functions acts an important role to help you to find out the details of these noise. Here
is how we do it:
(1) Push the Acquire button to display the Acquire menu.
(2) Select Acqu Mode in the bottom menu.
(3) Select Peak Detect in the right menu.
The signal displayed on the screen containing some noise, by turning on Peak Detect
function and changing time base to slow down the incoming signal, any peaks or burr
would be detected by the function (see Figure 7-4).

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 Acquire menu.
(2) Select Acqu Mode in the bottom menu.
(3) Select Average in the right menu, 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 7-5).
