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) Press the Acquire button to display the Acquire menu.
(2) Press the H1 button to display ACQU Mode menu.
(3) 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 7-4).
Figure 7-4 Signal with Noises
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) Press the Acquire button to display the Acquire menu.
