摘　　要：传统的发射机参数测量方法是在发射机非播出时段,测试人员按照测试标准对参数进行测量,并记录测试结果。针对这种传统发射机参数测量方法的效率低、数据存储不便和对测试人员要求较高等缺点,提出了一种实时在线测量发射机参数的动态测量方法。该动态测量方法是在发射机正常工作时段,通过对实时采集到的发射机输入输出数据进行运算处理,得出发射机参数值,具有更好的实时性和准确性。本文论述了实时在线动态测量方法的系统模型,并对新方法可能产生的误差进行了分析。the traditional methods for measuring the parameters of the transmitter is in the case of transmitter non-work time,the tester manually measure the parameters according to the test standard and manually record the test results.In view of the shortcomings of traditional methods,this paper presents an automatic online method of measuring transmitter parameters in real time.In this paper,we would give a model of the online measurement system.the measurement method based on real-time acquisition to the transmitter of input and output data for processing,it has better real-time and accuracy.This paper discusses the model of real-time on-line measurement method and analyzes the possible errors of the new method.
