        The Crestron MM-HTDR MediaManifold™ Cable Analyzer is a portable handheld device used to determine the length and integrity of RG6 cable runs. Using "time domain reflectometry," the MM-HTDR can measure cable lengths up to 1099 feet. When used in conjunction with the MM-DS-12 MediaManifold CATV Distribution System, the MM-HTDR can be used to set the optimum gain and tilt settings for each zone based on the length measured (up to 300 feet maximum). The MM-HTDR can also be used to determine if a cable is shorted. Single-button operation makes it simple to set up a complete MediaManifold system.
