7700ADA7 Analog Video Distribution Amplifier
1. OVERVIEW
The 7700ADA7 Analog Distribution Amplifier is a general purpose amplifier for distributing analog video
signals. The 7700ADA7 features one balanced input with seven outputs. The 7700ADA7 amplifier has
been designed to distribute a wide range of anal og vi deo si gnal s. I t c an al so dis tri but e oth er pu lses an d
si gnals that are less than 2Vp-p.
The 7700ADA7 occupies one card slot and can be housed in a 1RU frame which will hold up to 3
modules, a 3RU frame whic h will hold up to 15 modules, a 350FR portable frame which w ill hold up to 7
modu les or a standalone enclosure that will hold 1 module.
Features:
• 75Ω or high impedance input (jumper selectable)
• High c ommon mode range an d c ommon mode rejection ratio (C M M R)
• Gain control
• Jump er sel ectable AC or DC coupling
• Looping f eature w it h external "T " c onnect or and extern al termi nation
• Consistent input impedance if card power is lost
