Applications
The Scientific-Atlanta 7550 Video Exciter was designed for cable television headend systems, where it converts baseband video and audio signals into a modulated RF channel for distribution over a coaxial cable network. Scientific-Atlanta (now part of Cisco) was one of the dominant suppliers of headend equipment from the 1970s through the 2000s, and the 7550 series was widely deployed in cable franchises across North America during the analog cable era. These exciters were also used in satellite uplink and broadcast distribution environments where a stable, modulated video carrier was required. Today, 7550 units remain in demand for legacy analog cable system maintenance, parts sourcing, and headend restoration projects, as well as for collectors and engineers working with analog broadcast equipment.
This Scientific Atlanta 7550 Video Exciter (Assembly 262160) was pulled from a working cable/broadcast environment where it was in active use and functional. It has been inspected and is in good used condition. The chassis shows normal wear consistent with rack-deployed equipment. One module slot is populated and one slot is empty, as shown. Please review our photos and contact us with any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
