AR-133 special modes of opera ? on: disciplined to an external 1pps: this improves the long-term-stability, the accuracy, and synchronizes the phase of the 1pps ou tput to the 1pps input. power-saving modes (op ons): for applica ons where power is limited, the ar133a o ? ers several power saving modes to be selected by the user. ? mixed mode (op on) - in this mode the physics package, which is the main power consumer, is turned on and o ? periodically, allowing lower average power consump on. in this mode the internal ocxo supplies accurate frequency calibrated to the atomic clock frequency. although performance is slightly reduced, power consump on is signi cantly lower in this mode. ? ocxo disciplined mode (op on) ? this mode implements an ocxo disciplining to external 1pps (with physics package shut-down) and consumes even lower power of about 1.8 w AR-133 rev 1.2 mar 2016
