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.
