本文介绍了一种全数字化的彩色/黑白图象信号发生器,其中附有视频D/A转换器板。本仪器不仅能够输出字长为8位的视频数据流,而且还能够输出模拟视频信号。因此,它是调整测试采用直接编码方案的数字图象设备和模拟电视设备的理想仪器。
This article describes a fully digital color / monochrome image signal generator with a video D / A converter board attached. This instrument not only can output 8 bit video data stream, but also can output analog video signal. Therefore, it is the ideal instrument for adjusting digital image equipment and analog television equipment that test direct encoding schemes.
