Anritsu's precision Area Scanners focus on optimization in densely populated areas where analysis of multiple paths and interference are critical. There are versions suitable for indoor measurement and network maintenance, as well as versions with no display that are optimized for drive testing. Key features include long battery life, real-time measurements using high speed sampling for accuracy, stable measurement algorithms to test fading and the Doppler effect, optimized circuitry to avoid the effects of interference, and precise data collection in complicated multi-path environments.
