Description
Sigma Electronics SS-2100-16 Series 2100 16-Slot Powered Card Frame BNC Backplane
The Sigma Electronics SS-2100-16 is a 16-slot powered card frame from the Series 2100 modular instrumentation system. The chassis provides a powered, bussed enclosure for modular signal-routing and switching cards, with a BNC-populated backplane and an integrated control buss for centralized communication between installed cards. A Control Buss card (part number 2126) is present in the frame, providing DB9 connectivity for external control.

Applications
The Sigma Electronics Series 2100 is a modular card frame system designed for signal switching, routing, and distribution in instrumentation and test environments. Card frames of this type serve as the powered backbone for interchangeable function modules — in the Series 2100's case, primarily BNC-terminated signal-routing cards used in video, RF, or analog signal distribution systems. The chassis supplies regulated power and a shared control buss to all installed cards, allowing centralized switching control via the DB9 control buss interface. Systems like the Series 2100 were commonly deployed in broadcast, industrial test, and R&D lab environments during the 1980s and 1990s where modular, reconfigurable signal matrices were needed. Replacement or expansion cards — such as the VSM 21168A visible here — can typically be added or swapped without powering down the frame, making these chassis well-suited to environments requiring flexible, scalable signal routing.
This Sigma Electronics SS-2100-16 Series 2100 16-Slot Powered Card Frame is in used condition. It has been pulled from a working environment and visually inspected. The front blue panel shows light surface wear consistent with normal use. The chassis, backplane, and installed control buss card (2126) appear intact with no obvious physical damage. It has not been powered up or tested at our facility. Please view our photo set and contact us if you have 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.
