The terms and definitions defined in GB/T 4365-2003 and the following terms and definitions apply to this document The following terms and definitions defined in CISPR 16-2-1 or CISPR 16-2-2 refer to ground equipment under test (EUT) level weighted clicking sound, which is a disturbance with an amplitude exceeding the continuous disturbance quasi peak limit and a duration not exceeding 200 ms, and the latter disturbance is at least 200 ms away from the previous disturbance. The duration is determined by the signal exceeding the intermediate frequency reference level of the measurement receiver. A click sound may contain many pulses; In this case, the relevant time is the time from the beginning of the first pulse to the end of the last pulse. Note: Under certain conditions, certain types of harassment are not included in this definition (see 4.2.3). The quasi peak indication value generated by the intermediate frequency reference level is equal to the corresponding value generated by the unmodulated sine signal at the intermediate frequency output end of the measurement receiver, which is equal to the continuous disturbance limit. Switching operation A single opening or closing of a switch or contact. Note: It does not depend on whether a clicking sound is observed. The minimum observation time T is the minimum time required to provide sufficient stable data for calculating the number of clicks (or switch operations) per unit of time when counting the number of clicks (or related switch operations) (see also 7.4.2.1). The click rate N generally refers to the number of clicks or switch operations within 1 minute, which is used to determine the click limit value (see also 7.4.2.3)
Function of testing report:
