실시간 스펙트럼 분석 이해

2020/09/17, 11:00am PT

실시간 스펙트럼 분석 (RTSA)은 이전에는 하이 엔드 실험실 및 벤치 탑 솔루션에서만 사용할 수 있었던 신호 통찰력을 제공합니다. RTSA를 사용하면 빠르게 변화하는 간헐적인 신호를 끊김없이 캡처하고 표시할 수 있습니다. RTSA의 디지털 특성은 전통적으로 여러 하드웨어 플랫폼이 필요했던 다양한 분석 및 디스플레이 기술을 가능하게 합니다.

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
