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:
Press the Acquire button to display the Acquire menu.
Press the H1 button to display ACQU Mode menu.
Press the F2 button to choose Peak detect.
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 83).
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.
