For PMU, there are three modes:
two level pulsing (base and amplitude)
SegArb
FullArb
The FullArb has no measurements; it is sourcing only.
The KPULSE utility is accessing the FullArb to play sine waves, etc.
If you want IV measurements AND doing sine wave, you'd have to build it up from a piece wise segments in a SegArb sequence/waveform.
Check out the pmu-dut-examples project and the pmu-segarb-complete test.
It is using the PMU_SegArb_ExampleFull user module of PMU_examples_ulib.
So long as you observe the rules for sequence defining, you can enter any SegArb that you desire on this.
I suggest you contact your sales office/local applications engineer to get some detail on PMU.
