    keyword=EPR Calibration @ Transverse Pumping

    After changing to EPR pumping, an EPR measurement if performed:

    D2 Output : ~-30mV
    RF Amp : -10 dB
    Gain : 0.9
    Int Gain : 1.7

    3 EPR FM sweep resonance is observed. The K39 resonance is screen shot
    below. Then there was an successful EPR AFP sweep, which showed that

    Pol. = 28.2%

    An NMR field sweep is followed, which give a 13mV NMR signal from
    Vertical Pickup Coil. So calibration constant is

    Pol. = 2.17%/mV * Vertical pickup NMR @ empty target position
