Noise Figure Measurement without a Noise Source on a Vector Network Analyzer

This application note describes the noise figure measurement using the R&S Vector Network Analyzers of the ZVA and ZVT series.  It explains the concept of measuring noise figures without the need for a characterized noise source.  Furthermore, it discusses different measurement applications and the respective setup and implications

Phase noise measurement on pulsed signals using the R&S®FSWP phase noise analyzer

The R&S®FSWP, a new phase noise and VCO tester from Rohde & Schwarz, quickly and easily measures phase noise and AM noise with cross-correlation on CW and pulsed signals. Equipped with the R&S®FSWP-K4 option, the R&S®FSWP automatically determines all pulse parameters (e.g. pulse repetition rate, pulse width) that are relevant. All results are available at…

Testing S-Parameters on Pulsed Radar Power Amplifier Modules

This application note describes testing S-parameters under pulsed conditions with the R&S®ZVA Vector Network Analyzer, and a signal generator with a pulse modulator as a signal source.  A L-band radar pulsed power transistor is used as an example device under test (DUT).  The pulse profile mode of the R&S®ZVA is used to analyze the time-dependent behavior of…

Webinar: Radar signal generation with up to 2 GHz bandwidth for single-channel and multichannel receiver testing

Radar warning receivers and direction finding systems are key components of early warning systems installed on board aircraft, ships or vehicles. Besides the pure analog evaluation of pulsed radar signal envelopes, such systems must also reliably detect complex I/Q-modulated signals of modern radars. Modern radars use large instantaneous bandwidths or frequency agility techniques to quickly…
