Abstract :
We describe a post-processing technique that extends the effective measurement bandwidth of narrowband vector receivers by phase aligning overlapping measurements. We study the repeatability of the method and the propagation of errors as increasing numbers of bands are stitched together. The method can be used to find phase errors both in the excitation band of frequencies, as well as in distortion products, for periodic multisine signals.
