Hi WooYee,
As conversed on the phone yesterday, we tested and found that the scanning takes 3.26 - 3.27 sec.
I'm posting here to share this information with the community.
Please note that the scanning speed is dependent on the processor speed, since the calculation is done in the software.
The above test result was produced by a PXI-8105 controller, with 2GHz Intel Core Duo 2 processor, 1GB (512MB x 2) RAM and LabVIEW 8.5.1.
