Pin Current | ![]() |
A pin current source is applied at the end of a conductor and is used to create a driving current of a specified waveform type and amplitude.
Prior to defining a Pin Current Source, the cabling within the segment to be excited should be completed.
Click Pin Excitation within the Excitation section under the MHARNESS tab in the Ribbon. Then select
Pin Current from the drop-down menu.
Alternatively, right click Sources in the Simulation Tree and select Pin Current.
In the top left of the model window, the pin current tools will appear.
Using the Select Line tool, select the line at the end of which the pin current will be placed. Hovering above the line will highlight it. The color of the line will not change when selected.
Using the Select Point tool, select the termination point at which the pin current will be placed. Hovering above the point will highlight both it and the previously-selected line. Termination points not connected to the previously-selected segment will not be selectable.
A new window containing the cable cross section will appear.
Select the cable to which the pin current should be assigned. It will glow orange once selected. Users may need to use the drop-down menu at the top of the cross section window to change between cable layers. (layer 1 indicates the outermost cable(s) while the highest layer # indicates the innermost cable(s)). Users can also select Show Labels to see the cable names. Once selected, click OK to complete the pin current source setup.
The excited termination point will be recolored neon green in the model window. Users may need to hide the junction point labels to see the pin current source.
The pin current source will be added to the Simulation Tree under the Sources node as Pin Current. The yellow warning label attached to it indicates that the source needs a signal attached to it.
Instructions on adding signals can be found here. Once a signal is attached to the source, the yellow warning label will disappear.
Adjust the definitions of the Pin Current Source at any time by right clicking it within the Simulation Tree and selecting Edit from the pop-up menu.
