AxelTech Wolf 1MS/2MS
Wolf 2MS and 1MS are state-of-the-art FM Radio Monitoring devices, designed to control the signal presence and quality over an FM Distribution Network. Onboard twin tuners allow to accurately scan frequencies, they offer high performances in FM reception, MPX audio encoding and RDS data streaming. This cutting-edge equipment features three main operating modes: continuously reception, bandscan and smart bandscan. With FM static mode the user can focus on a single channel, selected and monitored exclusively. Thanks to the scan mode up to 32 channels for each tuner can be scanned and supervised in a single analysis. FM static mode also receives up to 64 memories. Wolf 1MS and 2MS allow to manage accurately RF, MPX, RDS, Audio and RDS data dynamic services. In smart mode the channel scan time is adjusted automatically according to instantaneous measurements requirements
