PCI 6115 analog trigger acquisition with onboard memory

Hello all,

I'm trying to perform a multi-acquisition of finite samples (4096 @ 10 MS/s) in a 4 channels PCI 6115 (64 MB buffer) using Labview 8.2.1. I use a vi similar to "Acq&Graph Voltage-Int Clk-HW Trig Restarts.vi"  using instead an analog trigger with pretriggered samples (DAQmx Start reference Analog edge).
This works quite well, but I noticed that when processing the signal in the while loop using Analytic wavelet transform the acquisition rate decrease exponentially with the number of scales for WT coefficients calculation.
I was wondering if It is possible  to store the data in the card buffer and to transfer progressively the data to PC to be treated in the vi (what means to have a delay display of acquired data whereas the PCI card continues to acquire data).

Thanks for any help that you can provide.

Regards
