Description

The Meridian Precision GPS TimeBase is a frequency standard that provides the most precise and stable, GPS-synchronized, time & frequency outputs in the world. A study of the specifications of our competitors' products, including SAASM, shows that they are unable to match the accuracy and stability we deliver in the Meridian. The Meridian uses our individually characterized precision oscillators and software algorithms developed over 30 years of engineering experience in the frequency control industry. These algorithms steer the outputs and isolate them from system anomalies, providing you with unmatched precision and accuracy. The modular, solid state design yields a conservative MTBF of 25 years and accepts a wide range of field-installable options. - - - - - - - -Low Phase Noise Outputs, Telecom Outputs, 10 MPPS, Pulse Rates, Additional Time Code Outputs, Alarm, -48Vdc Input, PTP/IEEE-1588 Grandmaster and more. Oscillator Options The Meridian can be configured with a complete set of oscillator options ranging from a low-cost OCXO with SC-cut resonator to a state-of-the-art compact Rubidium unit. An ultra-stable OCXO with SC-cut resonator provides metrology grade short term stability, excellent phase noise, temperature stability and ageing. Click here for datasheet. Low Phase Noise (LPN) Output Option This option provides four isolated, 5 or 10 MHz, frequency output signals with exceptional spectral purity. The Meridian is designed to support up to five option modules which will provide 20 LPN outputs. Careful attention to power supply filtering and signal routing preserve the same high-performance phase noise and spurious noise characteristics as the source oscillator. Click here for datasheet. Telecom Clock Output Option This module provides two outputs which can be any combination of E1, T1 or Composite Clock. The Meridian is designed to support up to five option modules which will provide 10 telecom clock outputs. An alarm output is available as an additional option. SSM is supported. Click here for datasheet. Programmable Digital Output Option This module adds four independently programmable outputs to your Meridian Frequency Standard. The Meridian is designed to support up to five option modules which will provide 20 outputs. These buffered outputs can provide user-selectable, on-time pulse rates from 1 PPS to 10 MPPS, or a digital timecode output. An upgrade provides access to the Meridian DDS with rates from 1 PPS to 10 MPPS in 1 PPS steps. The synthesized rates are phase-locked to the system oscillator. Click here for datasheet. Analog Timecode Buffer Option This module provides four time code outputs. The Meridian is designed to support up to five option modules which will provide 20 buffered timecode outputs. The user-selectable format can be one of either IRIG-B122, IRIG-B123, IRIG-B IEEE-1344 compliant, NASA-36, or 2137. Click here for datasheet. More Options Several other output options are available.
