Click click
A kind of harassment that exceeds the quasi-peak limit of continuous disturbance, lasts no more than.200ms, and the latter harassment is from the previous disturbance At least.200ms. The duration is determined by a signal that exceeds the intermediate frequency reference level of the measurement receiver. A click may contain many pulses; in this case, the correlation time is from the first pulse to the end of the last pulse time.
Note. Certain types of harassment are not included in this definition under certain conditions (see 4.2.3). 3.3
