DEVA Broadcast Radio Explorer

Mobile FM Radio Analyzer

Mobile FM Radio Explorer

The Radio Explorer is a multifunctional, easy to use tool. The design is to evaluate FM broadcast band congestion. It is an excellent tool to measure and also store all important radio broadcast parameters in a Log file. This is a stand-alone solution for running surveys. There are no other additional tools needed. You can setup for observation up to 50 preselected channels. All what you need to do is to get Radio Explorer in the vehicle and go.

When your campaign is over just use the supplied free of charge Windows software to convert the log files into KMZ format and visualize the stored data in Google Earth. Thus you can “get the picture” of what really happens in the field, to outline the coverage of every station compared to competitors’. Such functionality is irreplaceable when you need to analyze and tune your broadcast equipment and antenna. You can export the Log file also as a transitional format for future analysis or keep in record.

LCD Display

With a click on the button the Radio Explorer becomes an excellent tool for analyzing and setup of the whole broadcast equipment on the site. It can measure RF level, MPX deviation, Left & Right Audio levels, RDS and Pilot injection levels. Also, it will display the measurements on large, easy to read LCD display. Easy switching between RDS/RBDS standards and measurement units makes Radio Explorer a suitable choice for broadcast engineers from all around the world.

Moreover, for even better control and data representation connect the device to an ordinary Windows PC, via a USB port. You can choose between various bar-graphs, data plots and histograms. A super-fast band scan mode is available and gives you real-time live visualization of the whole FM band or just a small part of it with down to 5 kHz resolution. Also, all of the device’s or the campaign settings you can do by using software or via very intuitive and sample user interface with 5 buttons and LCD screen.

Data Logger/GPS Receiver

The Radio Explorer incorporates a high quality FM front end with all MPX signal and RDS parameters data logger and high sensitive GPS receiver in reinforced steel box. There is additional MPX input for monitoring as well as MPX output, left and right “program output” and AES/EBU digital audio output. The inputs are for FM, GPS antennas and for power supply. Monitor the program received with headphones plugged into a standard 1/8″ jack with electronic volume control.
