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.
5.1.1
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 quanti-
ties and display formats, depending on what you want to learn from the data. A
minimum of two analyzer test ports are required for transmission measurements.
In the following example, the analyzer is set up for a two-port transmission mea-
surement. A frequency sweep range is selected, the instrument is calibrated and
the measurement result is analyzed using various display formats.
5.1.1.1
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
ZNLE to start
from a well-defined instrument state.
