Understanding Real-Time Spectrum Analysis

17/09/2020 , 11:00am PT

Real-time spectrum analysis (RTSA) provides signal insight previously only available in high-end lab and benchtop solutions. RTSA allows gapless capture and display of rapidly changing and highly intermittent signals. The digital nature of RTSA also makes a variety of analysis and display technologies possible that traditionally required multiple hardware platforms.

This webinar will provide a basic understanding of what differentiates Real-time spectrum analyzers from traditional analyzers; give insight into how the digital FFT processing works; the drawbacks of digital FFT processing and how those are overcome in modern RTSA implementations; and provide an overview of how real-time high speed displays are created to provide insight into signals that change so fast it is beyond the capabilities of the human eye to observe.

Key Topics:

  • Comparison of traditional spectrum analyzer architectures to that of the RTSA
  • Provide an overview of the Fast Fourier Transform (FFT)
  • Discussion of FFT windowing, why it is necessary, and how it is used accurately represent signals
  • Presentation of the key RTSA specifications, how they are defined, and why they are important
  • Description of key display techniques that exploit the nature of the RTSA and make it possible for the human eye to capture fast changing signals
