实验室及加工厂试验和调整无线电设备时,常需用到测量放大器,它可以放大和测量弱信号.在配合测量系统时,又可测量行波系数.我们试制了一台晶体管化的测量放大器,现介绍于下.主要技术特性(一)放大器的工作方法有两种:作宽频带放大时可放大100～10000赫频率范围内的低频弱信号;在
Laboratory and processing plant testing and adjusting radio equipment, often need to use the measuring amplifier, which can amplify and measure weak signals in conjunction with the measuring system, but also measure the traveling wave coefficient.We have trial-produced a transistorized measuring amplifier , Are introduced below. Main technical characteristics (A) There are two working methods of the amplifier: for wide band amplification can amplify the low frequency weak signal within the range of 100 ~ 10000 Hz; in
