摘　　要：随着科学技术的发展,网络分析仪在射频测量系统中的应用越来越广泛。射频传输网络中的反射特性和传输特性参数、放大器1dB压缩点、滤波器通带带宽等关键性能指标的测试都依赖于网络分析仪,但目前市场上的网络分析仪产品价格均较为昂贵。提出了一种基于常规标准可编程仪表(模块单元)构建较高价值网络分析系统的工程实现方法,并对构建系统的测量误差进行分析,设计了可显著提高测量精度的误差校正方法和校正模型。针对典型器件的关键技术指标,将本系统测试结果与标准高精度网络分析仪测试结果相对比,验证了误差校正的效果和性能指标,可用于实验室内的射频传输网络参数测量。With the development of science and technology,network analyzer is more and more widely used in RF measurement systems.The test of key performance such as reflection characteristics and transmission characteristic parameters in the RF transmission network,amplifier 1 dB compression point,and filter passband bandwidth are all dependent on the network analyzer,but the network analyzer products on the market are expensive currently.In this paper,the network analysis system which can be used for engineering measurement is built by the standard programmable instrument(module unit)in the laboratory,and the measurement error generated by the system is analyzed.The error correction method and correction model which can significantly improve the measurement accuracy are designed.For the key technical index of typical devices,the test results of this system are compared with the test results of standard high-precision network analyzers,and the effect of error correction is verified,which can be used for measurement of RF transmission network parameters in the laboratory.
