Cross-correlating two receiver chains to allow resolution of coherent noise components is a well-known approach in the world of phase noise measurement. In noise figure (including the differential case), this approach has the potential to reduce the contributions of the ‘instrument noise receiver’ by mitigating the impact of incoherent signals in the two paths. For single-ended noise measurement, such a treatment might lead to a reduction in the level of data jitter for a given acquisition parameter set and macroscopic noise characteristics. This talk will explore some of the possible levels of improvement, potential limiting factors, and example implementation approaches.
