The Anritsu Site Master S331D is a rugged handheld cable and antenna analyzer designed for installation, maintenance, and troubleshooting of wireless base station and RF feeder systems. Using Frequency Domain Reflectometry (FDR) techniques, the S331D can detect small degradations in cables, connectors, and antennas before they develop into major failures, helping operators reduce downtime and maintenance costs.
Built specifically for field environments, the S331D features a high-resolution sunlight-readable TFT display, menu-driven user interface, and durable chassis that withstands daily outdoor use. It enables fast and accurate RF measurements directly from ground level, eliminating the need to climb towers for many diagnostic tasks.
