Informatie:
                                    The FS700 LORAN-C Frequency Standard produces a highly stable
and accurate 10 MHz output by locking an internal crystal
oscillator to
the Cesium clock controlled LORAN-C radio transmission. The
FS700
system consists of a receiver, containing amplifiers,
filters, and data
acquisition circuitry, and a remote antenna, with an
internal preamplifier.
Data acquisition circuitry allows the FS700 to frequency
lock its internal
oscillator to the third positive zero crossing of the LORAN-C
transmission. In addition to providing an ultra-stable 10
MHz output, the
FS700 also provides a user selectable TTL compatible frequency
output in the range of 0.01 Hz to 10 MHz in a 1, 2.5, 5
sequence. An
internal phasemeter circuit allows precise frequency
calibrations of
other oscillators in the range of 100 kHz to 10 MHz.
