SC-QAM Troubleshooting Masterclass: MER, BER, and Constellations Explained (with Ron Hranac)

Описание: Join Brady Volpe and Ron Hranac as they take a technician-level look. Educate cable broadband technicians and engineers on how to effectively use a QAM analyzer to diagnose and resolve issues with SC-QAM (Single Carrier Quadrature Amplitude Modulation) channels in the HFC plant or CMTS environment. If you’re a cable tech, broadband engineer, or just a DOCSIS nerd, this is the livestream for you.

Struggling with pixelation, slow speeds, or downstream signal issues? In this video, we show broadband technicians how to troubleshoot SC-QAM channels using a QAM analyzer. Learn how to read key metrics like MER, BER, and constellation diagrams to quickly identify and resolve common HFC plant impairments. Whether you're in the field or headend, this guide helps you keep DOCSIS networks running smooth.
