Separate Noises from the Signal
When focusing on signal itself, the important thing is to reduce the noise level as lower as
possible, this would enable user to have more details about the signal. The Average function
offered by our Oscilloscope can help you to achieve this.
Here are the steps for how to enable Average function.
(1) Push the Acquire button to display the right menu.
(2) In the right menu, select Acqu Mode as Average.
(3) Turn the M knob and 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 0-5).

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 P13).
(2) Connect the probe of channel 1 to the input of the network and that of Channel 2 to the
