录象机 RF 转换器的输出频率必须和电视接收调谐器的输入频率相同,但当录象机和接收机都采用多频道的电子调谐器时,要使两者在各频道调谐一致是麻烦的事情。采用带测试信号的视频较换集成电路 BA7024(日本 ROHM 公司产)可以有效地解决这一难题。
The output frequency of the video recorder RF converter must be the same as the input frequency of the television receiving tuner. However, when both the video recorder and the receiver use a multi-channel electronic tuner, it is troublesome to make both tuned in each channel uniformly thing. Using test signal with the video signal to replace the integrated circuit BA7024 (Japan ROHM company) can effectively solve this problem.
