A TDR TO FIT YOUR SPECIFIC NEEDS. REVIEW OUR DIFFERENT MODELS AND KITS BELOW.Fault locating for: Opens , shorts, bridged taps, split and resplit pairs, water, chaffing damage, coax crimps and splices, shunt faults, series resistive faults, splitters. Any impedance or loop resistance affecting fault.Micro Fault locating: Two modes designed to pin-point small faults easy to miss on any full TDR trace. Particularly on long coax cables.Stores: 32 Traces and instrument setups. 64 Cable types with their impedance and velocity.Help: Both a Setup Wizard for step-by-step guided startups and one-button context sensitive help for all menus and functions.The E20/20 Step TDR is guaranteed to save time and money by quickly and accurately locating even small cable faults and by not chasing cable faults that don't exist.View the applicable data sheet below for more details and key specifications.
