To enable or disable trigger noise rejection

Noise Rej adds additional hysteresis to the trigger circuitry. By increasing the
trigger hysteresis band, you reduce the possibility of triggering on noise. However,
this also decreases the trigger sensitivity so that a slightly larger signal is required
to trigger the oscilloscope.
