Figure 3-1 The Vpp and Freq measurement Window
Example 2: 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 the input and output.
Do these steps as followings:
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. Click the key AUTO on the panel.
4. Adjust the vertical scale and offset to display approximately the same amplitude
signals on each channel.
5. Select Time Base->X-Y format in Horizontal menu. The Scope Meter will display a
Lissajous pattern representing the input and the output characteristics of the circuit.
6. Adjust the scale and offset of the horizontal and vertical to a desirable waveform
display. The following picture shows a typical example.
7. Apply the Ellipse Method to observe the phase difference between the two channels.
