To use the XY display mode

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.
Connect a signal to channel 1, and a signal of the same frequency but
1
out of phase to channel 2.
