Frequency Response Function (Mag-Phase) VI
Computes the frequency response and the coherence based on the input signals. Results are returned as magnitude, phase, and coherence.

Typically, time signal X is the stimulus, and time signal Y is the response of the system. Each time waveform corresponds to a single FFT block. You have to pass each time waveform individually to this VI.
