The Anritsu Site Master S331E is the eighth-generation compact handheld Cable and Antenna Analyzer, featuring the highest performance and most capabilities ever offered by Anritsu in a compact handheld tester. Designed for installation and maintenance of wireless networks — including legacy, 3G, and 4G infrastructure — it is the preferred tool for wireless service providers, contractors, installers, military, aerospace and defence, and public safety applications.

The S331E eliminates the need to carry multiple instruments by combining cable and antenna analysis, optional spectrum analysis, 2-port transmission measurement, and more in a single rugged field-ready unit. The easyTest Tools feature allows experienced users to create and deliver on-screen work instructions for less-experienced cable and antenna sweepers, improving accuracy and repeatability.
