Tempus LX GPS Network Time Server
Our Full-Featured GPS Time Server
Provides Accurate and Reliable Network Time Inside Your Firewall
|
|
The Tempus LX is a full-featured, high-performance, Stratum 1 Time Server. This model
uses GPS as its time-synchronization source and it will
deliver accurate and reliable time throughout any system running an NTP or SNTP client.
- Supports 200,000 network clients with <10 microsecond NTP timestamp accuracy.
- Extended Stratum 1 operation if GPS signal is lost.
- User-friendly display & keypad with built-in help menus.
- NTP, SNTP, MD5, SNMP, SSH, SCP, TIME, DAYTIME, TELNET, FTP, DHCP and more.
- IPv4 and IPv6 compliant.
- Superior reliability - an MTBF of 25 years based on demonstrated field data.
- Options: Oscillator Upgrades, Alarm, Timecode, Pulse Rates, Sysplex, -48Vdc.
Easy to Install and Maintain
Installation is done in just a few minutes using
either DHCP or by configuring the unit with a few simple keystrokes on the front-panel keypad/display.
Monitoring, maintenance and control is easily and securely accomplished via a
wide range of protocols including SNMP v3, SSH, and RS-232.
Network Security Hardened
Extra care has been taken with the Tempus LX to "harden" it against network attacks.
There are only a small handful of settings that need to be made and they typically
need to be set only once in the lifetime of the product. Since this is a set-it-and-forget-it
box we have eliminated all extraneous protocols/services in order to minimize exposure to security
holes. You can change critical settings over the network using SSH or Telnet and monitor the
alarm/status information by using SSH, Telnet, or SNMP. Security-conscious
users can disable any or all of the risky protocols such as Telnet, Time and Daytime or restrict
access to SSH, Telnet and SNMP to specific hosts.
Extended Stratum 1 Operation if GPS Signal Lost
If your GPS antenna is on the roof the
signal can be lost for several reasons, such as lightning strikes and damage
due to maintenance activities or vandalism. For window-mount antennas the signal is often missing
because of poor sky visibility. The Tempus LX will continue to serve Stratum 1
time for a substantial period if the GPS reference signal is ever lost. This is
called the holdover period and it is dependent upon the quality of the oscillator and the quality of the
software control algorithms.
The standard Tempus LX is provided with a TCXO. If the GPS signal is lost it will drift away from
perfect at the rate of 10 milliseconds during the first day.
This is the best
holdover performance of any time server on the market with a TCXO. For even
better holdover performance you may want to consider an oscillator upgrade. Oscillator
drift rates and Stratum 1 holdover periods are listed below:
|
| TCXO |
10 milliseconds for 1st day |
24 hours |
| OCXO |
100 microseconds for 1st day |
35 days |
| Rubidium |
8 microseconds for 1st day |
140 days |

Best Window-Mount Antenna Performance
Our GPS time servers have the ability to operate in a single-satellite mode. This
lets you avoid the trouble and expense of a rooftop installation by allowing you to mount the antenna
in a window of your building up to 150 feet away. And with our best-on-the-market holdover
performance - your antenna only needs to see one satellite once a day to continue
serving accurate Stratum 1 time to your network. Read about our other
GPS Time Server.
Your Satisfaction Is Guaranteed
The Tempus LX is backed by a full 60-Day Money-Back Guarantee, a 3-Year Parts and Labor Warranty, and
free technical support and software upgrades for life.
