will display the waveform record points as
dots on the scr
een. Dots off connects the
dots with vectors.

7. To display the amplitude from one waveform
against the amplitude from another, push
XY Displ
ay. Then push Triggered XY on
the side menu.
A data po
int from the first waveform
specifies the horizontal location while the
corresponding data point from the second
wavefo
rm specifies the vertical location for
each displayed point.
Quick Tips
Variable persistence accumulates record points for a specified time interval. Each record point decays independently
according to the time interval. Use variable persistence for displaying infrequently appearing signal anomalies, such
as glitches.
Infinite persistence continuously accumulates record points until you change one of the acquisition display settings. Use
infinite persistence for displaying unique signal anomalies, such as glitches.
The XY Display mode graphs the data in fixed pairs of waveforms against one another. You can use CH1 versus CH2,
and REF1 versus REF2. On four-channel models, you can also use CH3 versus CH4, and REF3 versus REF4.
When the X Y Display is on, an upper window appears that displays data versus time.
