sync or black burst.
AUX IN. 75
W input for video signals. Insertion point follows the internal filters.
AUX OUT. 75
W video signal output just prior to the filters. Can be used with
the AUX IN to design custom filters.
PIX MON. 75
W output to drive a picture monitor, signal is output prior to filters
and has a bright-up pulse added when line select is used.
LINE STROBE. A 75
W output that provides a pulse for the selected line(s)
when line select is used. Can also be configured to output the Field 1 pulse, see
Table 2–3 (J1103).
