摘要: |
调频参数的测量,诸如调制频偏、非线性失真、频率响应,通常可采用KF调制度测量仪进行测量。当载频高于1300MHz或频偏大于400kHz时,目前还无法用仪器直接测试。本文介绍一种用频谱仪测量S波段遥测发射机的调制频偏及调制非线性的方法。 |

Abstract: |
The measurement of FM Parameters usually can be made by KF modulation meter. Now,no meter can measure directly when carrier frequency is higher than 1300 MHz or frequency deviation more than 400kHz. This paper describes a method that measures FM deviation and nonlinear of S-band telemetry transmitter. |
