XT—1型电视图象信号发生器的试制和试生产的基础上,根据用户的反映我们在兄弟单位的协助下进行了多方面的电路改进。在本年度试制成功XT—1A型视频图象信号发生器,并通过了设计定型。 XT—1A型视频图象信号发生器设计方案的主要倾向是为黑白电视广播接收机的指标测试和检验服务,同时也为它们的指标调整工作服务。本仪器基本上参照“第四机械工业部黑白电视广播接收机的测量方法”中所律定的图象信号设计。
XT-1 TV image signal generator trial and trial production based on the user’s response based on our brothers unit with the help of a wide range of circuit improvements. In this year’s successful trial XT-1A video image signal generator, and adopted the design stereotypes. XT-1A video image signal generator design program is the main tendencies for the black and white TV broadcast receiver index testing and inspection services, but also for their indicators to adjust work services. The instrument is basically in reference to the “fourth Ministry of Machinery Industry black and white TV broadcast receiver measuring method” in the law decided by the image signal design.
