摘　　要：频谱分析仪是常用的射频测量仪器之一。在测试和分析各种信号时,必须选择合适的检波方式才能正确反映它们的特性,如果选择不合适的检波方式可能会导致测试结果出现误差或者错误。介绍频谱分析仪的多种检波方式,详细分析采样检波、最大峰值检波、最小峰值检波、自动峰值检波、普通检波、平均值检波、均方根检波、准峰值检波的特点和用途,最后总结了各种检波方式的区别。Spectrum analyzer is one of the radio frequency measuring instruments in common use. Appropriate detector types should be chosen to analyze and measure a variety of signals to show their characteristics correctly,the results would be inaccurate or absolutely wrong when inappropriate detector types are chosen. Various kinds of detector types of spectrum analyzer are introduced, the features and applications of sample detector,max peak detector, min peak detector, auto peak detector, normal .detector, average detector, RMS detector and quasi -peak detector are analyzed in detail, the differences among them are concluded.
