To certify Ethernet speed performance of cable runs, the Validator series handheld testers conduct Bit Error Rate (BER) tests by sending data packets down specified cable runs at defined data rates to check for errors at the maximum throughput of the link. Both Validator and Validator-NT also report on signal quality that can impact high-speed data transmission by measuring signal-to-noise ratio (SNR). Skew mea­surements report on the signal time delay between pairs that can impact Ethernet data transmission. Finally, the Validator series units provide continuity testing that detects opens, shorts, miswires, split pairs, reversals, and high-resistance faults while accurately measuring distance to faults and total cable length.

The Validator-NT includes a comprehensive set of features to test the active network capabilities of a network: port discovery for speed and capability detection of active devices up to 1 Gb/s; ping test to verify connectivity to IP hosts on or off the local network; and discovery of network devices using Cisco Delivery Protocol (CDP). Cabling Installation and Planning Software Validator and Validator-NT include the powerful Plan-Um® planning and reporting software for planning network architectures and organizing cable information and test results. Plan-Um helps set-up each job, defines scope of the job, aids in testing cable runs, and produces reports for the installer and customer. The Network Tools feature provides a quick way to see the network architecture and a way to document moves, adds, and changes. Used in conjunction with Plan-Um, Validator and Validator-NT provide confidence in the physical properties of cable runs and the overall capability of the network.
