Y-Adapter
Description
The Model CS-1279 is a three-slot male triaxial to dual three-lug female triaxial tee. This 50 Ω BNC three-port
Y-shape adapter allows routing of a signal from a common source to two different devices. The combination of
two BNC jack interfaces and one BNC plug interface is useful for mating in many commonly found test
applications.
This Y-adapter allows signal splitting to two devices that is useful in confined spaces. Also, the nickel-plated
body enhances corrosion resistance.
