Illustration 4 : Reducing random noise of signals

If the signal being measured is stacked with random noise, you can
adjust the setups of your oscilloscope to filter or reduce the noise, so it
will not cause interference to the signal during measurement.
(Waveform is shown below)
Figure 3-4 Reducing random noise of signals
Steps :
1. As in the previous illustration, set the attenuation factor of the
probe and Ch1.
2. Connect the signal to ensure stable display of waveform. See the
previous illustration for operation instruction. See the previous
chapter for guidance on adjusting the horizontal time base and
vertical range.
