fixed voltage, x axis time, y axis current(or Resistance)

Hi, I'd like to ask for help with Labview.

I'm using keithley 2450 and USB-GPIB.


The functions I want to implement are as follows. Fixed voltage values (voltage can be set as desired), time on the x-axis (start from 0 seconds, end from set time or number of data) Current (or resistance) on the y-axis. I want to store 1. time (data corresponding to the y-axis) and 2. current values (or resistance) in Excel at the end of each reading function (i.e., at the end of each loop).

If I press Start, I want to set the name of the file that will be saved to Excel, and if I press Stop, I want to save only the values for the loop right before. If you press Start again, I hope to make sure that I can save it as a new file again.

The functions above are difficult for beginners to implement? How many days will it take..?

The file I attached is Single read. I looked up other information and found that it can be implemented to some extent if I modify the attached file and loop.

But I'm such a beginner that it's very difficult to study. 😞
Any information is fine, so I'd appreciate it if you could give me some helpful advice. Thank you for reading...

As you are a "such a beginner" I suggest you to take the "Training resources" as offered in the header of the LabVIEW board.

Basically the same suggestion as I already gave you yesterday!

Once you proceed with those "Training resources" it will be easy to implement all that stuff.

Hint: Basically you can use a state machine approach to execute one step after the other…
