18 Vector Network Analyzer
Available for the R&S FPC1500 with the optional VNA application.
The vector network analyzer (VNA) application provides the functionality to character-
ize networks with one or two ports. The VNA application allows you to determine the
reflection or transmission characteristics of the device under test (DUT). In addition to
the magnitude of the transmitted and reflected power, vector measurements also deter-
mine the phase characteristics of the DUT.
All measurements in the VNA application require a tracking generator that is available
with the R&S FPC1500 (RF output). The tracking generator transmits a reference sig-
nal through the internal VSWR bridge to the test port. The reference signal (or stimulus
signal) is the reference for the result calculation.
Selecting the VNA application
1. Press the "Mode" key to open the mode menu.
2. Select the "Vector Network Analyzer" menu item.

The VNA application provides several measurements for various purposes. For each
measurement, you can also select one of several result formats that show the results
from different perspectives.
