摘要
为了在遥测系统中产生多种调制模式的中频信号,进行了ICS-564A DAC卡应用程序开发,使其工作于连续正交转换模式,计算I,Q基带数据以及设置调制参数等,正确地产生了需要的信号,从而证明该系统具有可编程能力强、操作灵活的优点,能够满足使用需求。
It is required to generate multi-mode modulated signals for a telemetry system. An application program for ICS-564A DAC is developed,which works at continuous and quadrature modulation mode to calculate baseband I,Q data, and setup modulation parameters. Thereby, the required telemetry signals are correctly generated. It is proved that the system has merits of better programmability and flexibility to be operated, and can meet application requirements.
