Synchronize Counter input Analog input

[Trainee123]

Hello,

I am trying to mesure the velocity of a motor by counting the edges from an encoder that output a 5V TTL signal, using counter input of a NI 9401. I am also trying to mesure the torque of the motor by using analog input of a NI 9251. The thing is I couldn't manage to acquire the two data in the same time domaine and write to a text or tdms file. 

Anyone has any idea how to do so? I have attached my vi. I am open to any suggestion!

Hi,

I remember doing it like this: Synchronize Encoder Counter Input and Analog Input

It could be, though that DAQmx is so advanced nowadays that you don't even have to jump through all those hoops...
