Patent abstract
A method for determining the phase characteristics of a nonlinear analog device includes application of a test signal, which may be linear-FM, to the nonlinear device. The converted signal is digitized and mathematically converted to baseband in ideal fashion. A digitized version of the original test signal and the downconverted signal are phase compared to determine the phase error.
