VERTICAL BLANKING INTERVAL TEST SIGNAL KEYER The Teiechrome Model 1008-A Vertical Blanking Interval Keyer is a selfcontained portable unit that makes possible transmission of television test and control signals between frames of a TV picture. Any test signal (multiburst, stairstep, color bar, etc.) may be added to the composite program signals. The keyer will operate anywhere in the TV system and operates from composite video, sync, or H & V drive. The test signals are always present for checking transmission conditions without impairing picture quality. The home viewer is not aware of their presence. These continuous reference signals may be used in connection with various Teiechrome devices for automatic correction of video level, frequency response, envelope delay, differential gain and differential phase. 1003-C VIDEO TRANSMISSION TEST SIGNAL GENERATOR VERTICAL BLANKING INTERVAL TEST SIGNAL KEYER Portable or standard rack mounting. Self-contained power supply. Test signal is thin line between frames. All test signals can be transmitted during vertical blanking portion of program.
