Premium GPS Time & Frequency Standards for Unmatched Accuracy

Designed for mission-critical applications, our Meridian II & Tycho II are based on a high-reliability platform with a conservative MTBF up to 30+ years. These products provide the most precise and stable, GPS-synchronized, time & frequency outputs in the world. They are supported with free software upgrades and free lifetime technical support.

Time & Frequency Standards

PRODUCT FEATURES

  • Timing Accuracy is < 10 ns to UTC(USNO) when locked.
  • Frequency Accuracy is < 6 x 10-14 to UTC(USNO) for 100,000 seconds.
  • No frequency steps - guaranteed.
  • Reliable MTBF up to 30+ years.
  • High-bandwidth NTP server (7500 packets per second).
  • Dual-gigabit Ethernet ports with security-hardened network interface and protocols (SSH, HTTPS, SNMP V3).
  • 1PPS and Time Code are standard outputs. Many options are available.
  • Modular, plug-and-play architecture supports up to 5 option modules in a 1U chassis. 2U chassis available.

We Fully Specify Performance

We fully specify the performance of our products and we back it up with measured data and a test report from the National Institute of Standards & Technology (NIST). None of our competitors fully specify their product or publish third-party data from a national standards lab.  Click here to read a Meridian II test report from NIST.

Sample Specifications

Following is a sample of our specifications when using a top-of-the-line Ultra-Stable OCXO:

  • Timing Accuracy is < 10 ns to UTC(USNO) when locked.
  • Frequency Accuracy is < 6 x 10-14 to UTC(USNO) for 100,000 seconds.
  • Frequency Stability at 1 second is < 4 x 10-13.
  • Phase Noise at 10 MHz is < -113 dBc at 1 Hz and < -153 dBc at 10 kHz.
  • Harmonics at 50 ohms are < -45 dBc.
  • Holdover is < 6 us at 24 hours.
  • No frequency steps - guaranteed.

Many Options Available

Oscillator Options: TCXO, two grades of Rubidium and three grades of OCXO.

Other Options: Low Phase Noise Outputs, Sine Wave Outputs, Telecom Outputs, Pulse Rates to 10 MPPS, Alarm, PTP/IEEE-1588 Grandmaster, Programmable Pulse Outputs, additional Time Code Outputs, -48 Vdc Power and much more.
