Functional Groups of the Network Analyzer

The operation of the network analyzer can be separated into major functional groups. Each group consists of
assemblies that perform a distinct function in the instrument. Some of the assemblies are related to more
than one group, and all of the groups, to some extent, are interrelated and affect each other's performance.
The major functional groups are:
• Synthesized Source Group
• Signal Separation Group
• Receiver Group
• Digital Processor and Digital Control Group
• Power Supply Group
