How to connect labview program in my computer to an oscilloscope

[ramialsaiad]

Hi

Iam quite new in learning Labview. I did a code for producing a sinus wave in Labview program. I want to send this sinus wave through a coaxial cable to an oscilloscope next to my computer to display the oscillations. When I do the connection between the computer and the oscilloscope I do not get any thing plotted , I just get a line. I included my code file below if you want to see it.

What am I doing wrong?

(Just to mention something: I get oscillations in my oscilloscope when I run a youtube video in my computer).

thank you very much

So one end of the coaxial cable is connected to the oscilloscope input... What's the other end connected to at your computer?

Hi

the other end of the coaxial cable is connected to something called adapter (I do not know the full name of it but it is similar to  this http://www.ebay.com/itm/10PCS-BNC-Female-Jack-to-AV-RCA-Male-Plug-Adapter-Coax-Connector-/1823660601...) ,, then this adapter is connected to the sound output port in my computer ( like when you use a headphone)..

Thank you sir

Your program has no output, it only makes a sine wave on the screen.

Hi

How can I make it send out the sinus waves to the oscilloscope?

Thank you

The sound output functions such as "Play Waveform" are in the functions palette under Programming/Graphics & Sound/Sound/Output.

Use the VIs from the Sound->Output:

For a beginner the Express will be easier to use, so go with it.

Thanks you all

If I want to use the labview program as a generator of sinus waves (like this generator http://www.batronix.com/shop/oscilloscopes/Rigol-DS1054Z.html) ,, I want to generate ultrasonic sound waves (bigger than 20 kHz) .. How can I change the following attached file to make it produces ultrasonic sound waves with frequency of 1 MHz?

The main idea is to use the labview as a generator of ultrasoundwaves and then connect a coaxial cable to the computer and then use these signals like for example to plot them in oscilloscope or power a device ect.

How do you expect to generate a 1Mhz signal from hardware that is rated 20hz-20Khz?

OK sir so I cannot generate 1 MHz sinus wave by using labview in my computer

thank you ,, I did not know that
