WebApr 11, 2024 · Q4:扫描模式的选择:sweep还是fft? A:现代频谱仪的扫描模式通常都具有sweep模式和fft模式。通常在比较窄的rbw设置时,fft比sweep更具有速度优势,但在较宽rbw的条件下,sweep模式更快。 WebThe FFT returns a two-sided spectrum in complex form (real and imaginary parts), which you must scale and convert to polar form to obtain magnitude and phase. The frequency axis is identical to that of the two-sided power spectrum. The amplitude of the FFT is related to the number of points in the time-domain signal. Use the following equation to
