PTS-SAASM Network Ready Precision Time System • GPS Disciplined Atomic Clock • Network Time Server • Dual Redundant Version Available • Complete Remote Network Control using Standard Web Browser • SA-ASM GPS Receiver • 10MHz, 1PPS IRIG B, Serial and Time Codes • Timing Accuracy < 40ns rms to UTC The PTS-SAASM 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-SAASM 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-SAASM 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. A low cost rack adapter is available (not shown). The PTS-SAASM utilizes a 12 channel P(Y) code SAASM GPS receiver. It may also be disciplined to an external 1PPS/HaveQuick time code source. A 100baseT 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-SAASM, 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 ultrastable, low phase noise frequency reference derived from an SC cut crystal that is locked to the rubidium reference. 1153 Warner Avenue ● Tustin, CA 92780 ● 714-755-1050 Phone ● 714-755-0175 Fax ● Toll Free 877-FOR-SYNC www.brandywinecomm.com info@brandywinecomm.com
