Theory of Operation

Information in This Chapter

This chapter provides a general description of the operating theory of the
N5227A 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
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
you read the information in this chapter.
