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.

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 of over 25 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.
