The Anritsu S331E Site Master is a handheld cable and antenna analyzer built for field installation, maintenance, and troubleshooting of wireless communication systems. Operating from 2 MHz to 4 GHz, it delivers return loss, VSWR, cable loss, distance-to-fault analysis, and Smith Chart measurements in a single portable unit. The 8.4-inch daylight-viewable touchscreen and durable construction enable reliable operation in demanding field environments. Optional 2-port transmission measurement, spectrum analyzer, and power meter configurations extend its utility across multiple test scenarios.
