Vector signal analyzers (VSAs) are a popular choice for analyzing modern communication systems because of the advantages they offer over traditional spectrum analyzers. As the name suggests, VSAs … WebDuring FFT analysis it can be beneficial to extract the energy content from fixed frequency ranges/sections of interest. This is also referred to as a type of frequency domain filtering. Some FFT analyzers support the ability to produce derived scalar channels that output one value per produced spectrum.
