The Band Scanner 2 is a revolutionary device that builds on the features of the legendary Band Scanner to provide you with the ultimate tool to assess FM broadcast band congestion and log station identification parameters. In keeping with the characteristics of its famous predecessor, this impressive tool can measure RF level, MPX deviation, Left & Right Audio Levels, RDS and Pilot injection levels. During a campaign, measurements are stored in a log file, after which they can be easily converted into KMZ format and visualized in Google Earth.
To power the system, all you need is the USB port of any Windows PC. With the Band Scanner 2 you can view playlists of the competitive stations, as well as save and export them into and Excel file. The free-of-charge Windows software sweeps the receiver across the FM band and generates a spectrum display of carrier level versus frequency. Each carrier is analyzed and a station list is created. This sophisticated product further refines stations with an RDS presence to show all radio data groups transmitted. It allows for manual tuning through the receiver screen or by double-clicking a point on the spectrum plot or an entry on the station list. There are two ways to save spectrum plots – as jpeg or bmp files. A separate window on the receiver screen displays the RDS data error level.
To proste, ale wielofunkcyjne urządzenie: mierzy poziom RF, dewiację MPX, moc MPX, poziomy audio kanałów L i P, poziom pdnośnej z kodera stereo. Wyniki pomiarów są stale i synchronicznie odświeżane pozwala to na szczegółowe odczyty wartości składników sygnału FM. Z DB44 można połączyć się poprzez Ethernet i opcjonalnie modem GSM, co umożliwia monitoring sygnału i odsłuch audio stacji w dowolnym miejscu i z użyciem (prawie) dowolnego smartfonu.
