1. Connect the DUT between test ports 1 and 2 of the network analyzer as shown
above.
2. Use the [Preset] key to restore a well-defined instrument state.
The analyzer is now set to its default state. The default measured quantity is the
transmission S-parameter S
21
.
Select [Trace] and use the control elements in the "Traces" softtool tab if you wish to
create additional traces and diagrams.
Selecting the sweep range and other parameters
After a system preset the display shows a diagram with a dB magnitude scale, and the
S-parameter S
21
is selected as a measured quantity. This S-parameter is the forward
transmission coefficient of the DUT. It is defined as the ratio of the transmitted wave at
the DUT's output port (port no. 2) to the incident wave at the DUT's input port (port no.
1).
The R&S
ZNL/ZNLE automatically adjusts its internal source and receiver to the
selected measured quantities: For an S
21
measurement, a stimulus signal (termed a
1
)
is transmitted at the analyzer port no. 1; the transmitted wave (termed b
2
) is measured
at port 2. The stimulus signal from the analyzer port no. 2 is not needed except for
some calibration types.
