LEI-522 is uses latest FPGA technology to provide the highest performance for color bar, black burst, or to flip between the two generated patterns. The color bar patterns are SMPTE for NTSC and 75% for PAL. There are two pairs of independently selectable outputs. The timing range is infinite for each output pair for both vertical and horizontal. It may be set-up for alternating between black burst and color bar. The purpose is to confirm frame synchronizer freeze for remote satellite set-up.
