Listing Load Impedances

Analyzing how power is dissipated or transferred through lumped loads (such as resistors, inductors, or capacitors) is vital for understanding matching networks or loaded antenna performance. Use the following steps to tabulate and plot these values:

1. Select the Loaded Wire: Right-click on the wire where you have placed a load to open the pop-up menu.
2. Open the “List Currents” Toolbar: Select the List Currents command (Fig. 1).
3. Navigate to the Load: Use the slider to move to the specific segment containing the load.
4. Access the Load List: Click the Load List button (this button remains disabled unless a load is detected on the selected segment).

Data Interpretation and Plotting

The Load List dialog box provides a detailed breakdown of the following parameters across your frequency range:

• Load Current and Voltage: The actual values present at the load’s terminals.
• Power: The real and reactive power consumed by the load.
• Impedance: The calculated impedance of the load at each frequency step.

To visualize this data, select the desired parameter from the menu in the upper-right corner and click the Plot button to open the AN-XY Chart.
