NI DCPower 17.0

[GIrmscher]

Hello,

I am trying to set a sequence of current values with the PXIe-4139 while measuring the exact current and voltage values for each step of the sequence.

I do not have any experience with the DCPower driver so far.

Correct me if I´m wrong:

I am able to set the points for the sequence with the niDCPower Set Sequence.vi after initializing with the DCPower Initialize with Channels.vi. Then I have to go into the committed state with the Commit.vi.

For applying the sequence I use Initiate.vi so the sequence is set by the PXIe-4139.

How is it possible (if it is possible) to trigger a measurement of the actual current and voltage for each step of the sequence?

Thanks in advance.

Hi there,

did you have a look at the examples delivered with LabVIEW? There is an example NI-DCPower: Advanced Sequence Changing Output Function.vi which does pretty much what you try to accomplish as far as I understand.

It is not triggered, but you can combine it with one. You need the Sequence Advanced Trigger. 

Hope I could help you
