Load-line effect compensation (LLEC) for the PMU

Load-line effect compensation (LLEC) is only performed for standard pulse I-V testing using PMU
measure ranges. It is not performed when using 4225-RPM measure ranges (10 µA). The active
RPM circuitry provides its own analog LLEC (assuming there is a short cable from the RPM to the
DUT).
