FET curve tracer (not working)

Hello

 

I am currently working on a VI to plot the curves of FET. I have the following attached VI. However when I use the following parameters

 

RG = 10 kΩ and RD = 0.1 kΩ.

VGG start at 1.0 V, stop at 2.0 V and 11 points

VDD start at 0.0 V, stop at +10.0 V, and 41 points.

Delay = 10 (ms).

 

I am not getting the required curves. Can you please help ?

What are the required curves???

 

Of course we don't have your hardware, so we cannot really reproduce. Do you have some simulation VIs instead of the DAQ IO?

 

(It would be more helpful and much easier if you could make your input control values to the desired defaults before saving instead of typing all the values in the message. The ramps only need to be recalculated when the inputs change. Why are there 1ms delays in the ramp generating inner loops??? I would delete these and instead place a small delay in the main loop of the toplevel VI.)

I am trying to make a simulation VI which would work in exchange for the DAQ.

 

Why are there 1ms delays in the ramp generating inner loops??? I would delete these and instead place a small delay in the main loop of the toplevel VI.

 

I know it aint important but I did not mind it being there so did not change it. Can you change the VI as u said and post accordingly. What are the advantages of doin what u said ?

And yeah.. Any idea how do I make such a simulation VI to replace the DAQ ?
