impedance conversion...] dialog box will appear.
Tick the [impedance conversion... on/OFF] button in the dialog box to enable the port impedance conversion... function.
Click the [Port selection] drop-down menu and select the port for impedance conversion....
Edit the real part and imaginary part of the impedance to be transformed in the [R (real part of impedance)] an [jX (imaginary part of
impedance)] edit box. Click [OK] to complete the setting.

Four-port Fixture Embedding/De-embedding
Simulate embedding/de-embedding of the four-port fixture to obtain the simulation results of the tested device after
embedding/de-embedding of part of the network.
1) [Four-port fixture embedding/de-embedding] dialog box
a) [Mode selection] drop-down menu
Select the fixture embedding/de-embedding mode. The vector network analyzer is configured with three network models (Mode A, B
and C).
Fig. 7.28 Three Modes of Fixture Embedding/De-embedding
b) [Network embedding/de-embedding type] drop-down menu
The network embedding/de-embedding type is the first item of the drop-down menu of Network 1 (Network 2 is enabled in Mode C).
The drop-down menu includes three options: none, de-embedding and embedding.
c) [Import file] button
Click this button and select the S4P file for import of the fixture S-parameter in the pop-up dialog box (as shown in Fig. 7.25). After the
file is selected, the file name will be display in the box on the right side of the [Import file] button.
d) [Port selection] drop-down menu
The port selection part includes the vector network port and fixture port. The [Fixture port] drop-down menu is not displayed in the
default mode. The selected mode and network embedding/de-embedding type will be displayed in the schematic diagram. Select the
