Abstract :
This paper describes a microwave sweep frequency oscillator operated by means of a microprocessor. The frequency of the oscillation depends on the control of a YIG (Yittrium Iron Garnet) filter and an electronic phase shifter placed in a closed loop with amplifiers. The frequency is controlled directly by a Rockwell AIM 65 microprocessor in both fixed-and swept-frequency operating modes.
