PNA Series Microwave Network Analyzers Theory of Operation
N5230A Network Analyzer System Operation
Receiver Group
The receiver converts the test and reference signals to 7.66 MHz intermediate frequency
(IF) signals for signal processing, retaining both magnitude and phase characteristics. The
IF signals are converted to digital information by the digital processing group.
Refer to “Receiver Group Operation” on page 5-19 .
Digital Processor and Digital Control Group
The digital processor and digital control group are divided into a front panel group and a
data acquisition and processing group. The front panel group provides communication to
the network analyzer. The data acquisition and processing group provides the output to
the display, in addition to signal processing and analyzer control.
Refer to “Digital Processing and Digital Control Group Operation” on page 5-21 .
Power Supply Group
The power supply functional group provides power for the other assemblies in the
instrument.
