Speci fi cations
Option BG speci fi cations
The following tables list the electrical characteristics and the environmental
characteristics of the BG Option.
Table 10: Black and Composite outputs
Characteristic Performance requirements Reference information
Connector BNC
Number of Black outputs 2 BLACK4 and BLACK5
Formats on Black outputs Each output is individually selectable between Bi-level NTSC with or without fi eld ref, NTSC
No setup with or without fi eld pulse, PAL with or without fi eld ref, or Tri-level. The BG option
outputs can only generate tri-leval at one clock rate, so both can be any one of the two
sets: Set 1: 1080i59.94, 720p59.94, 1080p23.98, 1080sf23.98. Set 2: 1080p29.97 1080i60,
1080i50, 720p60, 720p50, 1080p24, 1080p30, 1080sf24, 1080p25
