Test & Measurement R&S®FSU Spectrum Analyzer High-end spectrum analysis

R&S®FSU Spectrum Analyzer At a glance To handle the wide variety of measurement tasks in product development, an instrument must offer ample functionality and excellent performance in all areas of interest. The R&S®FSU fully meets these requirements. Its wide dynamic range makes the R&S®FSU an ideal tool for base station development and testing. That plus the excellent characteristics already incorporated in the standard model, e.g. < 0.3 dB total measurement uncertainty, gated sweep and IF power trigger. Due to its low phase noise and low noise floor, the R&S®FSU is the ideal instrument for...
