function acts an important role to help you to find out the details of this noise. Here is
how we do it:
1.
Apply Square waveform to CH1 as source signal, press
ACQUIRE
button to
active
ACQU MODE
menu.
2.
Press
F2
to select Peak Detect function. 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 Fig.59).

Signal with Noises
Reduce the effect of noises from your 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.
Apply square waveform to CH1 as a source signal. Press
ACQUIRE
button to
bring up
ACQU MODE
menu.
2.
Press
F3
selection
Average
, Press
F4
to select number of data points for average.
Available choices of number are 16, 32, 64, 128. The higher the number, the
better result user will get.
Use would see a much reduced random noise level and make it easy to see more
details of the signal itself. As it is in Fig.60, after applying Average, user can easily
identify the burrs on the rising and falling edges of some part of the signal(see
Fig.60).
