One Chip Video Test Generator

[kf4rca]

Have you seen the one chip video test generator? (Search simplest pattern generator.) It uses the CD4060 chip and a crystal as a counter oscillator to produce a six level stairstep signal. Easy to construct. You can use a 1,2,4,8, or 16 MHz. crystal depending on which "Q" outputs you use.
It works well with analog TVs and monitors but digital sets don't like it at all. Operates off a single 9V battery.
Useful in setting up greyscale balance on color sets and as a general video signal source.
