GPStarplus® Model 565
GPStarplus® offers a new level of price-performance in off-the-shelf Time/Frequency Systems. Full-featured, but compact (1.75″ high mountable in a standard 19″ rack), the GPStarplus provides accurate synchronization to UTC, including IRIG-formatted outputs. Operation interface and control are provided by RS-232 or front-panel keypad.

PRODUCT DESCRIPTION
GPStarplus® is a fully featured, off-the-shelf, compact time and frequency system providing a new level of price/performance. It provides accuracy within 100 nanoseconds of UTC (Coordinated Universal Time). GPStarplus tracks up to eight satellites at a time. When used as a frequency standard, GPStarplus can provide 5 E-12 frequency accuracy.
GPStarplus® is packaged in a 19″ rack mount chassis that is only 1.75″ high. The control and operation interface is provided via RS-232 or a front panel key pad. A 2-line by 40-character backlit LCD display reports Julian time and date, as well as informing the user if time is locked, how many satellites are being received, and other status information.
The standard power supply operates from 95 – 264 VAC at 50 – 60 Hz.
