LC Card

The LC card specifies complex, series and parallel circuits applied between connector pins and also between a connector pin and ground.

On the Source/Load tab, in the Loads / networks group, click the  Load icon. From the drop-down list, click the  Load cable (LC) icon.



Figure 1. The LC - Load a cable with a complex impedance dialog.

Parameters:

Define/replace a load at a cable connector
Define/replace a load at a cable connector with the following parameters.
Remove a load at a cable connector
A load can be removed between two connector pins by defining the Connector label and Pin (ground=0).
Remove all cable loads previously defined
All previously defined LC type loads are removed.
Load name
The name of the load.
Define/replace load between
A load can be placed between two connector pins by defining the connector label with the Connector label text box and the pin number with the Pin (ground = 0) text box.
Complex impedance
Define the real and imaginary parts of the complex impedance in Ohm using Real part of impedance (Ohm) and Imaginary part of impedance (Ohm) respectively.
Series circuit
The resistor value in Ohm, inductor value in Henry and the capacitor value in Farad to be added as a series circuit.
Parallel circuit
The resistor value in Ohm, inductor value in Henry and the capacitor value in Farad to be added as a parallel circuit.
SPICE circuit
Specify the name of a one-port SPICE circuit to define a load between two pins. Define the SPICE circuit using the SC card.
Touchstone file
Specify a one-port Touchstone file (.s1p, .z1p, .y1p) to define a load.
Note: If the load is added to a port that has a voltage source, the load is placed in series with the voltage source.
