Separating the Signal from Noise
Now you want to analyze the signal shape and ignore the noise. To
reduce random noise in the oscilloscope display, follow these steps:
1. Push the ACQUIRE button to see the Acquire Menu.
2. Push the Average option button.
3. Push the Averages option button to see the effects of varying the
number of running averages on the waveform display.
Averaging reduces random noise and makes it easier to see detail in a
signal. In the example below, a ring shows on the rising and falling
edges of the signal when the noise is removed.
