Brief Description

The R&S®FSU is a high-performance spectrum analyzer with outstanding performance in phase noise, dynamic range and measurement accuracy that meets any challenge in RF analysis – in aerospace and defense or for general microwave applications up to 67 GHz.

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.
