4. Use the M ultipu rpo se knob to change and set the Persist Tim e value. The range is Auto (which is the same as 0 s), 0 s -
10 s (in one second increments), and infinity.
5. To clear the persistence of the displayed waveform, select and click Clear Persistence. This does not change the
persistence setting, but just clears the displayed waveform persistence data.
Waveform persisten ce tip
To quickly clear the displayed waveform persistence data, push Single, then push Run/S to p to restart active w aveform
acquisition.
The XY display mode
The XY dis
play mode plots the signal amplitude of channel 1 (X) against the amplitude of channel 2 (Y), where channel 1
is the horizontal axis and channel 2 is the vertical axis. XY display mode is useful for showing signal phase or frequency
relationships between periodic signals. The resulting XY plots are called Lissajou patterns.
You can display Ch 1 versus Ch 2. On four-channel models, you can also display Ch 3 versus Ch 4.
1. Select t
he two signal sources that you
want to plot. Push the Vertical Position
knob for each channel to set the ground
referen
ce of both s ignals to 0 V (center
horizontal graticule) so that the XY plot
is centered on the screen.
