摘要
介绍了一种采用频谱分析仪基于贝塞尔函数的调制失真度测量方法。设计了一套遥测发射机调制失真度的测量系统。基于LabVIEW虚拟仪器软件设计上位机控制平台,进行测量控制和数据处理;下位机硬件实现参数测量。此方法简单实用,大大提高了测量效率。
A method of modulation distortion measurement by spectrum analyzer and Bessel function is introduced.A measurement system of telemetry transmitter modulation distortion is designed.PC control platform is designed based on LabVIEW virtual instrument software for measurement control and data processing.The parameter measurement is realized by hardware.This method is simple,practical,and greatly improves the measurement efficiency.
