SCALAR NETWORK ANALYSIS: AN ATTRACTIVE AND COSl-EFFECTIVE TECHNIQUE FOR TESTING MICROWAVE COMPONENTS Hugo Vitian Network Measurements Division 1400 Fountain Grove Parkway Santa Rosa, CA 95401 RF ~ Microwave Measurement Symposium and Exhibition Flio- HEWLETT ~~ PACKARD www.HPARCHIVE.com Scalar Network Analysis: an Attractive and Cost-Effective Technique for Testing Microwave Components ABSTRACT Scalar network characterization is an economic alternative to vector network analysis; in particular, in a productive environment where ease-of-use, throughput and low cost are key considerations. However, scalar measurements are not restricted to frequency response measurements on linear networks. Scalar network analyzers are very powerful analysis tools to characterize amplifiers, mixers, modulators, and other components as a function of signal level or control parameter, as well as for cable testing in frequency- and distance-domains. This presentation describes the fundamental measurement concepts and discusses some specific examples.
