Rohde & Schwarz: Generating multiple phase coherent signals

October 04, 2016 // By C. Tröster-Schmid, T. Bednorz
Rohde & Schwarz signal generators present a compact way to generate phase-coherent signals. Different generator models are possible in terms of number of phase coherent channels and RF frequency range. This application note explains how to generate phase coherent signals, details what to consider and how to best calibrate the relative phases and timing between the individual channels. This document also presents various measurements of the phase stability over time for different RF frequencies.
