I have LC-tank with resonance frequency Fres = 5MHz approximately.
1. Can I use the less frequencies (3 Mhz, 2Mhz) to work? Or I should use the frequencies near Fres only?
2. I want to know in which frequencies I can measure with max efficiency (max sensitivity for small debris). I think it must be the highest frequency for nonmag debris and low frequency for mag debris. In this case should I have the different LC-tank?
3. Is the uC Sampling rate (from main window of GUI) and the output data rate the same parameter?
