Field Monitor (H-FMON)

The RadioScape Field Monitor is a fully portable Test unit designed as a fully featured, Eureka-147 DAB monitoring receiver working in both Band III and L-Band and delivering functionality for DAB / DAB+ / T-DMB / DMB-A ensembles to obtain a wide range of metrics for individual Transmitters and SFN networks

To enable Broadcasters, Regulators or Service providers to accurately monitor, and log a wide range of metrics from a full ensemble and log (in CSV format) against accurate GPS data to enable sophisticated plots to be produced "back at base".

Amongst the many metrics available are Bit Error rate and Field Strength, - hence delivering a very powerful tool to assist in Network planning and on going management.

The units optional SFN functionality (S-SFNM) delivers (without the need for external reference signals) a wide range of metrics that combine to deliver an extremely strong engineering tool.

Additional options for DAB+ and a "DMB viewer" can combine in the highly portable unit to present one o the most powerful, portable Eureka 147 Broadcast monitors on the market today. Amongst the many metrics the unit delivers are the following:
