If you need oscillators that provides an output waveform at a specific frequency, then you have come to the right place, Frequency Management Inc. FMI currently supplies oscillators to a variety of market segments including; industrial instrumentation, optical networks, process controls and telecommunications. When a crystal is placed into an amplifier circuit, a small amount of energy or voltage is fed back into the crystal, which causes it to pulse or vibrate. These vibrations act to stabilize the frequencies of the oscillators. For more than thirty years, Frequency Management has been supplying quick delivery and tight tolerance to the communications market.
