利用彩色电视副载波信号校频是一项新技术,它与传统的校频技术相比,具有花钱少,方法简便,测量快速,精度高等优点。目前国内生产使用的彩色副载波校频仪,从基本原理分有锁相式和监相式两种。然而,它们的测量和误差数据处理都靠人工进行,不但繁锁,而且效率低,可靠性差。我们应用 TP801单板机与上述两类彩色副载波校频仪组成自动测试和误差数 The use of color television subcarrier signal frequency correction is a new technology, compared with the traditional school-frequency technology, with less money, the method is simple, fast measurement, high accuracy and so on. At present, the domestic production of color subcarrier frequency analyzer, from the basic principle of phase-locked and phase-monitoring type two. However, their measurement and error data processing are performed manually, not only cumbersome, but also inefficient and poor reliability. We use TP801 single board machine with the above two types of color subcarrier frequency meter automatic test and the number of errors
