Performing Measurements
This chapter takes you through a sample session with a R&S
ZND network analyzer
and describes basic operation tasks.
Safety considerations
Before starting any measurement on your network analyzer, please note the instruc-
tions given in
Chapter 3, "Putting the Analyzer into Operation"
Use the "S-Parameter Wizard" accessible via TRACE – [MEAS] > "S-Params" > "S-
Param Wizard..." to measure S-parameters in a straightforward way. The wizard pro-
vides a series of dialogs where you can select the test setup, screen configuration and
measurement parameters, configure the essential channel settings and perform a gui-
ded 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.

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.
