  • Efficient remote transmission line probe tuning for NMR apparatus
    Patent number: 4916398
    Abstract: The invention demonstrates remote tuning of an NMR probe over a length of transmission line while retaining very high efficiency relative to the equivalent locally turned coil. Fixed capacitances for partial tuning are employed at the load such that a desired range of efficiency is achievable for a selected range of capacitance values at both load and source for the intervening transmission line.
