<p>The invention demonstrates remote tuning of an NMR probe (51) over a length of transmission line (56) while retaining very high efficiency relative to the equivalent locally tuned coil (50). Fixed capacitances (52, 54) 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 (56).</p> |
