With a 75-percent red baseband signal, the modulated channel 4 signal is reproduced on the screen (above left). With a 100-percent signal, the screen turns mud-orange-green (above right).
The Setup:
A 75-percent red NTSC signal originating from a Digital Video Essentials DVD swamps CT-100 B8000194 when the baseband signal increases from 75 to 100 percent saturation. The same 100 percent red image is correctly displayed on a digital TV operating in NTSC mode.
An oscilloscope in the lower right hand corner of each picture displays the I signal on the top trace and the red G1 (control grid) signal on the lower trace.
These images were taken with daylight illuminating the room.
Setup showing '50's color western, "The Cisco Kid."
