A scan oscillator and a Pulse Repetition Frequency (PRF) oscillator with associated analog and digital circuits provide 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 83/8x73/8x3 inches. The system allows "on the sail" testing for periscope mounted Direction Finding Systems.
