Ambisonics depends very much on the phase coherence between the channels -- you need to get the same out when you decode it as you put in when you encoded it.
Especially when using the CW version, the combination of R&S SGS100A and R&S SGU100A is optimal for multitone applications requiring phase coherence.
Our measurements give the most definitive spectroscopic evidence that the material we studied is a superconductor, even above the transition temperature, but one without the quantum phase coherence required for current to flow with no resistance," said physicist Seamus Davis of the US Department of Energy's (DOE) Brookhaven National Laboratory and Cornell University, who led the research team.
