Keysight Technologies Pulsed Carrier Phase Noise Measurements Application Note This application note discusses basic fundamentals for making pulsed carrier phase noise measurements. It assumes the reader is familiar with the basic concepts of phase noise and CW phase noise measurement techniques. Table of Contents 3 Chapter 1 Introduction 4 Chapter 2 Fundamentals of Pulsed Carriers Time Domain Representation Frequency Domain Representation 10 Chapter 3 How Pulse Modulation Affects the SSB Phase Noise of a CW Carrier Convolution of CW Carrier Spectra and Pulsed Waveform Spectra Noise Aliasing With Pulse Modulation Mathematical Equation for a Pulsed RF Carrier Decrease in Carrier Power Decrease in Pulsed Carrier Spectral Power 16 Chapter 4 How Pulsing the Carrier Affects the Phase Detector Measurement Technique System Noise Floor Measurement Offset Range Mixer dc Offset Recommended Hardware Configurations LO AM Noise Suppression Phase Transients Pulsed Carrier Phase Noise PRF Feedthrough Measurements Application Minimum Duty Cycle Summary 2 Chapter 1 Introduction This application note discusses basic fundamentals for making pulsed carrier phase noise measurements. Advances in RF and microwave communication technology have extended system performance to levels previously The assumption is made that the reader is familiar with unattainable. Design emphasis on sensitivity and selectivity the basic concepts of phase noise and CW phase noise have resulted in dramatic improvements in those areas. measurement techniques. However, as factors previously limiting system performance have been overcome, new limitations arise and certain Chapter 2 reviews the fundamentals of pulsed carriers in parameters take on increased importance. One of these the frequency and time domains. The majority of t
