Meridian Precision GPS Frequency Standard
Our Top-of-the-Line GPS Frequency Standard
For Unmatched Precision and Accuracy
|
|
|
The Meridian Precision GPS TimeBase is a full-featured frequency standard that provides the most precise and stable,
GPS-synchronized, time & frequency outputs in the world. The Meridian 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. The modular, solid state design yields a conservative
MTBF of 25 years and accepts a wide range of
field-installable options.
- A 1 PPS output with <10 nanoseconds RMS timing accuracy to GPS.
- A frequency accuracy better than 1x10-13.
- A plug-and-play design that accepts up to 5 option boards in a single 1U chassis.
- A network port with NTP, SNMP, SSH, Telnet, FTP, Enterprise MIB and more.
- A user-friendly display & keypad with built-in help menus.
- An amplitude-modulated, user-selectable timecode output (IRIG-B, NASA-36, 2137).
- An RS-232 serial port.
- Two-year warranty, free technical support and software upgrades for life.
Oscillator Options
The Meridian Frequency Standard 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. A mid-range, high-stability OCXO with SC-cut resonator provides
excellent phase noise, temperature stability and ageing. Click here for datasheet.
Low Phase Noise Output Option
This option provides up to 20 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.
Programmable Digital Output Option
This option adds four independently programmable outputs to your Meridian Frequency Standard.
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, including 1.544
MPPS and 2.048 MPPS. The synthesized rates are phase locked to the system
oscillator. Click here for
datasheet.
Analog Timecode Amplifier Option
This module provides four time code outputs. The
user-selectable format can be one of either IRIG-B122, IRIG-B123, IRIG-B
IEEE-1344 compliant, NASA-36, or 2137.

More Options
The Meridian supports several output options via two additional BNC connectors
installed on the CPU module.
Click here for datasheet. These outputs, which
provide additional flexibility in configuring your Meridian GPS Frequency Standard, are:
- One or two programmable TTL outputs.
- A direct digital synthesizer (DDS).
- An alarm output.
- A second serial port with a once-per-second, on-time, serial timestring.
