三基线晶体管收音机高频扫频仪,是对已装配好且中频也调整好的收音机进行频率范围和统调点调整的仪器。该机提供了0.5～1.7兆赫、3.5～9兆赫和11～20兆赫而分三根基线同时在九英寸显象管屏幕上显示的扫频信号。借助该机可迅速直观地调整好收音机的频率范围和统调点。本机采用时间分割,以三根基线方式将频率为0.5～20兆赫的扫频信号显示在屏幕上,省去了过去拨动波段开关的麻烦。调整时只要将收音机拨到某波段,在显示屏幕上即有相应的时钟脉冲波出现。视波
Three base-line transistor radio frequency sweeping instrument, is already fitted and the IF also adjust the radio frequency range and tune the instrument adjustment. The aircraft provides 0.5 ~ 1.7 megahertz, 3.5 ~ 9 megahertz and 11 ~ 20 megahertz while the three baseline simultaneously on the nine-inch kinescope screen shows the sweep signal. With the aircraft can quickly and intuitively adjust the radio frequency range and tone points. The machine uses time division, with three baseline frequency of 0.5 to 20 MHz sweep signal is displayed on the screen, eliminating the trouble of switching the band switch in the past. As long as the radio adjustment to a certain band, in the display screen that is the corresponding clock pulse appears. Waves
