instantaneous power

[MAGNETDODI]

Hello,

I want to measure instantaneous power with TDS5032B oscilloscope.

I know that the  instantaneous power can be calculated through formula  

My question is how to make that equtaion in program LabView.

I've tried with trigger model while simulating some sinus signal (which has instantaneous power zero for sinus ) but it doesn't seems to work so far.

Here is my picture of my program.

If anyone has any idea what would be the best approach for acquiring data through that equation?

Thank you for your ideas, and suggestions.

Regards,

Dodi

Hello MAGNETDODI,

you appened to post to the LabWindows/CVI forum board, but since your question relates to LabVIEW you should repost it in the appropriate board in order to have full support from LV users.

When posting, I suggest you state also the version of LV you are using and if base package or full/professional version, so that they can give you the most appropriate help.
