The use of Tower Mounted Amplifiers (TMAs) in cellular, PCS, GSM and 3G Base Stations has offered significant improvements to carriers to minimize call drops, loss of communication, and provide a more reliable service to customers in both outdoor and indoor coverage. Their use with any new installation is another way to provide better coverage and increase the number of subscribers without deploying new Base Stations in the same geographic area. This application note will focus on testing of TMAs before and after installation and provide diagnostic tests like Cable Loss and DTF-Load Sweep to help determine the performance of transmission lines and tower mounted amplifiers. Site Master S251C simplifies performance verification of TMAs prior to installation, thus reducing trouble shooting time and future diagnostics checks. Its easy calibration, high dynamic range, user-friendly menu, and optional bias tee provides a simple method of measuring gain of tower mounted amplifiers in the field.
