GENERAL DESCRIPTION The Model 37XXXC Vector Network Analyzer System measures the
magnitude and phase characteristics of networks: amplifiers,
attenuators, and antennas. It compares the incident signal that leaves
the analyzer with either the signal that is transmitted through the
test device or the signal that is reflected from its input. Figures 3-1
and 3-2 illustrate the types of measurements that the 37XXXC can
make.
