To use the matching applet, click and drag the black dot on the chart to the location from which you would like to build your matching network. While the point is selected (it will have a gray square around it), you can add elements to the network by clicking on the buttons in the toolbar at the top of the applet. Change the element values by dragging the endpoints on the chart. While the circuit is selected, the elements and their values will be shown in the table at the bottom of the applet.
New! You can now edit the parameters of the selected item on the chart by using the parameters table.
