2. Push W

aveform 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.

Auto is not same as 0 seconds. Auto is persistence time that gives the most number of waveforms per second, for a given horizontal

scale. The range of persistence is 1s - 10s in the steps of 1s. There is an option to have persistence set to 0 seconds. This is mode

can be enabled when Persistence is set to OFF. When persistence is set to ON, there is an option to select the amount of persistence

in terms of time ranging from 1s -10s. Further, the amount of persistence can be set to Auto, that gives the best performance.

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 persistence tip

To quickly clear the displayed waveform persistence data, push Single, then push Run/Stop to restart active waveform acquisition.

Note: For FFT waveform, the behavior of the persistence will be as follows.

•

Setting the persistence to infinite, will make the display to retain all the waveforms.

• Setting the persistence to ON (Auto 0 s - 10 s), will have the similar behavior as Persistence set to OFF.

The XY display mode

The XY display 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.

Y

ou can display Ch 1 versus Ch 2 on two-channel models.

1. Select the two signal sources that you want to plot. Push the Vertical Position knob for each channel to set the ground reference of

both signals to 0 V (center horizontal graticule) so that the XY plot is centered on the screen.
