Basic Operation

X-Y Horizontal Mode

X-Y mode changes the display from a volts-versus-time

display to a volts-versus-volts display. The time base is

turned off. CH1 amplitude is plotted on the X axis and CH2

amplitude is plotted on the Y axis.

You can use X-Y mode to compare frequency and phase

relationships between two signals. X-Y mode can also be

used with transducers to display strain versus displacement,

flow versus pressure, voltage versus current, or voltage

versus frequency.

In order to get a better view of the waveform, proper vertical

scale should be selected before selecting the X-Y mode.

Use X-Y mode to compare two signals with the same

frequency and different phase. Connect the two signal to CH1

and CH2 respectively. Press horizontal MENU key and then

X-Y softkey to select X-Y mode.
