RF Vector Network Analyzer
N9923AN
Analyzer System Operation
The N9923AN RF vector network analyzer operates as either a 1-port or 2-port network
analyzer (NA). One port measurements are made using PORT 1 and two port
measurements are made using both PORT 1 and PORT 2.
The NA function of the analyzer also supports cable and antenna test (CAT) functions.
See
Figure 5-1
for a simplified block diagram of the overall RF analyzer system.
All N9923AN RF vector network analyzers have the same hardware. Options to increase
functionality are enabled via licenses, additional hardware is not required.
Functional Groups of the Analyzer
The operation of the analyzer can be separated into two major functional groups. Each
group consists of assemblies that perform distinct functions. Some of the assemblies are
related to more than one group, and both groups, to some extent, are interrelated and
affect each other's performance.
The major functional groups are:
•
Front Panel Group
•
Measurement Group
Front Panel Group
The front panel group consists of the following:
