(2) Select Acqu Mode in the bottom menu.
(3) Select Average in the right menu, select the average number in the left
menu, observe the waveform obtained from averaging the waveforms of
different average number.
User would see a much-reduced random noise level and make it easy to see
more details of the signal itself. After applying Average, user can easily identify
the burrs on the rising and falling edges of some part of the signal (see
Figure
8-5 ).

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.
