Quadra’s composite video inputs use the industry standard 75
Ω
BNC
connector.
Figure C-1. BNC connector (viewed from rear of chassis)
The BNC connector is designed for use with coaxial cables. Coaxial cables are
well suited for the transmission of high frequency signals over moderate
distances. Please note:
• Coaxial cable is commonly available with a characteristic impedance
of either 50 or 75
Ω.
• 75
Ω
cables and connectors are used exclusively for Video signals.
• For best signal quality, it is important to use a high-quality 75
Ω
coaxial cable.
• The use of 50
Ω
cables will cause a signal mismatch, and this may
result in visible artifacts on video images.
Ready-made cables are available commercially, or they can be easily
customized on site for your particular requirements.
