OBSERVA Field Monitor Professional USB Receiver for Digital Radio OBSERVA Field Monitor is a compact, robust USB-powered receiver that provides detailed views of the DAB/DAB + ensemble and RF transmissions, including SFN Networks. Ensemble displays include audio and data services e.g. DLS, Slideshow, EPG. RF displays include signal level/field strength, TII decoding, modulation, including Channel Impulse Response, Phase Reference and constellation diagram. The Field Monitor enables users to create custom monitoring and logging interfaces that contain only the metrics that are required. This combination of customisable displays, real-time graphs and wide range of metric measurements gives users the most versatile tool for accurate and informative field measurements. The FM Monitoring option displays Receiver Metrics, Radio Text statistics, RDS Flags and Group Counts. Graphical displays are provided for Signal Level, Multiplex Power, Block Error-Rate, FM Spectrum and Audio Spectrum. For mobile measurements, map information can be cached prior to starting the journey. This allows for viewing real-time location and metrics without the need for an always-on internet connection. Multiple profiles can be created for storing selected metrics. These profiles can be saved and loaded into the software as required.
