Setting the waveform persistence
Persistence sets the time for how long the oscilloscope retains and displays the
sampled waveform points on the screen. Using longer or infinite persistence time
helps to display infrequent or random signal anomalies such as glitches.
Normal persistence sets the oscilloscope to erase the current waveform data as it
draws the newest acquisition. Changing the persistence time (from 1 second to
10 seconds) sets how long to retain waveform data points in memory and on the
screen until they are erased. The older data points are erased first.
Infinite persistence sets the oscilloscope to retain and display all acquisition
waveform data points without erasing the previous data.
Changing an acquisition setting, such as Horizontal Position or Scale, Autoset,
and Single, resets the persistence period to start over.
1. Push Acquire.
2. Push Waveform Display side-menu button.
3. Use the Multipurpose knob to select and click Persist Time.
4. Use the Multipurpose knob to change and set the Persist Time value. The
range is Auto 0 s - 10 s (in one second increments), and infinity.
