“Modern Methods for Absolute & Residual Phase Noise Tests on CW and Pulsed Signals”
Rohde & Schwarz GmbH & Co. KG
Low phase noise is a prerequisite for range and velocity resolution of modern radar systems. Accurate measurements of phase noise and AM noise of synthesizers, high end oscillators (OCXOs, DROs, …), VCOs and components is needed to improve the performance of these systems. A new measurement technique will be introduced, that provides state of the art measurement sensitivity, speed and flexibility for absolute phase noise as well as for residual/additive phase noise measurement on cw and pulsed signals released in the new phase noise and VCO tester R&S FSWP. In addition, extension to frequencies >50 GHz up to 500 GHz is presented and transient measurements (frequency/phase over time) are shown for characterization of settling effects of PLLs and VCOs or frequency agile RADAR systems.
Dr. Wolfgang Wendler studied physics at the University of Bayreuth and did his PhD thesis in 1996 on nuclear magnetic properties of Pt and Al. He joined Rohde & Schwarz in 2004 as product manager for signal and spectrum analyzers. Prior to joining R&S, he worked as development engineer for wireless communication transceiver chips at Temic Semiconductor GmbH in Heilbronn and as process engineer at Loewe Opta GmbH.
