Abstract :
In order to improve the stability of the Fermilab Booster low-level RF system, a numerically controlled oscillator system is being constructed. Although the system has not been implemented to date, the design is outlined here. The heart of the new system consists of a numerically synthesized frequency generator. The 3 GHz/s rate and 30-53-MHz range of the booster frequency program required the design of a CAMAC-based, fast-cycling (1-MHz), 65-KB×32-b, digital function generator. A 1 MHz digital adder and 12-b analog-to-digital converter will be used to correct small program errors by phase-locking the oscillator to the beam
