Operating Manual
Operation
Description:
Rx - Rubidium lock; x=0 not Locked, x=1 Locked
Dx - Discipline On/Off; x=0 discipline off, x=1 discipline on
Px - 1 PPS input present; x=0 not present, x=1 present
Vx - Valid 1 PPs; x=0 unstable, x=1 stable. Time change in the 1 PPS is less than the rate
threshold.
Ttttttt.ttt - Time Interval; tttttt.ttt is the time interval (0 to 999999.999 microseconds) of the last
1 PPS event.
Sssssss.s - Seconds Counter; ssssss.s is the second count (0 to 999999.9 seconds) since
the unit has been turned on. The count will roll over to zero when maximum is reached.
Eddddd - DAC value; ddddd is the DAC value (0 to 65535), and is proportional to the voltage
applied to the oscillator.
Hhhh.h - Temperature count; hhh.h is the dithered temperature sensor value.
Ggg.g - Dynamic Gain; gg.g is the current value being used in the disciplining algorithm for
dynamic gain.

Description:
The oscillator discipline is turned off. The Rubidium control voltage (DAC value) will remain
constant.
