The Avionics TDR is designed specifically for testing and fault locations on aircraft wiring. The Step TDR Technology is ideal for troubleshooting all types of coax, twisted pairs, single wires in a harness, and aircraft power cables.Whether testing a new harness for complete connections or aging aircraft wiring, this TDR will provide the most accurate trace of the cable’s impedance over length and detect even the smallest faults. The kit includes ETDR PC Vision(c) software for trace documentation and new avionics training presentations.This E20/20B Network TDR with VDV/RF Option (EDMO# 6021-5053) includes an RJ45 to Telco Clips (2 pair) test lead, a BNC to Alligator Clips test lead, TDR PC vision software, app notes, training PPT, an operating manual and literature backup on CD, a printed basic guide, an AC Adapter (100-240 VAC, 50/60 Hz), a DC vehicle adapter, a belt case, a soft carrying case, a USB cable, an internal battery recharger, and 8 AA NiMH batteries installed.
