Run an AC Frequency Sweep test of your circuit from the Test Panel. Set the start and stop frequencies to 1GHz and 10GHz, respectively. Choose a "Linear" interval and set the step size to 10MHz. Click the "Preset Graph Plots" button of the test panel to open the Edit Plot List dialog. In the complex signal settings section, choose the "Magnitude/Phase (Degrees)" format and then select the node voltage magnitudes V(2) and V(3) at the input and output ports of the T-Line. Run the AC test. The output graph will show two overlapping constant voltages over the entire 1-10 GHz frequency range as expected.
The program usually plots the graphs with reasonable axis scales and other suitable plot settings. Oftentimes, you may want to change the default graph settings. For example, in the case of the V(2) and V(3) plots, they are identical and constant, i.e. they have the same minimum and maximum left axis limits. To better view this graph, while the graph window is active, click the Edit Axes tab of the Toolbox. From the top Axis drop-down list, select the "Left Axis". Remove the check mark from the "Auto" checkbox and enter values 0 and 1 in the Min and Max boxes, respectively. Make sure to click the button labeled "Apply Above Changes". Also, the AC sweep results are usually plotted on a horizontal axis (X-Axis) with a logarithmic scale. In the same Edit Axes tab, select the "Bottom Axis" from the Axis drop-down list and remove the check mark from "Logarithmic" checkbox.
