Phase-Coherent Signal Analyzers and Generators for MIMO Test and Prototyping

Abstract:

RF signal generators and analyzers have traditionally been single-channel instruments, but applications such as beamforming and phased array direction finding require multichannel, phase-coherent instrumentation. Take a detailed look at the architecture of a 4-channel RF signal analyzer, discuss how you can attain industry-leading channel-to-channel phase coherence, and compare these results to the widespread practice of sharing a common 10 MHz reference to achieve coherency.
