The following figure shows a current sweep on a resistive load of 200 Ω. For this example, the SMU is
programmed to sweep current to 100 mA, limit voltage (6 V), and limit power (500 mW). When
sweeping, the actual source output varies according to the programmed source value until the voltage
limit is reached. As the figure shows, the output sources the programmed value until placed in voltage
compliance at the 6 V limit. The sweep then continues (programmed current source values increase
along the green sweep points line), but the output remains at the same value as when the SMU went
into voltage compliance. This continues until the programmed source value sweeps to a high enough
level that the power limit line is reached (in this example, 500 mW). At this point, the voltage and the
current start to decrease, lowering the current and voltage values along the DUT load line. When the
last point is swept (100 mA), the actual output is 25 mA (at 5 V).
