Example 5: Reduce the noise on a signal
See the signal with random noise in figure 3-6.
To reduce random noise, do the following steps:
1. Set the Probe and the channel attenuations to “x10”.
2. Connect the signal to the Scope Meter to display a stable wave.
3. Reduce the noise Select the Acquire Mode in Acquire menu.
If there is noise within the signal and the waveform looks too wide, in this case, choose
average acquisition. In this mode the waveform will be thin and easy to observe and
measure.
Use the Average following the steps:
1. Select Acquire in the Utility menu to enter the Acquire menu.
2. Select Mode to Average, then Press F2 to change the Averages form 2 to 128 to
switch the number of averages that best eliminates the noise from the
displayed waveform.
3. Select Mode to Normal to cancel this function.
