Emerging RF technologies require a flexible and easily expandable platform to keep pace with changing standards and requirements. Through the power of National Instruments RF software, the PXI RF platform provides access to customizable functionality not available in traditional instrumentation, such as:

  • Custom modulation measurements
  • Joint time-frequency analysis
  • Continuous signal acquisition

Common Analysis Algorithms

Occupied Bandwidth - Occupied bandwidth is a measurement of a frequency band's bandwidth that contains a specified percentage of the total power of the signal.

Peak Search - A spectral peak search algorithm determines the levels and frequencies of peaks in a specified band. The algorithm uses interpolation to precisely locate frequency peaks in the amplitude or power spectrum in any units or scaling.

Power in Band - Power in band measures the total power within any specified frequency range or band.

Adjacent Channel Power - Adjacent channel power measures how a particular channel and its two adjacent channels distribute power. This measurement is performed by calculating the total power in the channel and also the total power in the surrounding upper and lower channels.
