Extracting quantities, such as the propagation factor or the characteristic impedance of a transmission line based on measured S-parameters, can be more involved than expected. Experience teaches that even if the S-parameter measurements look smooth

We develop an empirical model for the warm-up drift in a harmonic phase standard used to calibrate the phase distortion of a nonlinear vector network analyzer. The model enables us to estimate the time at which the standard reaches stability

A low-cost, inductive current probe designed for integration into a disk drive trace suspension assembly is described. The main consideration for this design was to use the same materials currently found in trace suspension assemblies, and thus reduc

Conference, 2003. Fall 2003. 62nd ARFTG Microwave Measurements.
In this paper, we present the first published repeatability study of commercial harmonic phase standards (HPS) measured by a nonlinear vector network analyzer. Specifically, we measure two harmonic phase standards, one of which is specified to 20 GHz
