The JDSU JD786B CellAdvisor RF Analyzer is a portable, field-deployable instrument for installation, maintenance, and troubleshooting of cellular networks from 2G to 4G. It integrates spectrum analysis, cable and antenna analysis, and RF power measurement into a single ruggedized platform, with optional capabilities for optical power measurement, fiber inspection, and CPRI fronthaul interference analysis.
