Abstract
This invention is a multiple-frequency signal generator apparatus and method primarily for simulating a cell site interference environment for electromagnetic communications systems. The generator can produce a plurality of frequencies having a frequency-spacing of d cycles per second. The invention comprises a single frequency multiplier, at least three oscillators and two mixers for providing a multitude of frequencies closely spaced about a carrier frequency. The simple design and components avoid complexity and save costs.
