说明： 本系统是基于零中频正交解调原理的简易频率特性测试仪，用于检测被测网络的幅频特性和相频特性。该系统主要包括DDS集成模块，RLC串联谐振电路，乘法器电路，低通滤波器，同相放大器和测量显示模块，其中RLC串联谐振电路作为被测网络。本系统以DDS
集成模块为核心，将其产生的正交扫频信号通过被测网络后，经乘法器得到高频信号；这两个信号经过低通滤波、同相放大后得到符合要求的I、Q直流分量；最后通过单片机进行ADC
采样、数据处理和液晶显示，得到被测网络的幅频特性和相频特性。本系统在算法上的创新之处是，在测量之初，采用短接被测网络即内测校准的方法减小了系统误差。经最终测试，本系统能很好地完成被测网络的频率特性测试。
(This system is based on the principle of zero-IF quadrature demodulator simple frequency characteristic tester for detecting measured amplitude-frequency characteristics and phase-frequency characteristics of the network. The system includes an integrated module DDS, RLC series resonant circuit, multiplier circuit, a low-pass filter, inverting amplifier and measurement display module, which RLC series resonant circuit as a test network. This system DDS
Integrated module as the core, which produces orthogonal sweep through the network under test, by the multiplier to obtain a high-frequency signal the two low-pass filtered signal, amplifying get back in line with the requirements of the I, Q DC component Finally, the single-chip ADC
