Abstract : A scan oscillator and a Pulse Repetition Frequency (PRF) oscillator with associated analog and digital circuits provide the drive signals for two different RF PIN diode attenuators. When driven by a portable Gunn Diode Oscillator or other microwave source RF is generated that provides main lobe and adjustable side lobe radar signals to a directional microwave antenna. This output signal has adjustable scan rate, beam width, PRF, pulse width, and side lobe level and is self-contained in a package measuring 8 and 3/8 x 7 and 3/8 inches. The system allows on the sail testing for periscope mounted Direction Finding Systems.
