《四》监视量测设备(甲)监视器监视器分为影像监视器和波形监视器两部分。前者可以独立使用,以14 RP 4 A 型显像管显示影像,后者用13 37型示波管显示同步和消隐脉冲的波形以及它们与影像信号间的波幅比例。为了使所显示影像尽可能地与实物相近,影像监视器的质量应高于接收机的,其内部视频放大器的通频带宽于.7.5兆赫。
“Four” monitoring measurement equipment (A) Monitor The monitor is divided into video monitor and waveform monitor in two parts. The former can be used stand-alone to display images in a 14 RP 4 A type CRT, which displays the sync and pedestal waveforms and their amplitude ratio to the image signal using a Type 13 37 CRT. In order for the displayed image to be as close as possible to the real thing, the quality of the video monitor should be higher than that of the receiver with an internal video amplifier with a pass band wider than .7.5 MHz.
