Hello I am currently stuck up while implementing the diode characteristics using LabVIEW . I have tried ample ways to get the diode curve but my efforts are in vain. I am sincerely looking for help from you guys over here. I have attached two .vi The diode with linear curve.vi is one in which i have achieved a linear increase of current with small increase in voltage.The second diode ideal.vi is on in which after used ideal conditions of conducting and non conducting state. The readings are achived using my first year journal. I am very new to the software and would appreciate any help. i have Labview v8.5 n v10. Thanks 🙂

The inner loop stops at 0.7 only if you get lucky. Add indicators connected to the 0.7 constant and to the V(t) line inside the loop. Set the display format on both inidcators to 18 significant digits and uncheck Hide trailing zeros. Turn on execution highlighting to slow things down. Set Vmin to zero and dV to 0.05 and watch it. See the image below. Look at this example for a somewhat simpler approach (and one which uses a more realistic diode model). I put comments on the block diagram to explain the differences from your VI. Lynn

Sir

I had been in contact with Mr. Lynn regarding Labview some months ago and so wanted his help further. Hence I posted it here. I know the rules and understand them too. I wont repeat it again. Sorry
