Synchronizing Analog Output to Counter Input

Hi!

 

I'm really new to LabView. Pls help!

 

I'm trying to obtain a set of stimulus signal and response signal from my motor for system identification.

 

The stimulus signal will be generated by the Ao0 channel and response signal (quad encoder linear position) will be read into counter0.

 

How can I synchronize the stimulus signal and response signal so that the sampling (n samples) for both stimulus and response starts at the same time?

 

e.g.

 

t=0, stimulus sample 1, response sample 1

t=1, stimulus sample 2, response sample 2

.

.

.

t=2000, stimulus sample 2000, response sample 2000 

 

I've attached my VI.

 

Thanks. 

 

Regards,

Student
