The Anritsu Site Master S331B and S332B are handheld cable, antenna, and spectrum analyzers designed for measuring SWR, return loss, and cable insertion loss, as well as locating faults in RF transmission lines and antenna systems. Featuring built-in Frequency Domain Reflectometry (FDR) technology, they are optimized for the installation, maintenance, and troubleshooting of wireless communication systems. The S332B model adds spectrum analysis capabilities.
