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.
2 Remove the noise from the trigger path by turning on high-frequency rejection,
low-frequency rejection, or noise reject.
3 Use "Selecting the Acquisition Mode" on page 54 to reduce noise on the
displayed waveform.

The edge trigger level for the Line source is not adjustable. This trigger is synchronized with the
power line supplied to the oscilloscope.

NOTE: Many video signals are produced from 75
Ω sources. To provide correct matching to these
sources, a 75
Ω terminator (such as a Keysight 11094B) should be connected to the oscilloscope
input.
