Infinite persistence

6000 Series Oscilloscope User's Guide
• Press the Display key to view the Display menu.
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 normal
color with normal intensity. Waveform persistence is not kept
beyond the display area boundary.
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, then press
persistence. The display will begin accumulating multiple
acquisitions. The accumulated waveforms are shown in gray
with reduced intensity.
3 Press the Clear Display softkey to erase previous acquisitions.
The oscilloscope will again start to accumulate acquisitions.
4 Turn off infinite persistence, then press the Clear Display key
to return the oscilloscope to the normal display mode.
Accumulating multiple acquisitions
Turning off infinite persistence does not clear the display. This allows you to
accumulate multiple acquisitions, stop acquisitions, and then compare future
acquisitions to the stored waveforms.
