Example 6: The application of the X-Y operation

Viewing Phase Changes through a Network

Theme: Connect the oscilloscope to monitor the input and output of the circuit and

capture the phase changes through the circuit.

To view the input and output of the circuit in an X-Y display, do these steps:

1. Set the probe menu attenuation to 10X. Set the switch to 10X on the probes.

2. Connect the channel 1 probe to the input of the network, and connect the

channel 2 probe to the output.

3. If the channels are not displayed, press the CH1 and CH2 buttons.

4. Press the AUTO button

5. Adjust the vertical knob to display approximately the same amplitude

signals on each channel

6. Press the MENU in horizontal control area to display the menu

7. Press the Time Base soft button to select X-Y

The oscilloscope displays a Lissajous pattern representing the input and output

characteristics of the circuit

8. Adjust the vertical

and knobs to display a desirable

waveform.

9. Apply the Ellipse method to observe the phase difference between the two

channels.
