摘要： 脉冲调制信号是雷达和数字通信系统中的一类重要信号。本文主要研究脉冲调制信号的功率测量方法，讨论并分析了脉冲调制信号的频谱特点，提出使用频谱分析仪实现脉冲调制信号的平均功率和峰值功率的测量，并采用正弦调幅法对频谱分析仪的测量结果进行验证。实验表明使用频谱仪测量脉冲调制信号功率简单易行且具有较高的测量精度。

Abstract: Pulse modulation signal is an important signal in radar and digital communication system. The power measurement of pulse modulation signal is studied in this paper. This paper discussed and analyzed the spectrum characteristic of pulse modulation signal and proposed to measure the mean power and the peak power of pulse modulation signal with the spectrum analyzer. The sine amplitude modulation method is used to verify the power measurement result of the spectrum analyzer. The result of experiment demonstrates that power measurement on pulse modulation signal with spectrum analyzer is simple and feasible and has more precision to measure the power.

Key words:  Pulse modulation, Mean power, Peak power, Sine amplitude modulation
