Adding a Load

Apply an impedance load to a wire port, microstrip port, FEM line port, a general network or an ideal transmission line.

On the Source/Load tab, in the Loads/networks group, click the Add load icon.

Figure 1. The Create load dialog.
Under the Load Type drop-down list, specify one of the following:
- Complex impedance
  - In the Real part field, specify the real part of the complex impedance in Ohm.
  - In the Imaginary part field, specify the imaginary part of the complex impedance in Ohm.
- Series circuit
  - To specify a resistor, select the Resistor check box and in the Resistor (Ohm) field, enter a value in Ohm.
  - To specify an inductor, select the Inductor check box and in the Inductor (H) field, enter a value in Henry.
  - To specify a capacitor, select the Capacitor check box and in the Capacitor (F) field, enter a value in Farad.
  Note: If no option is selected, the result is a short circuit.
- Parallel circuit
  - To specify a resistor, select the Resistor check box and in the Resistor (Ohm) field, enter a value in Ohm.
  - To specify an inductor, select the Inductor check box and in the Inductor (H) field, enter a value in Henry.
  - To specify a capacitor, select the Capacitor check box and in the Capacitor (F) field, enter a value in Farad.
  Note: If no option is selected, the result is an open circuit.
- SPICE circuit
  - In the Filename field, browse for a one-port SPICE circuit file to define a load between two pins.
- Touchstone file
  - In the Filename field, browse for a one-port Touchstone file (.s1p, .z1p, .y1p).
    Note: If the load is added to a port that has a voltage source, the load is placed in series with the voltage source.
In the Label field, add a unique label for the impedance load.
Click the Create button to create the load and to close the dialog.
