Professional Coax Cable Tester – The CableMaster 800 / 850

The CableMaster 800 / 850 is the ideal coax cable tester for professional installers and network operators who are challenged with testing and trouble-shooting coax cable and RJ45 network cable installations.

Product Description

Test Coax Cable & RJ45 Networks with the CableMaster 800 / 850

The CableMaster 800 / 850 is a professional coax cable tester that is equipped with an F-type connector for testing coaxial cables, as well as an RJ45 jack for testing network cables. The CableMaster 800 / 850 verifies the wiremap, determines the cable length and distance to the fault. Results can be saved and then documented using the PC-based reporting software. It offers a multitude of network diagnostic features for trouble-shooting, such as cable tracing, link detection up to 1Gb/s, Ping, network discovery and PoE tests. It verifies continuity, tests for reversals, miswires, split pairs, shorts and opens. With the cable length and distance to the open determined using the integrated Time Domain Reflectometer (TDR).

The CableMaster 800 / 850 coax cable tester has an integrated tone generator to send a modulated audible signal into the cable that can be detected by an optional tone probe and can be used for cable tracing and outlet / port identification.
