Independently triggered simultaneous signals using the matlab daq toolbox session based interface with nidaq USB-6259?

Hello All,

I don't have any experiences with the session based interface daq. Is it possible to generate multiple analog outputs using a nidaq USB-6259 that are timed differently? I would like to generate an analog signal (30 mins of continuous random noise using appropriate memory buffers) that is presented simultaneously with a shorter 200 ms tone burst that can be triggered independently from the first noise signal. With two session based analogout objects, can I use background trigger events to trigger the two signal types independently?

Thanks for your input

To check: does this involve a single channel that is to receive all data, or instead one channel for the noise plus another channel for the tone burst ?

I hope to use two different analogoutuput channels for the the noise and tone burst.
