Array ( [system] => TrueTime XL-DC [id] => 3110 [summary] => The ultraprecise XL-DC provides the highest degree of time and frequency accuracy available in a GPS timing receiver:
* Less than 40 nanoseconds rms accuracy to UTC during Selective Availability (SA)*
* Better than 1x10-12 frequency accuracy
* Versatile and modular architecture
* Supports many different output options
* Receiver Autonomous Integrity Monitoring (RAIM)
* 1 PPS output
* IRIG B time code output
* Internet/local network remote control option

The ultraprecise XL-DC provides the highest degree of time and frequency accuracy available in a GPS timing receiver. Standard outputs include a 1 PPS, analog IRIG B time code and serial I/O time strings. A major advantage of the XL-DC is its versatile and modular architecture. A wide range of time and frequency plug-in options allow the XL-DC to be customized for specific applications and easily upgraded at a later time.

TrueTime's proprietary multisatellite ensembling techniques and RAIM provide very stable and precise timing outputs. Timing accuracy is less than 40 nanoseconds rms to UTC even during Selective Availability (SA). This superior oscillator disciplining to GPS enables internal oscillator accuracy to better than 1x10-12. For applications requiring increased oscillator stability, the XL-DC can be upgraded to ovenized quartz or rubidium oscillators.

The XL-DC is available in three base configurations to meet varying requirements for keypad control and information displays. RS-232 control is standard on all units. Using the keypad or RS-232 port, users have control over a variety of time formats, configurations, and output options, including GPS and oscillator status and controls.

The highly modular backplane architecture supports multiple time and frequency output options to address specific needs. These plug-in output modules can be incorporated at any time and significantly increase the adaptability of the clock to changing application requirements. See the Options section for a list of currently supported options. The base models support up to four single-height plug-in modules. Using the optional 3.5" high chassis, it can accommodate up to ten single-height modules.

Remote control over the Internet or local network is easy using TrueTime's Telnet network interface plug-in option. Using Telnet, users can remotely check the status and/or configure the XL-DC. Most operations possible via the RS-232 port are also possible via Telnet. The network interface option supports DHCP so that no user intervention is required for the XL-DC to be network ready. Password protection is provided to maintain secure access to the unit.

THE ULTRAPRECISE XL-DC PROVIDES THE HIGHEST DEGREE OF TIME AND FREQUENCY ACCURACY AVAILABLE IN A GPS TIMING RECEIVER. STANDARD OUTPUTS INCLUDE A 1 PPS, ANALOG IRIG B TIME CODE AND SERIAL I/O TIME STRINGS. A MAJOR ADVANTAGE OF THE XL-DC IS ITS VERSATILE AND MODULAR ARCHITECTURE. A WIDE RANGE OF TIME AND FREQUENCY PLUG-IN OPTIONS ALLOW THE XL-DC TO BE CUSTOMIZED FOR SPECIFIC APPLICATIONS AND EASILY UPGRADED AT A LATER TIME. TRUETIME'S PROPRIETARY MULTISATELLITE ENSEMBLING TECHNIQUES AND RAIM PROVIDE VERY STABLE AND PRECISE TIMING OUTPUTS. TIMING ACCURACY IS LESS THAN 40 NANOSECONDS RMS TO UTC EVEN DURING SELECTIVE AVAILABILITY (SA). THIS SUPERIOR OSCILLATOR DISCIPLINING TO GPS ENABLES INTERNAL OSCILLATOR ACCURACY TO BETTER THAN 1X10-12. FOR APPLICATIONS REQUIRING INCREASED OSCILLATOR STABILITY, THE XL-DC CAN BE UPGRADED TO OVENIZED QUARTZ OR RUBIDIUM OSCILLATORS. THE XL-DC IS AVAILABLE IN THREE BASE CONFIGURATIONS TO MEET VARYING REQUIREMENTS FOR KEYPAD CONTROL AND INFORMATION DISPLAYS. RS-232 CONTROL IS STANDARD ON ALL UNITS. USING THE KEYPAD OR RS-232 PORT, USERS HAVE CONTROL OVER A VARIETY OF TIME FORMATS, CONFIGURATIONS, AND OUTPUT OPTIONS, INCLUDING GPS AND OSCILLATOR STATUS AND CONTROLS. THE HIGHLY MODULAR BACKPLANE ARCHITECTURE SUPPORTS MULTIPLE TIME AND FREQUENCY OUTPUT OPTIONS TO ADDRESS SPECIFIC NEEDS. THESE PLUG-IN OUTPUT MODULES CAN BE INCORPORATED AT ANY TIME AND SIGNIFICANTLY INCREASE THE ADAPTABILITY OF THE CLOCK TO CHANGING APPLICATION REQUIREMENTS. SEE THE OPTIONS SECTION FOR A LIST OF CURRENTLY SUPPORTED OPTIONS. THE BASE MODELS SUPPORT UP TO FOUR SINGLE-HEIGHT PLUG-IN MODULES. USING THE OPTIONAL 3.5" HIGH CHASSIS, IT CAN ACCOMMODATE UP TO TEN SINGLE-HEIGHT MODULES. REMOTE CONTROL OVER THE INTERNET OR LOCAL NETWORK IS EASY USING TRUETIME'S TELNET NETWORK INTERFACE PLUG-IN OPTION. USING TELNET, USERS CAN REMOTELY CHECK THE STATUS AND/OR CONFIGURE THE XL-DC. MOST OPERATIONS POSSIBLE VIA THE RS-232 PORT ARE ALSO POSSIBLE VIA TELNET. THE NETWORK INTERFACE OPTION SUPPORTS DHCP SO THAT NO USER INTERVENTION IS REQUIRED FOR THE XL-DC TO BE NETWORK READY. PASSWORD PROTECTION IS PROVIDED TO MAINTAIN SECURE ACCESS TO THE UNIT.
