Abstract: Phase noise in electronic devices impacts signal quality — increasing error rates in communications links and degrading the sensitivity of Doppler radar systems. We will cover the fundamental theory and mathematics of phase noise. We will also show how phase noise affects communications systems, including both wideband single and multi-carrier systems as well as narrowband OFDM systems. We will also show how radar affects the sensitivity of Doppler radar systems. Finally, we will cover measurement techniques and solutions for measuring both absolute and residual phase noise as well as discuss some fundamental trade-offs in selecting different measurement architectures.

Bio: Brooks Hanley is a Factory Application Engineer focused on phase noise analysis and high-performance analog signal generation for the Aerospace and Defense and Government Solutions group at Keysight HQ in Santa Rosa, CA. Brooks has worked for Keysight/Agilent for 12 years and previously worked as a Signal Sources Applications Support Engineer and has also interned in the New Product Introduction (NPI) test team and the Signal Analysis firmware team. He earned a BSEE, BS Physics and BA Mathematics from Sonoma State University in 2012. He also holds an MSEE and MBA from California Polytechnic State University. He is currently working on measurement science, technical content development (including giving technical seminars), and working with key customers on their measurement needs in phase noise and high-performance analog signal generation. He is from Sonoma County and attended Technology High School in Rohnert Park, CA.
