9401, 2 encodeurs and sampling recording

$

Hello 

I have a NI9401 on a C-DAQ9171. 2 optical encoders are connected to the 9401.

 

My problem is that I want to make an internal timer, in order to be able to record the data with a sampling rate that I can easily change.

 

Thus, I should configure 2 counters for the input corresponding to the 2 encoders, and another counter to make the "internal" clock,  which will allow me to have a valid sampling requency (1000 hz) for example.

 

I have watched many topics about that, but I still don't manage to do that. (I am new to labview..)

 

If anybody could help I would be very gratefull.

 

Sincerely.

 

Jeff
