Abstract
An exemplary implementation of the present disclosure is a power sourcing equipment (PSE) for determining a resistance of a powered cable. The PSE includes a first supply voltage to cause a first current to flow through first and second output terminals of the PSE. The PSE also includes a second supply voltage to cause a second current to flow through third and fourth output terminals of the PSE. The PSE further includes a current modulation circuit offsetting the second current from the first current to create an offset voltage between the second and the first supply voltages to determine the resistance of the powered cable. The current modulation circuit can offset the second current from the first current utilizing a variable resistance switch to adjust the second current.
