描述
Maintaining the high standards of the DEVA product range, the 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 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 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 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 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.
