How to modulate a signal and output it from the AO of Ni DAQ cards

[kaiqujian]

Hi, there,

Now, I have a Ni6052 DAQ card. There are some examples to output sine signal from analogue output of the cards. But how to output an modulated signal?

Now, I need to use this card to output a modulated signal which could be described: sin(r)*sin(θ) and I attach the graph of such a modulated signal.

Thanks

Hi kaiqujian,

      First build the list (AKA "Array" ) of values that should be output, then Write them (for instance, see example "Cont Gen Voltage Wfm-Int Clk.vi".)

The attached VI may give you some ideas.

Cheers!
