Technical specifications of the R&S®FSWP phase noise analyzer and VCO tester.

This document provides the technical specifications of the R&S®FSWP phase noise analyzer and VCO tester.

The R&S®FSWP phase noise analyzer and VCO tester features very high sensitivity thanks to extremely low noise internal sources and cross-correlation. It can measure phase noise on highly stable sources such as those found in radar applications in just seconds. Additional options such as pulsed signal measurements, residual phase noise characterization and integrated high‑end signal and spectrum analysis make the R&S®FSWP a unique test instrument. A multitouch display ensures straightforward and intuitive operation. The embedded SCPI recorder enables easy creation of executable scripts.

The R&S®FSWP phase noise analyzer and VCO tester is a high-end instrument that accurately analyzes noise in key radar and communications system components.

This paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for example for automotive RADAR sensors at 80 GHz using the interferometric measurement approach in combination with a phase noise and VCO tester R&S FSWP. The setup provides a way to characterize the additive/residual phase noise of amplifiers down to -150 dBc/Hz at 100 kHz offset even in the microwave range at 80 GHz.
