The Anritsu S331D Site Master Cable and Antenna Analyzer's Frequency Domain Reflectometry (FDR) techniques break away from the traditional fix-after-failure maintenance process by finding small, hard to identify problems before major failures occur.

Sixty to eighty percent of a typical cell site's problems are caused by problematic cables, connectors and antennas. When cables or antennas are contaminated with moisture, damaged, or mispositioned during storms, the Anritsu S331D Site Master identifies the problem quickly. Antenna degradation reduces the cell coverage pattern and can cause dropped calls. Site Master can pinpoint the antenna problem from ground level in a few seconds making climbing the antenna tower unnecessary. A poorly installed weather seal will corrode connectors and, if undetected, will eventually damage an expensive coaxial cable. The Anritsu S331D Site Master has the sensitivity to identify the connector problem before the cable is damaged. Distance-To-Fault provides the clearest indication of troubled areas.


Function Benefits
Cable and Antenna Analyzer Characterize antenna system and pinpoint location of faults
Standard TFT Color Display Display is viewable in direct sunlight
Power Monitor Performs accurate broadband power measurements using an external detector
Power Meter Performs accurate power measurements up to 3 GHz without the need of an external detector
GPS Receiver Provides location (latitude, longitude, altitude) and UTC time information
T1/E1 Analyzer Simplifies the task of determining if the source of problems is on the wireline or the wireless side
