The signal being digitalized in this way, at the input, the equipment acquires measurement reproducibility over time. The powerful accuracy of the digital filters used in this equipment enables the FM multiplex signal components to be accurately and repeatedly reproduced from one device to another.
The incredible processing power of the device enables all measurements to be refreshed simultaneously and synchronously, thereby allowing for detailed readings of all the Multiplex FM signal components. The DEVA DB4004 has an easy to read, high-resolution OLED graphical display and ultra-bright bargraph LED 60 segment indicators that allow reading the main signal parameters at a glance.
The built-in DEVA DB4004 Oscilloscope represents the observed signal change, over time and helps you visualize the most important signals participating in the process of demodulating and stereo decoding. Complimenting the Oscilloscope mode, the Spectrum analyzer mode allows spectral analysis of the input signal and some of DB4004 features likewise. Spectral components of the selected signal are determined on the basis of Fast Fourier Transform. MPX Power and all other level measurements are supported by measurement history data. In addition to the list of DB4004 features, RDS information contained in the processed MPX signal is easily visualized and represented as RDS/RBDS Data and detailed RDS/RBDS Statistics.
