The Ground Loop (De-)Embedding dialogs contain the following control elements:
 (De-)embed DUT enables or disables the (de-)embedding function.
 Transformation Network contains all available ground loop networks (see below). Networks are
defined either by means of imported S-parameter data or by lumped elements. The active network
appears in inverse colors. The element parameters (C, R, L) for the selected network are
displayed on the right side.
 Read Data From File... is enabled as long as the 1-Port Data network is active. This network is
defined by its S-parameters stored in a one-port Touchstone file (*.s1p). No additional parameters
are required.
 Set to Ideal Ground is enabled as long as the 1-Port Data network is active. An imported S-
parameter set is replaced by the S-parameters of an ideal through connection, which eliminates
the transformation network.
Circuit models for ground loops
The first ground loop network is defined by its S-parameters stored in an imported one-port Touchstone
file (*.s1p). No additional parameters are required.
The alternative networks are defined by an inductor L connected in series with a resistor (Shunt L), and by
a capacitor C connected in parallel with a resistor (Serial C). In the default setting the resistors are not
effective, since the serial Rs are set to 0 Ω, the shunt Rs are set to 10 MΩ.
