measure noise and jitter and to capture incidental events.
