With the R&S FSMR3000 Rohde & Schwarz has developed a microwave measurement receiver to calibrate signal generators and attenuators with one single instrument. The most important features provided by this receiver are tuned RF level measurements, level measurements, analog modulation, and spectrum analysis. Additionally, the R&S FSMR3000 can be equipped with powerful hardware for a high-end phase noise test supplementary to the standard phase noise test with the spectrum analyzer. It also offers digital and analog modulation signal analysis, 80 MHz analysis bandwidth, analysis of pulses, and VOR/ILS signals. The R&S FSMR3000 is a single box instrument that is designed to reduce the complexity in calibration capabilities for the A&D industry.
