    摘要： The RF probe of a quadrature sensitive FT-NMR spectrometer is tuned and matched to its electrical environment by utilizing the phase quadrature sensitivity of said spectrometer to function as an impedance vector analyzer for the probe in situ. Phase and amplitude measurements of the in situ probe are compared to an occasionally measured and stored amplitude and phase characteristic observed when the probe is replaced by a 50 ohm terminator.

    摘要： An RF probe for a gyromagnetic resonance spectrometer includes a coil cage for supporting the probe coil preferably within the cage formed of a number of rod-like members displaced parallel to the coil axis and spaced apart from the axis at a constant distance. Access to the coil through an axial continuous slot 46 or equivalent eliminates axial discontinuity in susceptibility due to discrete holes in the coil form.
