-SCS Pulse Card (PGU and PMU) User's Manual Section 3:
Setting up PMUs and PGUs in Clarius
4200A-PMU-900-01 Rev. B March 2023 3-45
The following figure shows a family of curves from a fairly high-powered device with the
load-line effect.
The following figure shows the same device tested with load-line effect compensation enabled. With
LLEC enabled, the curves stop at the programmed V
d
= 12 V. Note that the top curve, in the red circle,
did not reach the 12 V setting. This is because the PMU 40 V source range reached source
compliance. In this case, the PMU is at its limit and cannot source any more voltage or current to this
particular resistance. See the 4200A-SCS Parameter Analyzer Datasheet for more information on the
PMU maximum source power versus device resistance. You can access the datasheet from the
Learning Center.
