Abstract According to the new definition of the term “measuring receiver” in CISPR
16-1-1 Ed.3.0, the FFT- based measuring instruments could be used in EMI compliance
measurement. The adoption of the FFT-based EMI receiver in product standards was
forecast as well. Based on the principle of the FFT-based EMI receiver, its timing and
dynamic range considerations were discussed.
