Pulsed Noise Figure Measurements

Components used in mobile communication and for radar systems often operate under pulsed or bursted conditions. In a wide range of applications, these devices must be characterized in pulsed condition to get valid measurement data as the devices might change their performance when tested in continuous mode. The noise figure, one of the important parameters for low noise amplifiers, can only be determined for continuous operation with conventional test equipment.

This white paper provides information how to perform noise figure measurements under pulsed or bursted conditions with spectrum analyzers and noise sources, and introduce the capabilities of the Rohde & Schwarz FSW signal and spectrum analyzer to perform this measurement.
