摘要
介绍GPS信号仿真器的性能,并针对其特点对主要参数(频率、小信号电平,QPSK)给出了相应的校准方法。详细阐述利用高性能频谱仪进行小信号测试的手段,并提出在实验室环境下进行校准所需注意的几个方面。
This paper introduces the performance of GPS Signal Simulator and the method of calibration of its main parameters（Frequency、Small-Signal Level , QPSK）. The paper expound the way how to use a high performance spectrum analyzer to test the Small-Signal. In addition, it mentions some details we need to pay attention during the measurement in a laboratory test environment.
