Product Overview

The 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 FSU fully meets these requirements.

Its wide dynamic range makes the 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 FSU is the ideal instrument for measurement tasks in RADAR development and when searching for spurious emissions.

A full choice of detectors for adaptation to a wide range of signal types, versatile resolution filters and additional applications make the FSU a multi-purpose easy-to-use measurement tool.
