Noise Rejection
Noise Rejection adds additional hysteresis to the trigger circuitry. Noise rejection
reduces the possibility of noise trigger but also reduces the trigger sensitivity;
therefore, a larger signal is required 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.
