FS-SNS Smart noise source, from 10 MHz up to 110 GHz
R&S FS-SNS Smart noise source, key facts.
• Frequency range: 18, 26, 40, 55, 67, 90 or 110 GHz
• Supported by FSW, FSV3000, FSVA3000, FPS, FPL1000, FSWP FSMR3000 & ZNL
• Automatic loading of ENR table
• ENR uncertainty and reflection coefficients table for automatic uncertainty calculation
• Automatic temperature readout for improved accuracy
The FS-SNS smart noise sources enable simple and accurate noise figure and gain measurements by automatically loading all necessary parameters and taking the environmental temperature into account. Measurement uncertainty is calculated automatically and can even be displayed on the result screen.
Available models:
• FS-SNS18: 10 MHz to 18 GHz
• FS-SNS26: 10 MHz to 26,5 GHz
• FS-SNS40: 100 MHz to 40 GHz
• FS-SNS55: 100 MHz to 55 GHz
• FS-SNS67: 100 MHz to 67 GHz
• FS-SNS90: 60 GHz to 90 GHz
• FS-SNS110: 75 GHz to 110 GHz
To perform noise figure and gain measurements with a spectrum analyser, an excess noise ratio (ENR) source is needed that adds a well-defined (and ideally “white”) noise to the input of the DUT. The FS-SNS smart noise sources provide the ENR tables and environmental temperature to the spectrum analyser in electronic format. It is connected to the analyser via a 7-pin cable for power supply and control interface. An adapter cable is available (option) for instruments not equipped with the necessary connector. When connected to a spectrum analyser equipped with the application firmware FSx-K30 noise figure measurements, the instrument handles all needed parameters automatically.
