Testing system for detecting a fault and a location of the fault

A testing system for detecting a location of a fault, the testing system comprising:

• a printed circuit board including at least one electric component and at least two nodes, the at least one electric component and the at least two nodes mounted on the printed circuit board, and an electric trace electrically coupling the at least two nodes, and wherein the at least one electric component electrically coupled to the electric trace, each of the at least two nodes including a signal output, a ground output and a location output;
• a testing apparatus including a signal input, a ground input and a location input configured to engage a corresponding signal input, ground input and location output of the at least two nodes;
• and
• a controller electrically coupled to the testing apparatus, the controller configured to receive a test signal from the signal input, a reference ground from the ground input and a location from the location input, wherein the controller is further configured to process a signal from the location output and a signal received by the signal input to determine a fault and a location, wherein the controller provides the location of the node in which the fault is detected.

A method of testing a device, the device including a printed circuit board including an electric trace and a plurality of electronic components, the method comprising:

• providing at least two nodes on the electric trace, wherein each of the at least two nodes includes a signal output, a ground output and a location output;
• providing a testing apparatus including a signal input, a ground input and a location input;
• and
• receiving at a controller a test return signal from the signal input, a reference ground from the ground input and a location from the location input, wherein the controller is configured to provide a location of the at least two nodes in which a signal received by the signal input is a fault.
