generate a tone burst

[bodino]

Hei

I am trying to generate a tone burst signal. It is a 5 cycles sine wave (with a hanning window). See the attached document.
I am using a NI 5401 with the function generator NiFGEN.
I only need to generate this signal one time. I can't manage to get only one signal, the NiFGEN repeat this signal.
Somebody have any clues about this?

Thanks

Olivier

Hi,

May be niFgen_Sweep_generator_example.vi located in the Labview library can help you... I do not have the board to test it but it seems that you can set the duration of your generation. Maybe you can use a sequence structure to generate one period and on the others periods generate a DC = 0V.

Hope it will help you,
Regards

Thanks David

I tried with the example you show me. It is not raelly what I want because I don't want to sweep the frequency. But there is still the same problem: the niFgen generator is repeating the signal. I just want to send only one signal. If you have another clue, let me know.
