The 1270A provides a unique package to the field engineer who needs to find faults on CATV and telecom cables for both outside plant and domestic applications. It is 'housed' in a rugged package with full PC connectivity and Riserbond ease of use. It is the solution for network provisioning. It is intuitive and easy to use and meets the users needs both in performance and in use. It has advanced features such as a sub-ns pulse, CATV and telecom inputs for VoIP applications and auto fault find. It is housed in a field proven rugged and robust enclosure. The 1270A provides the complete fault finding solution for the field engineer.
Combined coax and telco TDR.
Rugged and robust.
Easy to use.
Auto fault find.
Direct connections from both coax andtwisted pair - Superior fault location in avariety of industries and applications. The1270A will directly test coaxial cable andtwisted pair cable by using front panelconnections.
RANGE-PLUS - Two-button operation thatallows the operator to quickly scan the cableunder test while automatically steppingthrough a specific pulse width, vertical gain,and cable length.
2-Line Input - Connect two twisted paircables simultaneously for comparison.
Sub-nanosecond Pulse Width - Pinpointminor faults which interrupt digital servicesand cause signal loss, ingress, and egress.
