8821Q-R Spectrum Analyzer enables cable system operators to put sophisticated analysis and troubleshooting capabilities in the hands of a wider range of technicians.
A portable analyzer designed for use anywhere in the cable network, Trilithic's new 8821Q-R Spectrum Analyzer provides a comprehensive array of digital signal quality tests to give engineers and senior 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.
The color display makes measurement interpretation and analysis simple, shortning the tech learning curve and improving accuracy and productivity.
The 8821Q-R also offers field-friendly ergonomics, a compact size and a long battery life to make field use practical
Priced significantly lower than comparably equipped spectrum analyzers, the 8821Q-R analyzer enables cable system operators to put sophisticated analysis and troubleshooting capabilities in the hands of a wider range of technicians.
