Deva Broadcast Radio Explorer – Mobile FM Radio Analyzer
Radio Explorer is a multifunctional, easy-to-use tool, designed for the FM to measure and store all important parameters in a log file. Like a stick mask measurement. You can set up to 50 pre-selected channels to monitor. When the measurements are done you can convert the log files into KMZ format and visualize the stored data in Google Earth. So you can “get a picture” of what’s really happening in the field, to outline the coverage of each station compared to competitors. Such functionality is irreplaceable when you need to analyze and tune your broadcast equipment and antenna. The log file can also be exported as a transition format for future analysis or for tracking purposes.
With a click on the button Radio Explorer becomes an excellent tool for analyzing and setup of whole broadcast equipment on the site. It can measure RF level, MPX deviation, Left & Right Audio levels, RDS and Pilot injection levels and display the measurements on large, easy to read LCD display. Easy switching between RDS/RBDS standards and measurement units makes Radio Explorer compatible for use by broadcast engineers from all around the world. For even better control and data representation connect the device to a usual Windows PC, via a USB port. You can choose between various bar-graphs, data plots, histograms and etc. A super-fast band scan mode is available and gives to you real-time live visualization of whole FM band or just small part of it with down to 5 kHz resolution. All of device or campaign settings you can do by using software or via very intuitive and sample user interface with 5 buttons and LCD screen.
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. Additional MPX input is available for monitoring as well as MPX output, left and right “”program output”” and AES/EBU digital audio output. Inputs are for FM and GPS antennas and for power supply. The program received can be monitored with headphones plugged into a standard 1/8″” jack with electronic volume control.
