Measuring frequency and amplitude of analog signal with Labview


I'm preparing for a lab where I will measure the frequency and amplitude of a tuning fork optically. From my setup, I will get a signal corresponding to the number of millimeters of displacement the tuning fork currently has. I expect this signal will look like a sine wave and that the amplitude will decrease over time.

This is the signal I will send to LabView via GPIB. It will probably have some noise. What is the best approach to find the frequency and amplitude of the signal?

How do I implement this in LabView?
