DYC-5型超高频电子管电压表是上海亚美电器厂的新产品,共作用原理和本刊试刊第一期所介绍的两种通用电子管伏特计中的 GB-1型电子管伏特计相同,电路也相仿,仅将频率范围扩展,其主要技术特性如下:1.在交流电压50赫时量程的满度值:1,3,10,30,100伏±2.5%;2.探极的频率响应:20赫～100兆赫±3%;>100兆赫～200兆赫±5%;>200兆赫～300兆赫+10%;

DYC-5-type UHF tube voltmeter is a new product of Shanghai Yamei Electric Appliance Factory. The principle of action is the same as that of the GB-1 type tube voltmeter in the two general-purpose tube voltmeters introduced in the first issue of this publication. The circuit Also similar, only the frequency range of expansion, the main technical characteristics are as follows: 1 at 50 Hz AC voltage range full scale value: 1,3,10,30,100 volts ± 2.5%; 2 probe the frequency response: 20 Hertz ~ 100 MHz ± 3%;> 100 MHz ~ 200 MHz ± 5%;> 200 MHz ~ 300 MHz + 10%;
