Generate waveform in .wdt file

[NANONFSMW]

Hi guys,

I am going to generate a sine wave signal along with uniform white noise in a .wdt file. And I would like to import this .wdt file to Arbitrary Waveform Generator to output on a external oscilloscope. Any suggestions how can I achieve it?

Thank you!

Hi Nanonfsmw,

I'm not aware of the .wdt file format.  Is this a file format used by your external oscilloscope?  Did you just mean a waveform data type in LabVIEW?  In addition, It would also help a great deal if you could let me know what National Instruments hardware you're using?  If you're using one of our function generators, I would recommend taking a look at our arbitrary waveform shipping examples.  These can be found in the example finder in LabVIEW (Help » Find Examples » Hardware Input and Output » Modular Instruments » NI-FGEN » Arbitrary Waveform Generation).  There is also a vi called "uniform white noise.vi" that can be used to generate the noise to be added to your sine wave.  If you're not using one of our function generators, I would recommend looking through our example finder under your product type for examples.  For DAQmx devices, I would look in the section at the Cont Gen Voltage Wfm-Int Clk.vi example (Hardware Input and Output » DAQmx » Analog Generation » Voltage).  This will allow you to output your sinewave signal added with uniform white noise to your external oscilloscope.

I hope this helps,
Paul C.

Thanks for your reply, Paul C

I really appreciate this.

.wdt format, I think it stands for "waveform data type". I am having NI ELVIS and there's a application called "Arbitrary Waveform Generator" and it takes such kind of file format. Finally I found I could use one program came with NI ELVIS as well, called Waveform Editor, to edit some waveform I would like to use. All I have is only an ELVIS and my laptop installed LabVIEW. Thanks for your suggestion to look at DAQmx vi example. I will take a look at it. Thank you again!
