Thanks Trevor
Well thats a quick and dirty way but not as I remember it. Pic quality was good.
It was a Test Gear Dept. so unlikely that we would have had a Spectrum Analyser. Seems to me some sort of voltage step generator was needed to produce different levels into a channel input and then the timebase would do the line scan. Would need some sync and then of course the video should be easy.
