HYBRID AUTOMATIC TUNING/MATCHING FOR NMR PROBES

摘要

Remote adjustment of a selected one of a plurality of adjustable NMR probe circuit components is achieved with a plurality of selectable linear actuators, the selected one of which urges a platen against a respective driven gear, azimuthally locked to its shaft, to displace it axially along that shaft. When the driven gear engages a driving gear a single driving motor is energized and controlled to effect the desired adjustment.
