If you wish to define the added network by an imported set of 2-port S-parameters, select the
2-Port
transformation network, click
Read Data From File,
and load the parameters from a 2-port (*.s2p)
Touchstone file
.
If you wish to define the added network by an equivalent circuit, select the circuit type and adjust the
parameters R, C, and L displayed in the right half of the dialog.
Click
Embed DUT
and
Close
the dialog.
The traces of the active channel show the characteristics of the DUT including the virtual transformation
network inserted between port 1 of the analyzer and the DUT.
To remove a real transformation network from a port...
Suppose that your 2-port DUT has a real, known 2-port transformation network at port 1.
Connect the DUT (including the transformation network) between test ports 1 and 2 of the analyzer so
that the transformation network is placed between port 1 of the analyzer and the DUT.
Establish the necessary
Channel
settings (port configuration, sweep range and type etc.) and select
the measured quantities
(Trace – Measure).
Click Channel – Cal – Port Extension – Deembedding to open the Deembedding... dialog.
In the dialog, select the
Port
connected to the physical transformation network (e.g.
Port 1)
and do one
of the following:
If your transformation network is described by an imported set of 2-port S-parameters, select the
2-
Port
transformation network, click
Read Data From File,
and load the data from a 2-port (*.s2p)
Touchstone file
.
If your transformation network can be described by an equivalent circuit, select the circuit type and
adjust the parameters R, C, and L displayed in the right half of the dialog.
Click
Deembed DUT
and
Close
the dialog.
The traces of the active channel show the characteristics of the DUT without the effects of the removed
physical transformation network.
