3. Push Dots Only On Off on the side menu.
Dots on will display the waveform record
points as dots on the screen. Dots off
connects the dots with vectors.

8. To display the amplitude from one waveform
against the amplitude from another, push
XY
Display . Then push Triggered XY from the
side menu.
A data point from the
fi rst waveform
speci fi es the horizontal location while the
corresponding data point from the second
waveform speci
fi es the vertical location for
each displayed point.
You can optionally view both the YT and XY
displays simultaneously on the same screen.
Quick Tips
Variable persistence accumulates record points for a speci fi ed time interval. Each record point decays independently
according to the time interval. Use variable persistence for displaying infrequently appearing signal anomalies, such
as glitches.
In fi nite persistence continuously accumulates record points until you change one of the acquisition display settings. Use
in fi nite persistence for displaying unique signal anomalies, such as glitches.
The XY Display mode graphs the data in fi xed pairs of waveforms against one another.
