The Viavi (formerly JDSU) JD723C CellAdvisor is a rugged, handheld base station analyser designed for field technicians working on cellular infrastructure installation, commissioning, and troubleshooting. It combines cable and antenna analysis with RF spectrum analysis in a single portable platform, enabling engineers to perform comprehensive site verification without carrying multiple instruments.
The JD723C supports a wide range of measurements including return loss, VSWR, cable loss, distance-to-fault (DTF), and 1-port S-parameter measurements, making it well suited for verifying antenna systems and feedlines on cellular base stations.
