Abstract 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 1dB 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 highprecision network analyzers, and the effect of error correction is verified, which can be used for measurement of RF transmission network parameters in the laboratory.
