Catalog excerpts

Features: • Ultra-stable GPS Disciplined Timing Reference • 5 buffered IRIG outputs • 5 buffered 1PPS outputs • 10MHz frequency reference out • 1U chassis 12 • Timing accuracy to 1 x 10 • Dual Port NTP Server The TRU is a state of the art, high-precision time/frequency standard capable of outputting five isolated IRIG Time of Day and 1PPS reference outputs. The TRU uses an internal GPS receiver to control a precision oscillator with accuracy up to 1 x 10-12 and excellent short term stability. The TRU incorporates a high-sensitivity 12 channel SAASM GPS receiver, incorporating the latest advances in GPS anti-spoofing technology. Dual Ethernet ports are used for both monitoring/control of the FRU using Simple Network Monitoring Protocol (SNMP) as well as providing Network Time Protocol (NTP) to clients. A Brandywine supplied user application may also be used to provide a Graphical User Interface to the TRU. The TRU is available is a number of configurations to support specific applications. A Mobile Application version features a special vibration isolated oscillator that provides isolation of the reference source from portable generator induced phase noise. The High Performance version uses a rubidium oscillator. A C/A code GPS receiver is available for non-military applications.
