Waveform of the Noise-Removed Signal
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.
Connect the oscilloscope with the circuit and monitor the input and output signals of
the circuit.
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 P14).
(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 down the
Autoset
button, with the oscilloscope turning on the signals of the
two channels and displaying them in the screen.
(4)
Turn the
VOLTS/DIV
knob, making the amplitudes of two signals equal in the
rough.
(5)
Press the
Display
button and recall the Display menu.
(6)
Press the
H3
button and choose
XY Mode
as
ON
.
The oscilloscope will display the input and terminal characteristics of the network
in the Lissajous graph form.
(7)
Turn the
VOLTS/DIV
and
VERTICAL POSITION
knobs, optimizing the
