Abstract
The transceiver of an NRM instrument includes a digital synthesizer that produces an analog carrier signal which can be controlled in both frequency and phase and which can be frequency and phase modulated. The analog carrier signal is mixed with reference signals to boost its frequency to the Larmor frequency of the instrument.
