Time & Frequency Standards
We can reliably provide you the most precise and stable GPS-derived time & frequency equipment in the world.
We can reliably provide you the most precise and stable GPS-derived time & frequency equipment in the world. These products are specifically designed to perform the best in terms of accuracy, stability, low phase noise and holdover. Following is a sample of our specifications when using our top-of-the-line Ultra Stable OCXO:
- Timing Accuracy is < 10 ns to UTC(USNO) when locked.
- Frequency Accuracy is < 6x10-14 to UTC(USNO) for 100,000 seconds.
- Frequency Stability at 1 second is < 4x10-13.
- 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.
Oscillators & Frequency Steps
We have been selecting and tuning precision frequency control componentry for 35 years. During that time we have learned which components to use, and if we don't make them ourselves, we know where to get the best. One component at the heart of every good frequency standard is an oscillator, either quartz or rubidium. We've learned that most quartz oscillators suffer from frequency steps that cannot be mitigated by any software algorithm. The oscillators that we manufacture for use in our time & frequency standards are selected to be the absolute best in their class - no frequency steps - guaranteed.
We've Made Precision Frequency Standards for Decades
Our engineering team includes the designer of the first microprocessor-controlled disciplined frequency standard which was introduced in the 1980s using Loran-C signals. Since then we have created leading GPS-based standards and pioneered the use of CDMA for these applications. We have extensive experience with every broadcast RF signal source that has been used to discipline oscillators and provide precise time & frequency outputs. The products we are building today are the culmination of this legacy of experience in dealing with real world signal reception anomalies and oscillator behaviors.
A LEAP SECOND IS PENDING - this doesn't work & its not needed on this page.
