The Triplett RWV10G Real World LAN and Cable Verifier is break-through technology that brings cable and network verification and testing to a whole new level of reality. Unlike traditional testers, the RWV10G uses digital circuitry and digital testing techniques to perform its tasks. It works with UTP and all Ethernet devices. These tests include traditional TIA568 cable verification (length, opens, shorts, split pairs, wire map) for UTP (unshielded twisted pair). Plus RWV10G's own sophisticated crosstalk, timing and cable parameter tests that yield a UTP cable's category (CAT3, CAT5, CAT5E, CAT6, CAT7) and speed capability (10M, 100M, 1G, 10G). In addition, the RWV10G can use your own network devices (hubs, switches, PCs) to test UTP cables with live data and, the RWV10G analyzes links and data from all types of hubs, switches and PCs. It performs both single sided tests for advertised speed (10M, 100M, 1G, 10G and duplex) and inline tests (between devices) for negotiated speed. The engine of the RWV10G circuitry is capable of 1 nanosecond resolution. It also works with coax cable and can test for the length of the cable, opens, shorts, wiremap and distance to any faults that might exist. As with UTP, coax can be toned with the toner feature and test results can be stored for later printing in the RWV10G's memory.
