I am using the pico 2204 and Labview 2011 to make a spectrum analyzer with FFT, Thd, SNR and afew other functions. I have both channels reading a signal using the faststream vi, but I don't know how to get the built in function generator to operate. Is there a vi that is made for this? If so could you give me any info on where to place the block in faststream or what I need to do? I am new to Labview.
