data acquisition over a window

[poli]

I am trying to acquire data using LABVIEW 2009  from   NI- PCI 6024E DAQ.

The data has to be acquired every 10 sec, over a 2 sec window @ 1KHz.

That means, the data is acquired  @ 1KHz only at t= 9-11s, 19-21 s, 29-31 s and so on.

The average value of the data obtained over such  a 2 sec window is  saved in a file.

How do i implement this?

Could i use the DAQ assistant?

Any suggestions would be gratefully appreciated.

Regards

Hi,

Take a look at this thread: Link.

Check the post and attachment from user:  rpursley8. You have to make some changes to it, it's not quite the same, but it's similar.

Use Sample Clock VI to define the Sampling Rate (1kHz) and the Number of Samples (for two seconds you need 2000samples).

Use a Counter Output to generate your trigger signal (10seconds) connectic its output to Start Trigger (Digital Edge) "Source".

You have to set True the DAQmx-Trigger Property ReTriggerable.
