DB45 – Compact FM Radio Receiver

DSP-Based FM Radio Receiver and Modulation Analyzer

The DEVA Broadcast DB45 model is the very definition of reliable monitoring of the FM signal. This equipment has a compact and practical design. It incorporates a variety of features spelling accuracy and dependable measuring of the signal parameters. This includes the RF level, MPX deviation, MPX power, Left & Right audio levels, RDS, and Pilot injection levels.

DB45 Multiple Functions

The DEVA Broadcast 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. 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. More so, it means the same signal applied to two devices would give the same result. All measurements can be refreshed simultaneously and synchronously which makes for detailed readings of the Multiplex FM signal components.

Other Support Functions

The DEVA Broadcast DB45 supports TCP/IP and optional GSM connectivity. It allows for easy monitoring of the channel status and listening to real-time audio no matter where you are. However, you only require a mobile phone. Another impressive feature of this tool is the built-in audio streamer. Users have the opportunity to listen to and record the audio from any station.

RDS/RBDS Decoder

The DEVA Broadcast DB45 model provides an RDS/RBDS decoder with a BER meter. It also has adjustable alarms for RF, deviation, Pilot and RDS signals via email, SMS and SNMP. Interestingly, the WEB interface makes for easy set-up and control of your unit.

The DEVA Broadcast DB45 is an indispensable piece of equipment when it comes to accuracy and reliability. This equipment is considerably affordable. Moreover, all its features contrive to produce an impeccable monitoring performance.
