Abstract:

A small, battery-operated test instrument has been built for quick adjustment of the carrier frequency oscillators of FM tape recorders. The instrument uses integrated circuits, miniature components and printed circuitry. It is small, light, inexpensive and dependable. The method of measurement could be applied to other problems where an unknown frequency must be compared with a reference. Author
