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.

INTRODUCTION TO SCALAR
NETWORK MEASUREMENTS
Introduction: Even though scalar
microwave measurements have been
made ever since high frequencies
were discovered, they were not
really addressed, as such, but
INTRODUCTION TO SCALAR rather called power measurements or
NETWORK MEASUREMENTS VSWR measurements, etc. It was not
until modern network analysis with
vector error correction was intro-
duced that the rather obvious term
magnitude or scalar measurements
became more popular.
