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 analog video signals. It can also distribute other pulses and
signals 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 which will hold up to 15 modules, a 350FR portable frame which will hold up to 7
modules or a standalone enclosure that will hold 1 module.
