Figure 1.3
shows the typical Allan Deviation when using the optional, ultra-high-stability
double-oven OCXO. Note the significant stability improvement for time periods above 1s
measurement intervals when using the double-oven OCXO option as compared to the standard
OCXO
It can be clearly seen from
Figure 1.3
that the FireFox Signal Generator equipped with the
ultra-high-stability OCXO option achieves better than 1E-12 timing stability in less than 10 hour
measurement intervals when locked to GPS.
The rear panel 1PPS output of the FireFox Signal Generator is driven by the Motorola M12+ GPS
timing receiver. The 1PPS BNC output is only active when the unit is locked to at least one satellite.
See
Figure 1.4
for a typical Frequency Stability measurement of the FireFox 1PPS output when
compared to an ultra-high-stability reference. It can be seen that the FireFox 1PPS output can achieve
about 1E-12 timing stability in less than 24 hour measurement intervals when locked to GPS. The
FireFox Signal Generator already achieves this excellent stability with the default OCXO.
