[[File:b2TUT2_7.png|thumb|350px|Transient Test Setup Dialog]]
In the Toolbox on the left side panel, click on the "'''[[Tests]]'''" tab. Select the "'''Transient'''" option by checking the leftmost check box in the "basic" column. Then, click the "'''Setup'''" button in the Transient test row to open the test settings dialog as shown in the figure below. Set the Start Time to 0, Stop Time to 5m, Linearize Step to 1u and Step ceiling to 1u. Make sure that the '''Single Test''' tab is selected and the check box labeled "'''Graph'''" is checked in the "Output Results Options" section of the dialog.

Before running the test, you have to instruct B2.Spice what you want to plot at the end of the test. Click the button labeled "'''Preset Graph Plots...'''". A new dialog opens up, which looks like the figure shown above. Select the signals v(1) and v(2) and click the button labeled "'''Add->'''" to move them to the graph table. Click the "Run Test" [[File:b2RunTest_Tool.png]] button of this dialog, or use the keyboard shortcut "'''Ctrl+B'''" to run the transient test. The following figure shows up at the bottom of the Workshop.

Since the period of the input pulse waveform is 1ms, your specified time interval contains 5 periods. Both the source signal and output voltage signal are plotted on the same graph. The signal overshoot at the rise and fall of the pulse train are better visible here. In order to examine this transient behavior in more detail, change the transient test [[parameters]] as follows:
Run the transient test once again and examine the new graph that replace the previous one. The transient behavior of the circuit in the first 10 microsecond is clearly visible now. You can further zoom in on that part of the graph. Make the graph view active and open the "'''Edit Axes'''" tab of the '''Toolbox'''.
