To reduce the random noise on a signal
If the signal you are applying to the oscilloscope is noisy, you can set up the
oscilloscope to reduce the noise on the displayed waveform. First, you stabilize
the displayed waveform by removing the noise from the trigger path. Second,
you reduce the noise on the displayed waveform.
1 Connect a signal to the oscilloscope and obtain a stable display.
2 Remove the noise from the trigger path by turning on either
high-frequency reject or noise reject.
High-frequency reject (HF reject) adds a low-pass filter with the 3-dB point at
50 kHz. You use HF reject to remove high-frequency noise, such as AM or FM
broadcast stations, from the trigger path.
