幅相特性对矢量信号分析性能影响

The Affection Brought up by Magnitude and Phase in Vector Signal Analysis

文中介绍矢量信号分析仪射频到中频的接收通路,分析测量通路通带内的幅度波动特性、群时延波动特性和放大器非线性失真,以及这些因素对数字解调分析的性能影响,并且讨论补偿修正的重要性和方法。

In this peper, the receiver circuit of the vector signal analyzer is introduced simply, magnitude distortion and gtou- delay distortion and nonlinearity of the amplifier of the receiver are analyzed, the affection based on digital bemodulation brought up by these factor is also analynd, and it is discussed the importance of compensating and the method of compensating.
