高性能频谱分析仪的时域测量技术及其应用

The Technology and Application of Time Domain Measurement of High Performance Spectrum Analyzer

本文分析了高性能频谱分析仪时域测量功能的原理,并给出其时域测量功能在调幅、调频、脉冲调制测试中的应用。与通用示波器相比,这种测量有其独特之处,可更好地表征信号的部分调制域特性。

This paper analyzes the principle of time domain measurement function of high pefformance spectrum analyzer and its use in Amphtude modulation （AM）, Frequency modulation （FM） and pulse modulation test. Compared with usual oscillograph, this measurement function has its own advantages. It expresses some characters of signal well in modulation domain.
