    Many complex electronic systems require a stable, highly accurate timebase. Communication, automatic test and measurement, and precision time-measurement systems all require accurate frequency standards. Traditionally, users have looked to atomic clocks (cesium) for high stability and accuracy. With the FS700 LORAN-C Frequency Standard, cesium-clock stability is now available at a fraction of the cost of atomic standards. The FS700 serves as a NIST traceable frequency reference in the US, Europe and Asia.

    Cesium Stability

    More than 50 LORAN-C transmitters are maintained throughout the Northern Hemisphere by the US Coast Guard. The timing of their transmissions is controlled by cesium clocks located at each transmitter site. The FS700 extracts the timing information from the transmitted signal and uses it to frequency-lock its own highly stable oscillator. The result is a 10 MHz output signal with the same stability as the cesium clock used to generate the LORAN-C transmissions.

    Frequency Outputs and Phase Detector

    Four 10 MHz sine wave outputs are available at the rear panel of the instrument, and an additional front-panel, adjustable frequency TTL source is also provided. A built-in phase detector measures the phase shift between an external timebase and the internal frequency source allowing you to easily calibrate precision oscillators between 100 kHz and 10 MHz. The FS710 distribution amplifier can help you distribute the 10 MHz reference signal throughout your facility.
