Noise Rejection
Noise rejection minimizes the possibility of triggering on a noise signal reducing the
trigger sensitivity. This decrease in sensitivity does require a greater amplitude
waveform to trigger the oscilloscope.
Press MENU Setting Noise Reject in the trigger control area (TRIGGER) at
the front panel to enable or disable noise rejection.
