摘要：
The limits and the measurement methods for the radiated emissions above 1 GHz have been published as CISPR22 Ed. 5 Amendment 1 and CISPR16-2-3 Ed. 1 Amendment 1, respectively [1], [2]. VCCI Technical Sub-committee has examined the measurement methods for the radiated emissions above 1 GHz [3]. This paper describes the matter of the signal to noise ratio (S/N) for the radiated emission measurement system above 1 GHz, the setting for the video band width (VBW) of a spectrum analyzer and the influence that the rotational speed of a turntable and the sweep time of a spectrum analyzer exert on radiated emission measurement above 1 GHz, based on the measurement results.
