Analog Output buffer delay

[Bebo977]

I need to generate a different (different in lenght)waveform each iteration
I use a dubble buffer analog output like in diagram attached. the waveforms in output have a delay equal to output buffer lenght. I try to inizialize the first buffer with a wave that fill the buffer but no change in delay. Someone has suggestion? Better if someone explain me with a diagram! thank's to all.

Hello,

I�m certain of what you mean when you say that �the waveforms in output have a delay equal to output buffer length�. Do you mean that the output waveform values should be changed and the buffer size should stay the same size? Or do you want to add new waveform data to the end of the waveform you created with the Initialize Array VI?

Thanks,
