Viewing the Input Impedance

View the source input impedance (real part and imaginary part) of the transmission line on a Cartesian graph.

1. Create a new Cartesian graph.
   1. On the Home tab, in the Create new display group, click the  Cartesian icon.
2. Add the source input impedance to the Cartesian graph.
   1. On the Home tab, in the Add results group, click the  Source data icon.
3. View the real part of the impedance.
   1. On the result palette, in the Traces panel, select VoltageSource1.
   2. On the Quantity panel, from the drop-down list select Impedance.
   3. On the Quantity panel, click Real.
4. Duplicate the VoltageSource1 trace using one of the following workflows:
   • On the Cartesian context tab, on the Trace tab, in the Manage group, click the  Duplicate trace icon.
   • On the result palette, a right-click context menu is available on the trace. From the drop-down list, select Duplicate trace.
   • Press Ctrl+K to use the keyboard shortcut.
5. View the imaginary part of the impedance.
   1. On the result palette, in the Traces panel, select Vo1tageSource1_1.
   2. On the Quantity panel, click Imaginary.
6. [Optional] Repeat Step 4 and Step 5 to change the legend position and remove the graph footer.
