The signal is 1.0 V p-p (with H-sync) from 75 without termination.The iris video signal is composed to average the video level in the center area of each frame and canbe output as a composite signal with H-sync. As shown in the following figure, each frame has itsown video level which is averaged.Fig. 7. Iris videoDAC1μ1K2K20.1μ+5VIRIS Video Out
