Example 4: Analyze the Details of a Signal

Noise is very common inside most of the electronic signal. To find out what's
inside the noise and reduce the level of noise is very important function our
oscilloscope is capable to offer.
Noise Analysis
The level of noise sometime indicates a failure of electronic circuit. The Peak
Detect functions acts an important role to help you to find out the details of
these noise. Here is how we do it:
(1) Click to call up the menu panel. Click the Acquire softkey on panel 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) Click to call up the menu panel. Click the Acquire softkey on panel to
display the Acquire menu.
