摘　　要：针对CISPR 16-1-1第三版允许基于FFT的测量仪器用于EMI认证测量的要求,提出了产品标准对FFT接收机的采用情况,并根据基于FFT的EMI测试接收机原理,对其使用方法和限制进行了说明。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.
