Introduction
Theory of Operation provides a general description of the system, and operating
theory of the network analyzer functional groups. Operation is explained to the
assembly level only: component-level circuit theory is not provided. Simplified
block diagrams illustrate the operation of each functional group. An overall
block diagram is provided at the end of the section.
System Operation
The HP 8719D/20D/22D microwave network analyzers integrate a synthesized
source, signal separation devices, a three-channel receiver for measurement of
test device characteristics, and a large-screen display. Figure 12-1 is a simplified
block diagram of the network analyzer system.
