The Anritsu S361E Site Master is a handheld cable and antenna analyzer that delivers comprehensive field diagnostics across 2 MHz to 6 GHz. Purpose-built for wireless infrastructure deployment, maintenance, and fault isolation, the S361E combines single-port and optional dual-port transmission measurements with an integrated spectrum analyzer and optional power meter in a portable 2.71 kg platform. Field technicians deploy it for real-time return loss, VSWR, cable loss, and distance-to-fault analysis using Frequency Domain Reflectometry (FDR) technology.
