Conclusion: From the results in Figure 5, one can ascertain that using the GHz socket in

the described setup can in fact measure the Kelvin resistance between two points. The

test chip that was daisy chained in this pattern allowed us to see differences between

points because of the length of the trace (more length = more resistance), you can see that

the farther you got away from the first pin, the resistance increases slightly. It was used

expressly for that purpose; a typical MLF chip will also work in this application although

the results will be unique to that chip.
