6 Performing measurements
This chapter takes you through a sample session with a R&S ZNA network analyzer
and describes basic operation tasks.
Prerequisite
The instrument is set up, connected to the mains system, and started up as described
in Chapter 3, "Preparing for use", on page 13.
6.1 Transmission S-parameter measurement
In a transmission measurement, the analyzer transmits a stimulus signal to the input
port of the device under test (DUT) and measures the transmitted wave at the DUT's
output port. The trace settings allow you to select the measured quantities and display
formats, depending on what you want to learn from the data. A minimum of two ana-
lyzer test ports are required for transmission measurements.
In the following example, the analyzer is set up for a two-port transmission measure-
ment. A frequency sweep range is selected, the instrument is calibrated and the mea-
surement result is analyzed using various display formats.
6.1.1 Connecting the instrument for transmission measurements
To prepare a transmission measurement, you have to connect your DUT (which for
simplicity we assume to have appropriate connectors) in-between a pair of analyzer
test ports. It is recommended that you preset the R&S ZNA to start from a well-defined
instrument state.
