It is intended to generate a signal 1pps, synchronized with UTC. This signal is used as a reference signal to adjust the frequency of the rubidium standard to the nominal value. For user convenience, it has two 1 pps SMB connectors (one from the GPS receiver and the other from the frequency standard) and one 1 pps signal from the GPS receiver on the DB-15 pin for internal use.
In the presence of GPS / GLONASS signals, this device provides the operation of the rubidium frequency standard in a disciplined mode with a frequency error of not more than ± 5.10-12
