Example 5: Application of X-Y Function
Examine the Phase Difference between Signals of two Channels
Example: Test the phase change of the signal after it passes through a circuit network.
X-Y mode is a very useful when examining the Phase shift of two related signals.
This example takes you step by step to check out the phase change of the signal after
it passes a specified circuit. Input signal to the circuit and output signal from circuit
are used as source signals.
For the examination of the input and output of the circuit in the form of X-Y
coordinate graph, please operate according to the following steps:
(1)
Set the probe menu attenuation coefficient for
10X
and that of the switch in the
probe for
10X
(see "
How to Set the Probe Attenuation Coefficient
(2)
Connect the probe of channel 1 to the input of the network and that of Channel 2
to the output of the network.
(3)
Push the CH1 to CH4 button to turn on CH1 and CH2, turn off CH3 and CH4.
(4)
Push the
Autoset
button, with the oscilloscope turning on the signals of the two
channels and displaying them in the screen.
(5)
Push
CH1
button to select CH1, turn the
Vertical
Scale
knob, and then push
CH2
button to select CH2, turn the
Vertical
Scale
knob, making the amplitudes
of two signals equal in the rough.
(6)
Push the
Display
button and recall the Display menu.
(7)
Select
XY Mode
in the bottom menu. Select
Enable
as
ON
in the right menu.
The oscilloscope will display the input and terminal characteristics of the network
