Title: Nuclear magnetic resonance field meter - has probe in magnetic field and H.F. oscillator tuned by capacitance diodes
Inventor: WINTERHOFF HORST DIPL PHYS
IPC: G01R33/24
Filed: 1973-12-07
Abstract: The diodes are controlled by a sweep generator trigger with a following tuning integrator. Two h.f. coils inserted one in the other are provided in the probe. Their axes are at right angles to each other. When the integrator tuning voltage reaches at the time (t) its maximum corresponding to the range end, it switches a range trigger output to a positive potential. This pulse connects or disconnects an inductance in the probe or in the oscillator, corresponding to the next measurement range. At the same time the output of the sweep trigger is blocked up to a time (t"), and this positive potential is also applied from the time (t) to the tuning integrator input, until its output voltage is reset to the lower threshold at a time between (t) and (t"), and disconnects the range trigger.
