Diode IV Curve

[Mick790]

Need some help guys, very new to labview and this is my first project using it. I need to get the IV Curve from a Diode. My current method is using myDAQ assistant.

First step in my program: Provide a voltage. Now my voltage range is from 0v to 1v. So I have set a for loop which will allow the daq assistant to provide each voltage (0, 0.1, 0.2...etc.)

Second Step: I have another daq assistant which is setup to read the current.

The problem I have is that everything connects up fine to the xy graph, and when the run button is pressed there are no errors. The only problem is I am not getting anything showing on the graph.

I have attached the program below for you guys to view.

Hello Mick,

I changed your vi. Hopefully it will function now.

You only have to fill in the physical channels yourself. I don't have DAQmx for 2012, so made it in 2011

Cheers! Will give this a go and see how it works.

Thanks for your time.

Unfortunately the MyDAQ will only show the input ports but won't slect the outputs. Tried configuring it and it wont show any output ports to choose from which means every time it tries to run the program it brings up an error.

Aren't you able to fill it in manually?

could you post a screenshot?
