EQUIPMENT FOR SELECTIVE EXCITATION IN NMR-SPECTROSCOPY - ENHANCED TECHNIQUES FOR RADIOFREQUENCY MODULATION AND DIGITAL PULSE-SHAPE GENERATION

Abstract:

This paper describes readily constructed electronic equipment for generating shaped pulses for use in nuclear magnetic resonance spectroscopy. A radio-frequency modulator is controlled by the analogue waveshape supplied by a digital waveform generator. The modulator makes use of a double-balanced mixer in a circuit, which extends its linear range. Both the modulator and the digital section embody enhancements over conventional techniques. The equipment was designed to be integrated into Bruke...
