hysteresis loop

[francescof4]

Hello to all
I need to create a look hysteresis loop such as that in the attached figure.
I can do the first part but not the second or third.
Suggestions?

Hi Francesco,

does your "loop" consist of 3 arrows? 🙂

Anyway: use "Signal Generation" functions to create the signals you need (your image makes me think you want 3 ramps) and append them…

Hi Gerd.

thank you for your support

I dont need create a signal just a sequence of values that could be 0,1,2,3,4,3,2,1,0,-1,-2,-3,-4,-3,-2,-1,0

So i need to give to my instrument a single value of voltage

I've attached my vi for more semplicity

Well, from yur own description you want to create an array of values, consisting of 3 ramps: 0 to +4, then +4 to -4, then -4 to 0.

Signal generation functions will be a great help for you!

Yes, you want to send scalar values to your device.

Ever heard of "autoindexing at loop borders"?

Your array of "hysteresis loop" values will be autoindexed to scalar values in the loop…
