The FEL-10 is a low noise distributed 10 MHz frequency reference. The device
can be used to provide a stable and spectrally pure 10 MHz reference. The FEL-10
can be phase locked via a +/- 5 VDC tuning signal or phase locked to an external
10 MHz 1VRMS signal. The unit incorporates a low noise OCXO and the high
performance distribution amplifier module, HPDA. Five outputs are available with
channel to channel and reverse isolation exceeding 100 dB. The FEL-10 is offered
in a stand-alone rack-mount enclosure with SMA connectors. The optional PLL
module allows locking to an external 10 MHz source. The PLL module has loss of
reference and loss of lock indicators.
