Deva DB45

DSP-Based FM Radio Receiver and Modulation Analyzer

All DEva DB45 models come now with the latest update - a Loudness Meter, adding another superb feature to an already impressive list. What is more, average program loudness measurements can be shown as defined by ITU BS.1770-4 and EBU R128 recommendations – the product supports both. Thanks to our team of engineers who work tirelessly to keep improving the solutions provided by DEVA, the DB45 adds another hugely important functionality to its set, which is sure to tip the scales in its favor, definitely making it the right choice of FM monitoring receiver for you.

Maintaining the high standards of the DEVA product range, the Deva DB45 model is the very definition of reliable monitoring of the FM signal. With a compact and practical design, it incorporates a variety of features spelling accurate and dependable measuring of the signal parameters, including the RF level, MPX deviation, MPX power, Left & Right audio levels, RDS, and Pilot injection levels.

The Deva DB45 boasts a fully DSP-based core and guarantees round-the-clock operation. Upon demodulation of the FM signal, the RF signal is digitalized by the SDR FM tuner and all signal processing is achieved through calculations. The precision of this tool's digital filters means that the FM Multiplex signal's components can be accurately and repeatedly reproduced from one device to another, i.e. the same signal applied to two devices would give the same result. All measurement can be refreshed simultaneously and synchronously so that detailed readings of the Multiplex FM signal components can be obtained.

The Deva DB45 supports TCP/IP and optional GSM connectivity, allowing for easy monitoring of the channel status and listening to real-time audio no matter where you are - all that is required is a mobile phone. Another impressive feature of this tool is the built-in audio streamer which gives users the opportunity to listen to and record the audio from any station.

The Deva DB45 model provides an RDS/RBDS decoder with BER meter, as well as adjustable alarms for RF, deviation, Pilot and RDS signal via email, SMS and SNMP, while the WEB interface makes for easy set-up and control of your unit.

The Deva DB45 is an indispensable piece of equipment when it comes to accuracy and reliability. Coupled with an affordable price, all its features contrive to produce an impeccable monitoring performance.
