The Deva Radio Explorer II is a full-featured device designed to cater for all market requirements. This easy for use mobile tool evaluates the FM broadcast band congestion and stores all important radio broadcast parameters in a Log file. The built-in FTP system allows downloading and managing of the files through DEVA Device Manager Software. The fully DSP- based FM radio frontend tuner utilizes the latest technologies in the DSP processing of the FM signal.
The Dual DSP-based, compact and affordable Radio Explorer II is a product of highly valued performance. This device is the perfect solution for field surveys and on site monitoring of station complete signal. With just a click on the button, Deva Radio Explorer turns into an excellent tool for analyzing of the signal strength and quality after repairs or set-up of new equipment. This cost-effective device can measure RF level, MPX deviation, Left & Right Audio levels, RF field strength, RDS and Pilot injection levels. All measurements are visualized on easy to read OLED Graphical display.
Designed for signal surveillance on the field where the listeners are, all that is needed is a vehicle and Radio Explorer II. There are two campaign modes:
- Deva Radio Explorer II can be set to measure automatically one or multiple preselected frequencies (Up to 50);
- RDS PI / RBDS Call campaign – up to 10 stations can be chosen. Radio Explorer II will automatically detect the used frequency. While the campaign is running, the chosen stations will be monitored; Radio Explorer II will automatically switch between the variable frequencies during movement – just as the car radio of your listeners.
When the campaign is over, using the supplied free of charge Windows software the log files could be converted into KMZ format and visualized in Google Earth. Such functionality is irreplaceable when current information of the FM broadcast band congestion and coverage is needed. As an addition, the Log file can be also exported and saved as a transitional format for future analysis.
The band scan mode guarantees real-time live visualization of either the FM band or a particular predefined part of it with down to 10 kHz resolution. Deva Radio Explorer II can be controlled through:
- The built-in Web server – a standard web browser can be used to monitor its status or to make some adjustments. iOS and Android devices are also supported. The Main Screen of the WEB Interface shows all mandatory parameters represented as LED bar graph readings;
- The supplied free of charge DEVA Device Manager Software – the easy-to-use interface allows quick and easy connection to the device. The dedicated module ensures managing of all the device’s logs and displays respectively all the events in a handy manner;
- The very intuitive user interface with OLED screen, Front panel navigational and soft buttons ensures an easy usage of the device’s build-in features.
Supporting both RDS/RBDS standards and measurement units, the Radio Explorer II is a suitable choice for broadcast engineers from all around the world. The device offers various bar-graphs, data plots, histograms, etc. therefore it will meet the expectations of the most demanding broadcasters.
The Radio Explorer II comes with both Car Cigarette Lighter adapter and 240 AC/12DC (2A)
with XLR connection PSU.
