Generating Multiple Phase Coherent Signals – Aligned in Phase and Time

Rohde & Schwarz signal generators present a compact easy-to-use solution for generating phase coherent signals. Different generator models can be coupled to optimally fit user requirements 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.
