Electrical stress testing discussed herein is the act of varying the DC voltage supplied to the logic unit under test. By using the combination of hardware and software described below, the output voltages of a product's own power supply are controlled remotely and accurately for use in the electrical stress test of the product's logic unit. (Image Omitted) Fig. 1 shows the normal connections between the power supply and the logic unit. There are DC power connections (voltage and ground) and sense lines (voltage sense and ground sense). The power supply's regulation circuitry uses the sense lines to control the output voltage. Fig. 2 shows the connections required to accurately control the output voltage of the product power supply.
