Theory of Operation
Information in This Chapter
This chapter provides a general description of the operating theory of the
N5227B 2-port and 4-port PNA microwave network analyzers.
— Theory of operation is explained to the assembly level only.
— Component-level circuit theory is not provided.
— Simplified block diagrams are included for each functional group. More
detailed block diagrams are located at the end of
Chapter Five at-a-Glance
Although simplified block diagrams are included within the description of
each functional group, it is recommended that the more detailed block
diagrams, located at the end of
, be available for reference, as
you read the information in this chapter.
