I'm using DASYlab to acquire data from a cyclic test using an USB-2537 DAQ card. I have an issue when trying to acquire at higher sampling rates. When using a high sampling rate (10 kHz) with a small block size (10), the data is not treated by the computer, the update of the digital instruments, graphs etc. gets extremely slow, finally resulting in a overflow in the DAQ module.
When I increase the block size (1000) everything runs smooth, BUT a bock contains always identical values, resulting in a stair case and decreased resolution depending on the frequency of the signal.
What is wrong? It is very urgent, since I have a project deadline on Monday. Thanks for you help!
