waveform generator question..

[KowdTek]

I've attached a vi to start with a vibration profile. This is something new to me so "please" bare with me..

The idea is to get the inverse fft of the profile and input it to a voltage wfm generator (Hardware Input & Output - DAQmx - Voltage - <one of the wfm generator examples>). In the attached vi, can I just wire the psd output after the for loop to inverse fft vi? and how can I go from there to connect its signal to waveform generator input?

Thanks in advance..

KowdTek,

To do the Inverse FFT, you can simply use the attached VI.  I have also used a Build Waveform function to give you your waveform.  This particular waveform starts at 0 (default), and has a time step of 0.1 seconds.  To output this, use one of the examples, but replace the waveform generation subVI with your waveform.  You will probably also need to change the DAQmx Write VI to Analog » Single Channel » Multiple Samples » Waveform.

Hope this gets you started!

Drew T,

Thank you very much...
