The Cable Mate is a precision hand held return loss/SWR and fault location measurement instrument. Built-in fault location and wattmeter capabilities are available if required, allowing users to configure Cable Mate to meet their specific need. It's lightweight, rugged design, and wide temperature range make it ideal for field applications. Cable Mate's frequency domain reflectometry technique allows it to find problems before they became catastrophic faults. Advanced features such as distance-to-fault windowing functions are incorporated in the Cable Mate design.
