Noisy Signals If the signal you are probing is noisy, you can set up the oscilloscope to reduce the
noise in the trigger path and on the displayed waveform. First, stabilize the
displayed waveform by removing the noise from the trigger path. Second, reduce
the noise on the displayed waveform.
1 Connect a signal to the oscilloscope and obtain a stable display.
