                                    The HP Model 8754A Network Analyzer consists of an
internally leveled, 4- to 1300-MHz, swept source. Polar or
rectangular measurements are displayed on a cathode-ray tube
(CRT) through two independent channels. With appropriate
signal-routing accessories, the 8754A is a fully integrated
stimulus/response test system that measures magnitude and
phase characteristics of linear networks by comparing the
incident signal with the signal transmitted by the device
under test or reflected from its input.
1-20. The basic transmission measurements are
insertion loss or gain, insertion phase, and transmission
coefficient (S2i or Si2)· The basic reflection measurements
are return loss, from which SWR can be calculated, and
reflection coefficient (Sjj or S22X from which impedance can
be calculated or read from a Smith chart overlay.

This manual applies directly to instruments whose serial
number prefix is 1914A.
