The R&S®DDF255 combines the extremely powerful R&S®ESMD wideband monitoring receiver with the accurate correlative interferometer DF method. This combination yields a high-precision wideband direction finder featuring extensive measurement and analysis functions. With its high integration density and optional DC power supply, the R&S®DDF255 is also ideal for mobile applications.
This application brochure describes the sophisticated digital signal processing implemented in all modern Rohde&Schwarz receivers. The implementation is optimized for applications such as detecting unknown signals, identifying interference, spectrum monitoring, spectrum clearance, signal search over wide frequency ranges, producing signal content and direction finding of identified signals. The advantages of digital signal processing for radiomonitoring operators in their daily work are also explained.
