HCU 200 PathTrak

PathTrak provides superior spectrum and QAM analysis capabilities enabling the most efficient and effective monitoring and troubleshooting capabilities. Now fully supported by XPERTrak software, PathTrak is an integral part of the VIAVI Solutions overall HFC maintenance, monitoring, and troubleshooting portfolio.

Live spectrum and QAM analyzers leveraging PathTrak hardware are invaluable for technicians to efficiently resolve issues in the field. Pervasive fast impulse noise must be reliably detected, only PathTrak can adequately address this common use case. Technicians can’t wait 30 seconds or more for feedback from existing polling-based solutions to see the impact on codeword error rates from tightening a connector or wiggling a drop cable, PathTrak’s QAMTrak Analyzers update multiple times per second providing nearly instant feedback.

When the time comes to begin transitioning to Remote PHY, a smooth migration path including continuity of critical HFC maintenance capabilities is ensured through the PathTrak/XPERTrak integration.
