Rohde & Schwarz Unveils New Microwave Measurement Receiver

Rohde & Schwarz has introduced new microwave measurement receiver, R&S FSMR3000, to calibrate signal generators and attenuators with one single instrument.

Rohde The most important features provided 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 offers also digital and analog modulation signal analysis, 80 MHz analysis bandwidth, analysis of pulses and VOR/ILS signals. The R&S FSMR as a single box instrument is designed to reduce the complexity in calibration capabilities for the A&D industry.

Along with level calibration, the microwave measurement receiver provides analog AM, FM and φM modulation analysis.

The R&S FSMR3000 is designed to make the signal generator and attenuator calibration less complex and includes features that make calibrating lab test processes easier.

The 8 GHz, 26.5 GHz and 50 GHz instruments provide all necessary measurement capabilities in a compact single box instrument.

The high dynamic range of the R&S FSMR has a level measurement range of -152 to +30dBm. The low linearity uncertainty in the instrument of ± (0.009 dB + 0.005 dB per 10 dB step) together with absolute power sensor calibration provides highly accurate signal level measurements, where the R&S NRP50T can cover the whole frequency range from DC to 50 GHz.

Built-in analog modulation analysis is available for AM, FM, and φM modulation measurements. AM modulation depths from 0 to 100% and FM frequency deviations as wide as 16 MHz can be measured.

The instrument has a 16-bit AD converter with 200 Msamples/s for modulation analysis with an internal signal analysis bandwidth of up to 80 MHz. If the analysis option is installed, modulation measurements on digitally modulated signals are also possible.

Pulses can be automatically analyzed. No additional vector signal analyzers are needed to measure the performance of these signals.

VOR (VHF Omnidirectional Range, an on-course radio beacon) and ILS (Instrument Landing System, for guidance during approach and landing) are air traffic navigation aids based on amplitude modulated signals and require very accurate and reliable modulation measurements.
