GPS Frequency Reference offers atomic clock stability.
Press Release Summary:
Designed to operate in conjunction with GPS or compass satellite signal, Model IQFR-100 delivers frequency accuracy of < ±1E-12 after 24 hr of stable satellite signal lock. In event of signal loss, unit maintains accuracy of better than 5E-11 until restoration of lock due to internal reference oscillator. Housed in 1U rack mountable cabinet, IQFR-100 provides two 10 MHz square wave outputs, 2 square wave outputs at 2.048 MHz, and two 1 PPS impulse outputs with holdover specification of ≤1.5 µs.
Original Press Release:
Embedded World Launch for IQD's New Atomic Clock Stability GPS Frequency Reference
The new IQFR-100 high precision GPS frequency reference from IQD delivers a frequency accuracy of < ±1E-12 after a period of 24-hours stable satellite signal lock. This is similar to the stability levels of much more expensive caesium atomic clocks.
Intended primarily for use in applications such as communications systems, power grid references, national defence equipment and smart metering, the system is designed to operate in conjunction with either a GPS or Compass satellite signal. This allows the frequency reference to maintain a high stability in the event of signal failure by virtue of the high performance internal oven controlled crystal oscillator. In the event of a loss of signal, the unit maintains an accuracy of better than 5E-11 until restoration of lock due to the internal reference oscillator.
Housed in an industry standard 1U rack mountable cabinet, the IQFR-100 provides for a number of output interfaces. This includes two 10MHz Square wave outputs (accuracy < 1E-12); two square wave outputs at 2.048MHz, again with an accuracy of <1E-12; and two 1PPS impulse outputs with a holdover specification of ≤1.5µs in the event of the loss of the satellite signal.
Consuming <7 Watts of power whilst operating from a standard 220V AC supply line, the IQFR-100 has an operating temperature range of -20 to +60 degrees C. In the event of a power outage failure at the mains source, an internally rechargeable battery switches in to maintain system stability performance prior to restoration of the supply. The various outputs are presented via back panel BNC connectors in addition to a standard aerial connector. Various front panel LED lights indicate lock of the satellite signal as well as system fault conditions.
