i am trying to sample 2khz signal at 8khz,with an accuracy upto 6place of decimal ,using pci 1200 DAQ card.

[AB 8]

how can i externally trigger this operation.i need to sample my signal at 4 points and store it in a excel sheet and the values should be same,as the the 2khz signal and the 8 khz signal both are comming from the same source.
