Testing multi-antenna systems such as phased array or beamforming antennas requires a test system capable of providing multiple signals with constant phase relationships between them. The coherent ...

Physicists have identified a new superfluid phase in a class of quantum systems that, until recently, looked too unstable and ...

Quantum phase transitions describe abrupt changes in the ground state of a quantum system at absolute zero when a control parameter is varied. They are distinguished from classical phase transitions ...

Today, many wireless communications systems incorporate multiple input, multiple output (MIMO) antenna schemes to take advantage of the multipath signal propagation. In addition, many of today’s ...

This application note explains how to generate phase coherent signals, what to consider and how to best calibrate the relative phases and timing between the individual channels. Rohde & Schwarz signal ...
