To use the XY display mode
The XY display mode converts the oscilloscope from a volts versus time
display to a volts versus volts display. You can use various transducers
so the display could show strain versus displacement, flow versus
pressure, volts versus current, or voltage versus frequency. This
exercise shows a common use of the XY display mode by measuring the
phase shift between two signals of the same frequency with the
Lissajous method.
1 Connect a signal to channel!, and a signal of the same
frequency but out of phase to channel2.
