Patent ID: 7518378

Claim:
A method for calibrating a pulse I-V measurement system for testing a DUT having at least two terminals, said system having a first pulse measurement device connectable to an instrument end of a first test conductor; a pulse generator connectable to an instrument end of a second test conductor, said test conductors each having a DUT end connectable to respective DUT terminals; and a second pulse measurement device, said pulse generator being adapted to float on the potential of said second pulse measurement device, said method comprising: shorting the DUT ends of said test conductors together; connecting said pulse generator to said second test conductor; sourcing a first voltage through said test conductors and the load resistance of said first pulse measurement device with said pulse generator; measuring a second voltage across said first pulse measurement device load resistance with said first pulse measurement device; determining the current through the sense resistance of said second pulse measurement device based on said second voltage and said first pulse measurement device load resistance; measuring a third voltage across said sense resistance with said second pulse measurement device; determining the resistance R S of said sense resistance based on the current through said sense resistance and the third voltage; and using R S to correct measurements made on said DUT.
