扫频信号发生器的问世为扫频测试技术的发展提供了条件。在经过相当一段时间的发展后,扫频测试技术已成为测试领域中的一个新分支,并越来越多地得到工程技术人员的重视。导至扫频测试技术发展的是由于工程技术发展的需要。随着微波技术的发展,人们要在一个很宽的频率范围内了解器件或装置的完整特性并进行最佳设计,这就客观地促进着新的测试方法的发展。扫频测试技术较之传统的点频测试有不 The advent of swept-frequency signal generator for the development of frequency sweep test technology provides the conditions. After a long period of development, sweep test technology has become a new branch in the field of testing, and more and more attention by engineers and technicians. Lead to the development of frequency sweep test technology is due to the development of engineering and technical needs. With the development of microwave technology, it is objectively to promote the development of new test methods to understand the complete characteristics and optimize the design of devices or devices over a wide range of frequencies. Sweep test technology compared to the traditional point frequency test is not
