phase noise, impulsive noise, R&S®
Key facts
  • Phase noise (10 MHz system bandwidth)
  • User definable phase noise shapes between 0 dBc and -110 dBc
  • Loadable phase noise shapes
  • Impulsive noise with one pulse to 40000 pulses
  • User definable with number of burst pulses, frame duration and pulse distance

Brief description The functional range of the R&S®SMW200A includes a variety of noise sources, such as Additive White Gaussian Noise (AWGN) and in addition, an Extended noise option R&S®SMW-K810 which includes an impulsive noise generator and a phase noise generator. The impulse noise source allows users to define the impulse width, the number and the impulse interval. The phase noise makes it possible to enter directly the reference points of the phase noise trace via table. Users can also load predefined phase noise shapes as waveform files into the R&S®SMW200A for use by the phase noise generator.
