Rohde & Schwarz FSWP phase noise analyser and VCO tester

The FSWP phase noise analyser and VCO tester from Rohde & Schwarz enables ultrasensitive and ultrafast phase noise measurements. It also allows users to easily measure pulsed sources and residual phase noise of RF components. The instrument can be upgraded to a signal and spectrum analyser.

The phase noise tester is said to enable users to measure the spectral purity of signal sources such as generators, synthesisers and voltage-controlled oscillators (VCOs) more quickly than with other products. The instrument covers a frequency range up to 50 GHz and offers a good dynamic range. The low phase noise of its local oscillator, coupled with cross-correlation, makes it possible to easily measure signal sources that in the past required complex test set-ups or could not be measured at all.

Due to its fully digital signal processing, the product performs complex measurements at the push of a button and features intuitive touch-screen operation. It can quickly and easily measure the phase noise of pulsed sources, as well as residual phase noise, under pulsed conditions. The device is therefore suitable for aerospace, defence and automotive applications, eg, for manufacturers of radar components and synthesisers. Its additional voltage sources also make the product suited to measuring VCOs in research and development and, due to its high measurement speed, in production.
