DA-16B型晶体管毫伏表是绍兴三五仪表厂在DA-16型晶体管毫伏表基础上,进行改型设计并试制成功的。该仪表采用放大——检波式,故具有较高的灵敏度和稳定度。检波后再进行负反馈,使在小信号检波时,具有良好的线性,可广泛用于工厂、实验室进行正弦波电压有效值的测量。仪表频带宽,从20赫至2兆赫;采用两级分压,测量电压范围广,从100微伏至300伏。该仪表为携带式电子仪器,采用全晶体化,机内结构简单,设计合理,体积小,重量轻。主要部件有射极输出器、放大器、检
DA-16B-type transistor millivoltmeter is Shaoxing Miyaguchi Miriam on the DA-16 transistor millivoltmeter based on the modified design and trial success. The instrument uses amplification - detection type, it has high sensitivity and stability. Negative feedback after the detection, the detection of small signals, with good linearity, can be widely used in factories, laboratories, sine wave voltage RMS measurement. The instrument frequency bandwidth, from 20 Hz to 2 MHz; using two partial pressure, measuring voltage range, from 100 micro-volts to 300 volts. The instrument for portable electronic equipment, all-crystal, the machine structure is simple, reasonable design, small size, light weight. The main components are emitter output, amplifier, seized
