How to connect labview program in my computer to an oscilloscope

[GerdW]

Hi ramialsaiad,

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

You can generate such sine waveforms with LabVIEW.

But you cannot output them without hardware capable of such frequencies…

Do you have such hardware?

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

Just to be clear LabVIEW is not the issue here, your hardware is.

A PC soundcard is limited to audio frequencies (20Hz-20Khz), +/- a few percent. 

You just need better hardware.

Hi

my pc is a DELL and it should not manage to generate more than 20 kHz as Mr RTSLVU mentioned

Thank you 🙂

Hi

I understand what you meant , so I guess I need to use a real generator like this : http://www.batronix.com/shop/oscilloscopes/Rigol-DS1054Z.html to generate ultrasonic waves instead of using the labview

Is there any hardware can generate the 1 MHz ultrasonic waves?

thank you

What you need is a Function Generator.  Here are some options for you to look at:

NI PCI Waveform Generators

Tektronix 3390 Arbitrary Waveform Generator

Keysight 33509B Waveform Generator

NI VirtualBench

Personally, I would go with one of the VirtualBench options since it also has an oscilloscope, power supply, DIO, DMM, and Logic Analyzer.

Hi

I have something called "national instruments hi speed usb carrier" http://sine.ni.com/nips/cds/view/p/lang/sv/nid/204178 and another thing called "national instruments ni cdaq 9172" similar to this http://www.ni.com/sv-se/support/model.cdaq-9174.html

Can I use them to generate 1 MHz instead of the things you mentioned above?

Thanks

Both of those are just chassis.  They need a module in order to do anything.  And I am not seeing any C Series modules that can output a signal above 51.2kHz (Niquist states the highest bandwidth signal you can output is ~25kHz).  So that will not work for you.

These two products are only chassis. You need to put a module in them to be able to use them. They are like an "empty DVD case", you need a "DVD disk" too 🙂

Hi

I have cDAQ-9172 here is a picture : https://www.google.se/search?q=c+series+modules+ni+instruments&source=lnms&tbm=isch&sa=X&ved=0ahUKEw...:

Does that help in producing a signal of 1MHz?

Thanks you all
