Prerequisite
The instrument is set up, connected to the mains system, and started up as described
in
Chapter 4.1, "Preparing for use"
Use the "S-Parameter Wizard" accessible via [Meas] > "S-Params" > "S-Param Wiz-
ard..." to measure S-parameters in a straightforward way. The wizard provides a series
of dialogs where you can select the test setup, screen configuration and measurement
parameters, configure the essential channel settings and perform a guided calibration.
Measurement stages in the wizard
The individual dialogs of the "S-Parameter Wizard" correspond to the typical stages of
any measurement:
1. Select the test setup.
2. Define port impedances.
3. Select the measurement parameters and the diagrams.
4. Define the sweep range.
5. Adjust the receiver and source settings (measurement bandwidth, source power).
6. Perform a calibration.
4.3.1.1
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.
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
ZNL/ZNLE to start from a well-
defined instrument state.
