Adding a Load

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

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


    Figure 1. The Create load dialog.
  2. 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.
  3. In the Label field, add a unique label for the impedance load.
  4. Click the Create button to create the load and to close the dialog.
