I would like to know where do I find the componente that have the function of an osciloscope in LabVIEW, somebody knows??

what you wanna do ? an oscll measurements?

I ' d like to read voltages and currents, like an osciloscope.

OK you need to code that , is it gonna be from a device ? are u reading from physical channels ?

You really need to learn how to ask correct questions. You will not be penalized for using more than a dozen words. Reading voltages and currents (which a scope does not do), requires some sort of hardware. What do you have? Have you looked at the shipping examples? There are examples that simulate a scope and examples that use an NI DAQ card to acquire a signal. There are examples on the Developer Zone such as this one.

There u go , a VI that measure voltage from osciscope , it is only taken from 1 channel now 🙂

Open the VI , select ur channel (from ur device) , and then run it

kmous, when posting examples please don't disable the Abort button. People sometimes need to use that button. Unless the example is to explicitly provide an example of a window appearance, leave the appearance set to "default".

 

Also, with respect to your (ur) VI:

 

  • That VI does not read from an oscilloscope. You (u) are providing an example that reads from a DAQ card. 
  • There is little point in reading a 2D DBL array, peeling off the first column, making that back into a 2D array, transposing it, and then graphing it (see Rube Goldberg), especially when the example is supposed to be, as you (u) said, for a single channel. You (u) are basically wasting time performing unnecessary operations. Worse, you (u) are providing poor programming techniques to someone who may just be learning about LabVIEW. Setup the VI to actually read a single channel (i.e., make the channel selection be a single channel), and then set the DAQmx read to read a single channel as a 1D array that you (u) can wire directly to the graph indicator.

He said read like osc so i thought he wants a VI that act like an Osc , we will see when he gets back to us 🙂

 Here is another Version that measure 1 channel 1 sample

I need a function that works like an osciloscope INSIDE the LabVIEW, not a function that reads voltages and corrents OF the oscilscope.
