TimeLink microsystems Source 4 output TMF1211 is designed for applications requiring an accurate 10 MHz source reference and a distribution signal on 4 outputs. The equipment is as a standard to the housing 19 "height 1 U. It is powered by VAC with a large range in voltage and frequency. Oscillator The 10 MHz pilot is a thermostatic crystal oscillator (OCXO) of high stability and having excellent phase noise performance. The frequency of the driver is adjustable by a multi-turn potentiometer accessible from the front face of the drawer. Frequency outputs The driver outputs a level is distributed to the four output amplifiers. Frequency outputs are equipped with a passive bandpass filter and an isolation transformer. Each output has a separate amplifier to improve noise rejection injected onto a release. The output signal is adjustable from 0 to 13 dBm at a load of 50 Q. The setting is common to all outputs and it is done in factory. Output BNC connectors are insulated from the mechanical ground. Monitoring A local monitoring (alarm light) and remote (dry contact) is available on the equipment.
