Cmn
ZConversion
*1
Displays softkeys for setting up the common impedance conversion function. When the reference impedance of
two unbalanced ports is expressed as Z
0
, an automatic conversion sets the differential mode reference impedance
of the converted balanced port to 2Z
0
and the common mode reference impedance to Z
0
/2. Common impedance
conversion is a function that further converts Z
0
/2 into another reference impedance.
Cmn
ZConversion
Enables or disables the common impedance conversion function.

De-Embedding S4P Displays the softkey to make the setting of the 4-port network embedding/de-embedding feature. The 4-port
network embedding/de-embedding feature is the feature to embed or de-embed your desired network that you have
defined in a 4-port touchstone data file.
De-Embedding
S4P
Toggles ON/OFF the 4-port network embedding/de-embedding feature.
