上海无线电二十一厂在有关单位协助下,最近试制成功SR-46型高灵敏度二线示波器,经过有关部门测试鉴定,认为技术性能完全符合设计要求。它为我国电子测量技术领域填补了一项空白。 SR-46型示波器系晶体管化、积木式结构,采用插件形式,装拆维修方便。它的电路主要由双通道Y轴高增益放大器、触发整形器、时基发生器、校准信号、低频放大器、显示电路以及高、低压电源等单元组成。它能同时观察和测定两种不同的低频微弱信号的瞬变过程,可供操作人员进行对比、分析和研究之
Shanghai Radio 21 Factory in the assistance of the relevant units, the recent successful trial SR-46-type high-sensitivity second-line oscilloscopes, after testing the relevant departments identified that the technical performance in full compliance with design requirements. It has filled a blank for the field of electronic measurement technology in our country. SR-46-based oscilloscope transistor, building block structure, the use of plug-in form, assembly and disassembly easy maintenance. Its circuit mainly consists of dual-channel Y-axis high-gain amplifier, trigger shaper, time base generator, calibration signal, low-frequency amplifier, display circuit and high and low voltage power supply unit. It can simultaneously observe and measure the transient process of two different low-frequency weak signals for operator comparison, analysis and research
