VECTOR MEASUREMENTS BY A DIGITAL OSCILLOSCOPE

C. Narduzzi, A. Trivero
Abstract:
Vector measurement, that is, the determination of the magnitude and phase of a complex quantity, is usually associated with rather sophisticated measurement equipment. The paper shows that a straightforward and cost-effective implementation can be based on a two-channel digital oscilloscope, which acquires data for a simple signal processing algorithm. An analysis of measurement uncertainty indicates that the main limit of the approach is given by the signal-tonoise ratio in the two measurement channels. Experimental results from an application in the telecommunications field are presented.
