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
" on
P11).
(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
Autoset
button, with the oscilloscope turning on the signals of
the two channels and displaying them in the screen.
(4)
Turn the
Vertical
Scale
knob, making the amplitudes of two signals equal
in the rough.
(5)
Push the
Acquire
button to display the right menu.
(6)
In the right menu, select
XY Mode
as
ON
. The oscilloscope will display the
input and terminal characteristics of the network in the Lissajous graph
form.
