How do I setup Labview to do transistor IV characteristic curve

[Al92651]

I am brand new to LabView, could some help me get started on setting Labview to set up a simple IV curve for a transistor.

You will not get a useful answer to this question.  Too unspecific.

How will you set/measure voltages?  How will you measure currents?  FET or bipolar?

LabVIEW is great for controling hardware, but it is not hardware itself.

Thanks for the input. I am making an external measurement. I am using NI Elvis to breadboard the circuit and supply dc voltages. I assume this is the best way to measure beta for a BJT.

Well....beta is defined as a current amplification, so you will have to be clever enough to figure out how to use the ELVIS, which generates and measures voltages, to generate and measure currents.  This is left as a problem for the student...

As for the LabVIEW part:  I would divide this into two tasks:  learning how to deal with loops, program flow, graphing, and other "all inside the computer" tasks, and learning how to read and write voltages with the ELVIS (generally refered to as DAQ).

Here's my recommendation:  fire up LabVIEW, open the help, and start with the "getting started" section.  When you run out of steam there, you can search specific topics on the NI support website (e.g. search "beginner tutorial" in this forum to get lots of suggestions).

Don't try to skip the step where you spend the time to learn the basics of how to do things in LV.  It will just lead to a lot of frustration.

Good luck!
