IT-084 TDR Cable Reflectometer
The IT-084 TDR Cable Reflectometer is a configuration of the IT-08 Multifunction TV Meter comprised of MB-08 Base Unit and MC-084 Removable Module. IT-084 ensures identification and precision fault location in coaxial cables. Moreover, the Meter allows measurement of cable length and propagation velocity factor. IT-084 employs TDR (Time Domain Reflectometry) technology based on electric pulse sending along the cable and detecting the reverse reflected signal (reflections from any discontinuities such as termination, cable break, which may affect wave impedance of the cable under test). The shape analysis and accurate time measurement from the original pulse to the reflected pulse allows for the identification of fault type as well as fault location (in the cable).
IT-084 KEY FEATURES:
- lightweight and compact handheld design
