High speed data aquisition

[12312e]

hi

        I am using cRIO 9004 RT, 9104 FPGA and 9215 I/O module(100KS/s) for high speed data aquisition. But i am unable to obtain 100KS/s properly using the attached VI. please give me possible solutions.

Thanxs in advance

Hello Sooraj!

I would recommend you to make use of DMA in order to achieve the transfer speeds you are requesting. The method you have chosen with synchronous display will not work well here. Information about DMA can be found below in the links I have provided.
