Key Facts Simple test setup Until now, measuring the phase noise of pulsed sources such as used in radar applications required extremely costly and complex systems. Accurate pulse parameter information and a great deal of patience were needed to achieve stable measurements. When equipped with the R&S®FSWP-K4 option, the R&S®FSWP carries out these measurements at the push of a button. The R&S®FSWP records the signal and calculates all pulse parameters. It then demodulates the signal and displays the phase noise and amplitude noise. Stable measurements take almost no time. All results are available at the push of a button, enabling users to focus on optimizing their circuit design. High sensitivity despite desensitization The R&S®FSWP offers cross?correlation for pulsed source measurements as well. Cross-correlation compensates for desensitization caused by lower average signal power due to longer pulse off times. This enables the R&S®FSWP to achieve a large dynamic range even for phase noise measurements on pulsed signals. Automatic pulse parameter measurement Similar to a dedicated pulse measurement application (R&S®FSW-K6/R&S®FSWP-K6), the R&S®FSWP with R&S®FSW-K4 automatically determines all pulse parameters (e.g. pulse repetition rate, pulse width) that are relevant to measuring the phase noise of pulsed sources. Users do not have to worry about correctly setting these parameters. However, they can define a gate, for example to suppress transients. It is no longer necessary to carry out subsequent corrections, shift the trace or manually limit the available offset range.
