Trilithic 8821Q

Complete set of spectrum analysis tests in one instrument
Intuitive user interface for shorter learning curve
Full-featured, high performance, low-cost analyzer alternative for tight budgets
Automated FCC proof testing to simplify technician’s task

The productivity solution for headend and high-tier techs.

A portable analyzer designed for use anywhere in the cable network, Trilithic’s new 8821Q Spectrum Analyzer provides a comprehensive array of digital signal quality tests to give headend and elite techs an advantage in alignment, troubleshooting and proof of performance testing.

Thanks to DSP technology, the system can make a wide range of precision measurements with exceptional speed – including QAM, MER, pre and post FEC BER, equalizer tap graph, in-channel frequency response, and group delay.

Priced significantly lower than comparably equipped spectrum analyzers, the 8821Q analyzer enables cable system operators to put sophisticated analysis and troubleshooting capabilities in the hands of a wider range of technicians.
