To certify Ethernet speed performance of cable runs, the ValidatorPRO series of handheld testers conducts 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. The ValidatorPRO also reports on signal quality that can impact high-speed data transmission by measuring signal-to-noise ratio (SNR). Skew measurements provide the signal time delay between pairs that can impact Ethernet data transmission. The ValidatorPRO also provides 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 ValidatorPRO includes an integrated optical power meter that measures optical power at 850/1300/1310/1490/1550 nm on multimode or single-mode fiber to address an increasing number of Ethernet networks that now include optical links.
The ValidatorPRO-NT version includes a comprehensive set of features for testing a network s active network capabilities: measure Power over Ethernet (PoE) to ensure the correct power is available on the correct pins, use port discovery to ensure the correct speed and duplex capability are available; connect at gigabit Ethernet and run ping tests to verify connectivity to IP hosts; discover network devices using Cisco Discovery Protocol (CDP) or Link Layer Discovery Protocol (LLDP), discovery and display essential information regarding functionality and configuration of 802.11 b/g/n networks.
