Waveform display settings
This section contains concepts and procedures for displaying and removing a waveform.
Displaying and removing a waveform
Use this procedure to turn on or off the display of each channel’s waveform.
1.
To add or remove a waveform from
the display, push the corresponding
front-panel channel
Menu
button.
If the selected channel is already active, pushing the channel
Menu
button removes the waveform.
If the channel is not active, pushing the channel
Menu
button selects that channel; another push removes the waveform
from the screen.
If more than one waveform is on the screen, selecting a channel draws the corresponding waveform on top of all other
waveforms.
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 in
fi
nite persistence times 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
fi
rst.
In
fi
nite 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.
