GPS-8 Plus Full-featured GPS Time & Frequency unit with front-panel keypad and display - 1

GPS 8 PLUS GPS SYNCHRONIZED TIME AND FREQUENCY STANDARD Frequency Accuracy of 1x10-12 Choice of Disciplined Oscillator Very Stable Time & Frequency outputs Front Panel Display & Keypad 1U 19" rack mount Timing Accuracy 40ns, rms to UTC 1PPS and IRIG B Time Code outputs Two Serial Ports 1 MHz, 5 MHz or 10 MHz sine waves 1.544, 2.048 or 19.6608 MHz outputs The GPS is an economical and reliable Time and Frequency instrument offering a wide range of standard features in a compact, IU rack-mount chassis. Precision time and frequency outputs, accurate to 40 nanoseconds to UTC/USNO and 1x10-12 respectively, are provided in a variety of signal formats. Two serial data ports, RS-422 and RS-232 are provided. Time, date, position, GPS satellite health and signal strength are reported. Applications for the popular GPS8 include central time and frequency systems, timing for power utility systems, and frequency standards for a wide variety of communications installations. The IRIG B output is perfect for use in range timing installations, as inputs to SER and SCADA systems and for driving remote time displays. 1PPM and 1PPD or IRIG B DC shift may be selected for output. The serial time code output (IRIG B is standard) allows time synchronization to be distributed to computers, displays, and other equipment requiring precise time. A variety of internal oscillators, including the standard TCXO, provide price/performance trade-off possibilities for the user. The GPS 8 can be specified to include an oscillator that is appropriate for almost any application. An advanced oscillator control algorithm precisely disciplines the internal oscillator to the GPS input ensuring superior holdover performance. In addition to the standard TCXO, a variety of oven controlled (OCXO) and Rubidium oscillators are optionally available. A precision 1PPS time mark output may be used for synchronizing or calibrating other equipment. Two square waves, 1.544, 2.048 or 19.6608 MHz, and an 8 kPPS frame rate enable the GPS 8 to be used as a telecommunications primary reference clock (PRC). Sine waves of 1, 5 or 10 MHz are also available. The sine wave outputs are configured as two pairs of two of the above frequencies. Signal level integrity monitoring is provided for the sine wave outputs. Status information is provided over the serial interface, by a summary alarm, and by four front panel LED indicators. The status reported by the summary alarm and the serial interface includes loss of GPS signal, PLL unlock, loss of output, and Rubidium oscillator unlock. (The rubidium oscillator is an optional feature) 1153 Warner Ave. ● Tustin, CA 92780 ● 714-755-1050 phone ● 714-755-0175 fax • Toll free 877-FOR-SYNC www.brandywinecomm.com info@brandywinecomm.com
