ABSTRACT:
A novel method is described that enables the measurement of the phase of the spectral components generated by an harmonic phase reference generator without using a calibrated sampling oscilloscope. First one uses a vector network analyzer to measure the output reflection coefficient of an harmonic phase transfer standard and of the harmonic phase reference generator that needs to be characterized. Next one connects the transfer standard to a microwave receiver and one measures the spectral components that are generated by the transfer standard. One then connects the harmonic phase reference generator to be characterized to the microwave receiver. The spectral components of the harmonic phase reference generator to be characterized are calculated by using the spectrum of the transfer standard as measured by the receiver, the spectrum of the harmonic phase reference generator to be characterized as measured by the receiver and the known spectrum of the transfer standard.
