The Application of the X-Y Operation
X-Y Plot acts to analyze correlation of data of two channels. Lissajous diagram is
displayed in the screen when you use X-Y Plot, which enables to compare frequencies,
amplitudes and phases of counterpart waveform against the reference waveform. This
makes it possible to compare and analyze frequency, amplitude and phase between
input and output.
Do these steps as follows:
1. Set the probe attenuation to “ x10 ”. Set the switch to “ x10 ” on the probes.
2. Connect the CH1 probe to the input of the circuit, and connect the CH2 probe to the
output of the circuit.
3. Adjust the vertical scale and offset to display approximately the same amplitude sig-
nals on each channel.
4. Select X-Y format at Horizontal window. The oscilloscope will displays a Lissajous pat-
tern representing the input and the output characteristics of the circuit.
5. Adjust the scale and offset of the horizontal and vertical to a desirable waveform dis-
play. The following picture shows a typical example.
6. Apply the Ellipse Method to observe the phase difference between the two channels.
