摘要
介绍了基于S3C2410X的嵌入式测试系统的结构、用途和特点,以及对ZPW 2000A进行测试的原理和算法。使用数字信号处理的方法,通过对信号频谱做细化处理,可大幅度提高频率测试精度。实际测试表明,该方法能对移频信号进行准确的频率测量。
The structure, uses, and characters of the testing embedded system based on S3C2410X processor were introduced. The principle and algorithm for testing ZPW-2000A were also introduced. ZFFT was implemented by DSP method, which greatly improved the accuracy of the frequency test. Actual test shows that the method can precisely measure the frequency of frequency-shift signal.
