Tycho GPS Frequency Reference
Our Basic GPS Frequency Standard
For Unmatched Precision and Accuracy

Frequency Standard
The Tycho GPS Frequency Reference provides the most precise and stable, GPS-synchronized, time & frequency outputs in the world.  The Tycho uses software algorithms that are the result of over 20 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.  Features include:
60-Day Money-Back Guarantee
  • A 1 PPS output with <20 nanoseconds RMS timing accuracy to GPS.  10-Nanosecond Calibration Option available.
  • A frequency accuracy better than 1x10-13.
  • An amplitude-modulated, user-selectable timecode output (IRIG-B, NASA-36, 2137).
  • A network port with SSH, Telnet, HTTPS (Web Interface), FTP, SNMP and more.
  • An RS-232 serial port.
  • Two-year warranty, free technical support and software upgrades for life.
  • Options: OCXO, Low Phase Noise Outputs, Telecom Outputs, 10 MPPS, Pulse Rates, Additional Time Code Outputs, Alarm, -48Vdc Input and more.
Web Interface
Sample Tycho Webpage
Status monitoring can be easily accomplished by pointing your web browser to the Tycho.  Here is an example of one of the status pages.  You can also perform software upgrades with the Web Interface.  For security-conscious users, HTTPS can be completely disabled.

Oscillator Option
The Tycho can be configured with a medium-stability, high-stability, or ultra-stable OCXO with SC-cut resonator.  Click here for datasheet.

Low Phase Noise (LPN) Output Option
This option provides four or eight isolated, 5 or 10 MHz, frequency output signals with exceptional spectral purity.  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 option module provides two or four outputs which can be any combination of E1, T1 or Composite Clock.  An alarm output is available as an additional option.  SSM is supported.  Click here for datasheet.

More Options
Several other output options are available.  Click here for datasheet.  These outputs, which provide additional flexibility in configuring your Meridian GPS Frequency Standard, are:
  • One, two, four or eight programmable pulse rate outputs.
  • Four or eight buffered analog timecode outputs.
  • A direct digital synthesizer (DDS).
  • An alarm output.
  • A second serial port with a once-per-second, on-time, serial timestring.
