Figure 9 Amplitude Modulation Shown at 40% Intensity

To set or clear infinite persistence

With infinite persistence, the oscilloscope updates the display with new
acquisitions, but does not erase the results of previous acquisitions. All
previous acquisitions are displayed in gray with reduced intensity. New
acquisitions are shown in their normal color with normal intensity.
Waveform persistence is kept only for the current display area; you cannot
pan and zoom the infinite persistence display.
Use infinite persistence to measure noise and jitter, to see the worst- case
extremes of varying waveforms, to look for timing violations, or to capture
events that occur infrequently.
To use infinite persistence to display multiple repetitive events:
1 Connect a signal to the oscilloscope.
2 Press the [Display] key.
