Hi,
I have a project to make an oscilloscope using labview.
Ive connected a function generator and sweep function generator to an xy graph.
I can play with it through frequency and amplitude.
The problem is: how do I make a control for TIME per Division and an another control for Voltage per division.
Help please!

I would probably use a knob control. Change the representation to a I32. Handle the changing of the values with an event structure.

Can you please explain to me how to do that coz Im a beginner (I know about the knob control) ?
I know that I need some calculations for it to work.

You need to manipulate the X and Y scaling minimum and maximum properties using the knobs. Quick example (i forgot the autoscaling property which should be turned off for both).

Hi
I want to design an oscilloscope with data acquisition card usb-6008 and I don't know how to connect daq and equipments. I need to design like above sample but with daq. I don't have enough time. i need help.
sincerely

You are more likely to get good help if you ask specific questions.
Look at the DAQ examples. Some of those may be quite similar to an oscilloscope.
You can replace the function generator VI in the snippet posted by BillMe with the DAQ read VI. You might also need to couple the scale knobs to the amplitude range and timing for the DAQ device. That gets significantly more complicated becaues you will need to stop the DAQ task, reconfigure the task, and start it again.

I guess the wrench looks like a key, depending on how you look at it. 😄
