With the new R&S FSWP phase noise tester, users can measure the spectral purity of signal sources such as generators, synthesizers, and voltage-controlled oscillators (VCO) more quickly than with other solutions. The high-end instrument covers a frequency range up to 50 GHz and offers a top dynamic range. The extremely low phase noise of its local oscillator coupled with cross-correlation even makes it possible to measure signal sources that in the past required complex test setups or could not be measured at all.

Thanks to its fully digital signal processing, the R&S FSWP performs complex measurements at the push of a button and features intuitive touchscreen operation. It can quickly and easily measure the phase noise of pulsed sources as well as residual phase noise under pulsed conditions. The R&S FSWP is therefore suitable for both aerospace and defense and automotive applications—that is, for manufacturers of radar components and synthesizers. Thanks to its additional voltage sources, the R&S FSWP is also suitable for measuring VCOs in research and development and, thanks to its high measurement speed, also in production.

The R&S FSWP can be upgraded to a signal and spectrum analyzer.

Rohde & Schwarz is offering an exclusive preview of the new R&S FSWP phase noise and VCO tester at IMS 2015 in Phoenix, AZ. The R&S FSWP8 and R&S FSWP26 models for the 8- and 26-GHz frequency ranges will be available from Rohde & Schwarz in late summer 2015; the R&S FSWP50 model for up to 50 GHz in fall 2015.
