Abstract
A nuclear quadrupole resonance (NQR) or nuclear magnetic resonance (NMR) apparatus which includes a probe and a variable impedance spectrometer. The probe emits a signal towards a specimen which causes the specimen to produce a resonance signal. After a recovery period from emitting the signal, the probe receives the resonance signal produced by the specimen. The variable impedance spectrometer is connected to the probe and has a total Q factor therewith. The spectrometer causes the total Q factor during the recovery period to be lower than the total Q factor before and after the recovery period by varying the impedance of the spectrometer, without changing the electrical configuration of the probe.
