摘　　要：对于发射装置用BPSK数字基带调制器的时延测量问题,提出利用宽带数字示波器作为高速数采捕获信号波形、软件解调并计算插入时延的测量方法。论述传输系统中时延的定义,集成了一套实验室级的BPSK调制器时延测量装置。The basic idea in this paper is to realize delay measuring for the BPSK modulator in satellites’ navigation system. Discuss the definition of transmit system delay. From the practice, a delay measuring system of the BPSK modulator based on software radio is established. In the measuring system, a digital oscilloscope is working as a high speed data collector to capture the modulated signal. By using software demodulation,insert-delay measurement is done under BPSK modulation.
