The Viavi Trilithic TDR DSP is a professional time-domain reflectometer engineered for cable television and HFC network technicians. It is designed to quickly and accurately locate faults including shorts, opens, water ingress points, and impedance mismatches within coaxial cable infrastructure, helping to minimise downtime and improve plant reliability.

The TDR DSP uses digital signal processing to deliver high-resolution, accurate distance-to-fault measurements across a wide range of cable types. Its rugged, portable form factor makes it well suited for field deployment, and it is typically paired with a high-frequency probe such as the I-STOP 1.2 GHz probe for precision measurements.

Key capabilities include:
TDR Technology: Digital signal processing-based time-domain reflectometry
Fault Detection: Locates shorts, opens, water ingress, and impedance mismatches
Probe Compatibility: Compatible with I-STOP 1.2 GHz probe for enhanced performance
Portability: Rugged, field-ready design with protective carry case
Display: On-screen waveform representation of cable reflections
