The measurement of the phase between two sine signals with NI 6251

[Dimon87]

Hi, I am working with NI 6251. I need to measure the phase between two sine signals. I used "Tone Measurements" on each signal and then substracted there phases, but the result was  incorrected. Please, help me to solve this problem.

How can I know the time, when sine signals will cross the zero at first?
