A periodic random waveform generation for my project

Hi,

         I am trying to generate a certain wave-pattern with some AC noise on top of it with the software "Labview" for my project purpose. Can anyone please help me why I am not able to generate the noise signal (termed as random in the output window) upto the duration of the signal of the "Noisy_waveform.vi" file. For the reference, I have attached here all the necessary probe points as well. 

 

Thanks & Regards,

Varindra

It's impossible to run and debug a word document. Attach the actual VI.

Since the duration of the noise signal is smaller than your signal duration when you add the two the result is the same duration of the shorter signal, in this case the noise signal.

Hi,

           Please find the vi file attached.

Herrlin is correct. Your white noise signal is only 128 samples long and the arb signal is 4001. Use the From Dynamic Data/Get Waveform/Array Size on the arb signal and pass the size to the while noise function to set number of samples.

Hi,

       I need to generate a bin file from vi file (in labview). Can anyone please tell how can I create the bin file. And subsequently I need to import to NI 5421. Will this bin file directly be downloaded into the the card or I need to setup some process.

 

Thanks & Regards,

Varindra
