LEADER LT1606 User Manual
The LT 1606 extends the flexibility of programmable
RGB generators,in terms of stock and custom patterns
and raster parameters (within limits),into the testing of
monitors and systems that operate in fully encoded
NTSC,PAL and the new HDTV analog-component systems. NTSC and PAL outputs contain fully encoded sub-
carrier and burst and are available in full composite and
separate Y/C using the standard 4-pin SVHS connector.
Analog-component feeds YPbPr, as well as actively
buffered RGB,are available at the same time,making the
encoder an extremely useful tool for engineer ing, setup
of HDTV projectors,service and QC applications.
