how to add sweep voltage (start & stop voltage) with some step in Voltage to the VI posted

[frank11]

Hi,

I have a vi attached along with this forum. It is a vi used to measure voltage and current with the help of keithley 2400. I need to make some changes to my vi, like I want to add sweep on voltage (start & stop voltage) with some step voltage. and then plot the graph for v vs i. I know that there is an example vi with sweep voltage. I tried using it but it didnt work. Please help me out.

It looks like the VI does some sort of sweep; otherwise, why bother graphing?

Are you saying this isn't your VI?

Yes it is my vi but I just have the maximum amplitude setup. I also need a start and stop or maximum n minimum voltage setup

Hi,

From what you described you are reading voltage and current, but you want to add a sweep, so are you trying to sweep the voltages you are reading?  I am not sure what example you were working from but here is a link to an example on how to do a sweep:

Thanks for the help.

I am using a keithley 2400 n yes I am calculating voltage and cureent. What I need is i need an option of start and stop voltage so that there is a sweep in voltage and with that I can plot a graph for V-I. So I want to calculate current for each and every point
