Color Bars
For fun, here's the output response from a Color Bar pattern. (provided by Comcast in NTSC on Cable 119. Go Figure).
The bottom trace is the detector output, and the top is the CRT Grid.
I'm not sure exactly how much horizontal bandwidth I should expect, but there is exactly ZERO color subcarrier left on that signal by the time it hits the CRT. Those are pretty soft luminance steps, too. And, I don't think thats really color at the detector either. Maybe IF out of alignment?
