The R&S®FSMR measuring receiver has been specially designed to handle the measurement tasks involved in the calibration of signal generators and fixed or adjustable attenuators. The R&S®FSMR combines the functionality of several instruments in one and is therefore capable of calibrating all vital parameters of a signal generator.

Plus, the R&S®FSMR offers full spectrum analyzer functionality, e.g. for measuring harmonics or phase noise. The base unit does not provide for image frequency rejection in the range above 3.6 GHz since the YIG filters normally used for this would impair level linearity. The optional YIG preselection filter makes the R&S®FSMR a full-featured spectrum analyzer, also in the microwave range. The tracking YIG filter can be switched off for accurate level calibration.
