Extending the Calibration Plane Using Network
De-embedding
Network de-embedding is a function for performing measurements, test port by test port,
by removing the characteristics of an arbitrary network defined by a Touchstone data file.
By removing the characteristics of the cable, test fixtures, etc. between the actual
calibration plane and the DUT, the calibration plane can be correspondingly extended. The
network de-embedding function can be used together with the port extension function (see
Figure 7-2).

Using the Network De-embedding Function
Step 1.
Prepare a two-port Touchstone data file (.s2p format) corresponding to the network to be
removed.
Step 2.
Press
-
Fixture Simulator
-
De-Embedding
.
Step 3.
Press
Select Port
.
Step 4.
Press
1
,
2
,
3
, or
4
to select the test port from which the network de-embedding is
performed.
Step 5.
Press
User File
.
Step 6.
Using the dialog box that appears, select the Touchstone data file defining the
characteristics of the network to be removed. Once the file is selected, the selection of
Select Type
automatically changes to
User
. To cancel a user-defined file that has been set
up, press
Select Type - None
.
Step 7.
Repeat Step 3 to Step 6 to set up the Touchstone data file for each port from which a
network is to be removed.
Step 8.
Press
De-Embedding
to turn the network de-embedding function
ON
.
Step 9.
Press
Return
.
Step 10.
If
