PTS Network Ready Precision Time System

The PTS is a state of the art frequency instrument offering a wide range of features and time and frequency outputs accurate to <40ns rms to UTC(USNO) and 1x10-12 respectively. GPS Disciplined Atomic Clock Full Remote Network Control Using Standard Web Browser Optional SA-ASM GPS Receiver Timing Accuracy <40ns rms to UTC NTP Network Time Server Dual redundant system in 19 Inch rack mount Low Cost10MHz, 1PPS, IRIG B, serial and BCD time code outputs The PTS is a state of the art frequency instrument offering a wide range of features and time and frequency outputs accurate to <40ns rms to UTC (USNO) and 1x10-12 respectively. This new generation of network appliance is economical and reliable and offers complete remote control and monitoring via a web-browser based interface. The PTS can be used in either a single or dual redundant configuration and in conjunction with one of Brandywine Communications range of Distribution Amplifiers, such as the FTSU-100. Applications for the popular PTS include central time and frequency systems, satellite earth stations, military communication systems, and high availability network time servers. An extremely accurate internal Rubidium oscillator is used as the internal time base that drives all the time and frequency outputs. This Rubidium oscillator is disciplined using an advanced control algorithm, ensuring superior holdover performance. The time constants of this algorithm are user-adjustable to suit specific applications. The PTS is available both with standard C/A code and optional P(Y) code SA-ASM GPS receiver. It may also be disciplined to an external 1PPS/HaveQuick time code source. A 10baseT Ethernet port is provided which is used both for monitoring and control of the instrument and for Network Time Protocol. This interface supports both fixed and dynamic IP address assignment via DHCP. In addition to configuring the PTS, the built-in web browser provides information on GPS, internal monitoring of time errors, and internal parameters of the atomic oscillator. The user may set thresholds of any monitored parameter to trigger an alarm. A precision 1PPS time mark is available for synchronizing or calibrating other equipment and the IRIG B serial time code allows synchronization to be distributed to other computers, displays and related equipment requiring precise time. An ASCII serial port outputs any user-selected time of day message at a 1/sec rate for synchronizing other equipment. The same output port may also be configured to output 50 bit/sec BCD time code in accordance with ICD-GPS-060. A high stability 10MHz sine wave output provides an ultra-stable, low phase noise frequency reference derived from an SC cut crystal that is locked to the rubidium reference.
