TimeLinkmicrosystems TMG1200 GNSS and IRIGB table disciplined time & frequency generator The TMG1200 is a GNSS/IRIGB disciplined time & frequency generator designed for a wide range of applications. The equipment is (soused in a table (sox. GNSS/IRIGB signal is used for long term disciplining of the internal oscillator. GNSS synchronization The internal GNSS receiver is a specific receiver dedicated to time application. It's a bi-constellation model able to acquireboth GPS and GLONASS satellites simultaneously. It delivers a very high precision UTC second reference pulse. IRIGB synchronization The input IRIGB signal is an amplitude modulated analog signal (B12X code) GNSS synchronization is selected first because of its better Song term stability. Oscillator Oscillateur 10 MHz 1 ppm When disciplined by the GNSS, the long term stability remains better than txta9. NTP Service The TMG1200 includes a time service implementing standard NTP protocol (Network Time Protocol) allowing any computer or equipment linked to. the network to synchronize. Customer's computers can be synchronized with an accuracy of 1 to10ms. NTP client software must be installed on each client for its synchronization with the server. Remote control The remote control of the equipment is done via the network, using an internal web server Configuration The overall configuration of the unit is stored on a removable SDCARD memory which allows remote software update easily. IRIG-B generator The equipment includes an IRIG time code generator that allows providing an IRIGB122 signal (amplitude modulated analog signal) and an IRIGB002 (DCLS) over RS422. Those signals are in phase with the internal 1PPS equipment itself synchronized on the 1PPS of GNSS reference. Information contained in this document is subject to changes without further notice.
