A SIMPLE RF PHASE DETECTOR FOR NMR SPECTROMETERS<br />

Abstract<br />

A phase detector system which can be easily adapted to bridge or<br />

crossed coil NMR spectrometers is described. Modifications to the NMR<br />

spectrometer include addition of a constant impedance attenuator for<br />

control ~ the probe excitation voltage, a leakage control system<br />

independent of probe balance, and a differential dc amplifier to cancel<br />

changes in the leakage from spurious modulation of the transmitter<br />

power.<br />

Copies of the circuits directly applicable for a V4310 transmitter/<br />

receiver unit are available at the address below.<br />
