TRAK Microwave has added a GPS time and frequency clock to its product offerings. The 50-channel 8835 GPS reference clock serves satcom, defense and wireless applications. The 8835 GPS clock has extreme power and interoperability options while maintaining GPS accuracy and reliability, TRAK Microwave said. While tracking GPS, the clock exhibits a frequency accuracy of -12 and a 1 PPS accuracy with 8835 GPS Clock by TRAK Microwave. The proprietary oscillator steering discipline algorithm can enhance the RMS accuracy of either the double oven crystal oscillator or optional enhanced rubidium oscillator for greater depths of accuracy. To increase interoperability, the 8835’s 10/100 base-T Ethernet interface can leverage a range of network protocols including NTP, SNMP, Telnet, SSH and FTP for status and control. The unit can also accept a variety of power sources including 24 VDC, 48 VDC or 100-240 VAC with an external AC/DC converter. The highly compact and configurable device operates from -30oC to +60oC with a TNC GPS receiver port. A datasheet on the 8835 can be downloaded here.
