Designed specifically for aviation applications the Avionics TDR Complete Kit is contained in an ATA-3000 Class 1 carrying case. The custom foam is designed to hold the E20/20 TDR and accessories securely to prevent FOD and the lid label provides a clear indication of what item should be in every foam cut-out location. The E20/20 TDR has both BNC and RJ-45 test ports and an aviation customized cable list in the memory. The list provides quick access to a variety of common aviation coax, twisted pair and single-wires' impedances and velocity factors.
