一种可替代进口的、用于小信号宽频段扫频测试的驻波比电桥,在总参第六十三研究所研制成功。从而打破了国内高频调谐器生产线使用此种电桥需依赖进口的局面。该电桥与双踪显示器及相应的扫频信号源配合使用,可同时显示出小信号输入时被测网络的幅频特性和反射特性,测试方便。对于10～1000MHz 全频段的天线放大器、宽带放大
An alternative to imports, for the small-signal wideband swept-frequency test SWB bridge, the General Staff in the sixty-third Institute successfully developed. Thus breaking the domestic high-frequency tuner production line using such a bridge need to rely on the import situation. The bridge with the dual-track display and the corresponding sweep source with the use of the same time can be displayed at a small signal input amplitude and frequency characteristics of the network under test reflection characteristics, easy to test. For 10 ~ 1000MHz all-band antenna amplifier, broadband amplification
