摘　　要：调制域分析已经成为现代测试技术不可或缺的部分,在显现频率变化信号时优于时域测量和频域测量。可是建立在调制域基础上的自动测试设备在国内却很少见到。基于调制域分析,设计了电子产品频率调制参数测试方法。借助GPIB高速数据传输总线,设计了无须人工干预的自动测试方案,该方案数据传输快速稳定,并且能适应用户多种测试要求,智能性强。实际使用证明,开发出的系统能够持续稳定地工作,大大提高劳动生产率。Modulation domain analysis has become an important part for modem measurement technology. It is better than time domain and frequency domain measurement when indicating frequency variable signal. But automatic testing system based on modulation domain seldom be seen in China. Based on modulation domain analysis, a frequency modulation parameter testing method is proposed. By GPIB high-speed data bus, a solution for automatic testing without man is designed. The solution transfer data rapidly and adapt many testing requirement of users. It is intelligent. The system work stably in practice and improve product efficiency.
