How quickly do you need to control that stepper motor? How fast do you want to measure your resistance? What is the range of the resistance you are going to measure?

It is not possible to control a stepper motor directly with a DAQ interface. You wil need some additional hardware such as a stepper motor driver and a power supply for the latter.
Once you selected a stepper motor driver unit, the control possibilities depend on the interface between the stepper motor driver and the control system. Some will need pulses for each step and a logic level for direction control (and with these you have to write your own accelaration and deceleration. Others use an advanced data protocol and you just have to transfer parameters for motion control.

since you are obviously a newbie concerning stepper motors, reading some introductional papers might be helpful for you.
