The new phase noise analyser and VCO tester from Rohde & Schwarz enables ultrasensitive and ultra-fast phase noise measurements. The R&S FSWP also allows users to very easily measure pulsed sources and residual phase noise of RF components. Plus the instrument can be upgraded to a signal and spectrum analyser.

With the new phase noise tester, users can measure the spectral purity of signal sources such as generators, synthesisers and voltage-controlled oscillators (VCO) more quickly than with any other solution.

The high-end instrument covers a frequency range up to 50GHz and offers a top dynamic range. The extremely low phase noise of its local oscillator coupled with cross-correlation even makes it possible to easily 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 phase noise tester 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.

It targets both aerospace and defence and automotive applications, including manufacturers of radar components and synthesisers. Thanks to its additional voltage sources, the tester is also ideal for measuring VCOs in research and development and, thanks to the high measurement speed, also in production.
