Data Gathering
Turn off the white noise source.
Run the LabView vi. You should still be able to find your resonance peak. It may, however, be buried in more noise than originally expected.
Turn OFF any nearby unnecessary electrical equipment (an Oscilloscope has a nice operating frequency of 44 kHz which looks great in the results). Doing so may help mitigate extraneous noise.
Consider low frequency values, and observe a peak at 60 Hz (as well as at many of its harmonics). This is the frequency of the line voltage in the room. Also, observe the 1/f noise.
