WisyRDS  is flexible toolkit for AM/FM/RDS signals modulations addressed to receivers manufacturing test equipment as well as R&D product validation tests.

WisyRDS package includes also a complete set of NI LabVIEW® VIs and source code examples of common radio applications. This set allows the user to easily integrate AM/FM/RDS modulations functionalities into NI LabVIEW® applications to create dedicated RF tests.

WisyRDS supports a widely selectable formats of audio signals  and all most common RDS features such as Radiotext (RT), Enhanced Other Network, and Alternative Frequencies (AF).

The RDS/RBDS signals are generated according to the European standard "IEC/CENELEC 621061" (RDS) and the American "NRSC-4-A United States RBDS Standard" (RBDS).

WisyRDS is compliant with the WisyPLAY kit composed by the NI PXI-5610 RF Upconverter and the NI PXIe-5641R IF Transceiver.

The Signal waveforms are stored and played according to the signal format created by the user within the modulation framework in single or loop play.

  • WisyRDS creates AM/FM/RDS/RBDS signals through a user-friendly NI LabVIEW based API.
  • The generated waveforms can be stored and played with WisyPLAY dual-RF Generator.
  • The signal configuration (e.g., FM deviation, RDS groups) can be programmatically modified by the user application
