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
• Noise Measurement Group (Option 029)
• Digital Processor and Digital Control Group
• Power Supply Group
