Rohde & Schwarz FSMR-series Measuring Receivers 20 Hz – 50 GHz
Description
Rohde & Schwarz FSMR-series Measuring Receivers 20 Hz – 50 GHz offer full spectrum analyzer functionality, e.g. for measuring harmonics or phase noise.
The R&S®FSMR-series combines the functionality of several instruments in one and can calibrate all vital parameters of a signal generator.
The base units do 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.
