TimeLinkmicrosystems TMG5000 GNSS disciplined T/F generator with 8 x programmable outputs The TMG5000 is a GNSS disciplined time & frequency generator specifically designed for applications requiring different type of time & frequency signals on the same unit. The 8 independent outputs are programmable in order to get IRIGB, 1PPS, or 10 MHz on each output. The equipment is housed in 1U 19" standard rack. GNSS signal is used for long term disciplining of the internal oscillator. GNSS The internal GNSS receiver is a specific receiver dedicated to time application. It's a bi-constellation model able to acquire both GPS and GLONASS satellites simultaneously. It delivers a very high precision UTC second reference pulse. Irig-B generator The equipment includes a IRIG time code generator that allows to provide: • An IRIGB12x signal (amplitude modulated analog signal) on both outputs. • An unmodulated signal IRIGB00x (DCLS) on a RS485 serial link. These signals are in phase with the internal 1PPS equipment itself synchronized on the 1PPS of GNSS reference. Oscillator An internal OCXO type oscillator provides a 10 MHz frequency used to maintain time. The stability of this oscillator is better than 1x10-9 per day in case of loss of external time sourcing. When disciplined by the GNSS, the long term stability remains better than 5x10-11. NTP Service The TMG5000 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 to 10 ms. 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: ■ The SNMP standard protocol (MIB provided) ■ A proprietary UDP or TCP protocol Configuration The overall configuration of the unit is stored on a removable SDCARD memory which allows remote software update easily.
