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.
threshold.
Ttttttt.ttt - Time Interval; tttttt.ttt is the time interval (0 to 999999.999 microseconds) of the last
1 PPS event.
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.
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.
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.
