Timebase
Timebase Uncertainty = ( Aging + Temperature + Calibration Uncertainty )
1. All Timebase Aging Errors apply only after an initial 30-days of continuous powered operation and for a constant altitude ±100 m.
2. Only use the Factory Calibration error values for the period before your first re-calibration. Factory Calibration uncertainty includes
3. Warm-up error applies when the instrument is powered on in a stable operating environment.
4. Retrace error may occur whenever the instrument line-power is removed or whenever the instrument is battery operated and the

the instrument settability error, the factory calibration source uncertainty, and additional timebase uncertainty due to factory
calibration before the required initial 30-days of powered operation. Settability defines the resolution increments you can reach is in
steps of 0.1 ppb (0.01 ppb on Option 010).
When moved between different operating environments add the Temperature error during the initial 30-minutes of powered operation
battery fully discharges. Retrace error is the residual timebase shift that remains 72-hours after powering-on an instrument that has
experienced a full power-cycle of the timebase. Additional frequency shift errors may occur for instrument exposure to severe
impact shocks >50 g.
