摘要:
An adjustment device (1) for an RF resonant circuit (96) of an NMR probe (90) has a plurality of movable elements (6) which are arranged in succession, such that adjacent movable elements mutually engage, so as to be movable relative to one another in a limited range. The movable elements each have at least one electrical functional part (20; 20a-20b) for adjusting the RF resonant circuit. N outwardly oriented electrical contact elements (15; 15a-15b; 23, 24) include at least two functional part terminals (21, 22), and the electrical contact elements are each connected to a functional part terminal. The adjustment device also includes a first connection assembly (11) for slidingly contacting at least a portion of the movable elements from outside, to contact the contact elements in dependence on the movement position of the movable elements, as well as a movement device (4), configured to move one of the movable elements.
