自动干扰测量仪的数据采集系统

DATA RECORDING SYSTEM OF AUTOMATIC INTERFERENCE TEST RECEIVERS

本文论证了在自动干扰测量仪中,采用符合CISPR*规定的二阶低通滤波器模拟电表作用的重要性。分析了各个数据输出口的优缺点,提出了根据干扰源特性正确组建数据采集系统的方法。

The importance of the second order low-pass filter simulating the analogindication meter in accordance with CISPR is described in this paper. Thefunctions of different output sockets are also analyzed, and the appropriatedata recording system proposed for different types of noise sources.
