- In field B apply RF field to material at Larmor frequency ω_0
- Coil of L_0 perpendicular to B_0 to induce spin flip
- LCR circuit (so that ω_0=1/√LC ) to observe change in impedance with frequency
- As frequency changes: circuit response to Q-curve and polarization signal
- Sweep frequency around ω_0 to integrate in ω.

- nλ/2 cable length: leads to steeper Q-curve, making smaller polarized signals much more difficult to analyze using traditional background subtraction and signal extraction methods.
- Q-meter configurations (calibration constant)
- Changes in Radiofrequency Radio frequency (RF) environment
- Temperature Change
- Statistical errors dependent on DAQ
