Lucent/Symmetricom RFTGm-II-Rb/RFTGm-II-XO Rubidium & GPS Frequency Standard 1

Description: This auction is for a Lucent (Symmetricom/Datum) Dual Frequency Standard with one RFTGm-II-Rb LPRO based Rubidium Module and one RFTGm-II-XO GPS Disciplined Low Phase Noise Quartz Oscillator . This system is in excellent physical and electrical condition - after years in storage the RB rubidium module locked quickly, and the XO Quartz unit containing the GPS module locked in about an hour. In this system the rubidium module syncs to the GPS 1PPS signal from the GPS in the XO module and locked shortly after. Please refer to the listing photos which show both units operating normally. Some photos show the default Rb unit Online (locked) and other photos with the Rb interface cable disconnected forcing the OX unit Online (GPS unit locked). Feel free to contact me with any questions. Included: One - RFTGm-II-Rb KS-24019 L108 CC 407921329 module is based on an internal 10MHz LPRO Rubidium Oscillator. The RFTGm-II-Rd has two 10MHz outputs and one 15MHz output. One - RFTGm-II-XO KS-24019 L109 407921337 module is based on an Oncore GPS disciplined 10MHz Low Phase Noise Quartz.The RFTGm-II-XO has one 10MHz input and one 15MHz output. One - Symmetricom VIC100 26dB GPS Antenna. All factory interconnect cables. An aftermarket power supply. With the included supply the system is "Plug & Play". I used a DB-15 breakout connector for the power supply that plugs directly into the factory harness so other system functions could be accessed. These Lucent systems are popular because they are based on 10 MHz oscillators and most purchasers would prefer all 10MHz outputs. In response after market user have posted a number of articles on the internet detailing various ways to remove/modify the internal electronics to convert the 15MHz to 10MHz.Also since the RFG-M-RB and RFG-M-XO use the same board an additional 10MHz output can be added to the XO unit by simply populating the circuit board to match the output on the RB version.Another interesting option I recommend upgrading the original GPS module with a Synergy SSR-VP/UT+ module which Synergy offers a "drop-in" replacement based on a UBLOX GNSS chip. I tested one and it offered faster lock, more sensitivity in weak signal areas, and potentially some minor performance increase. So although there is not much Lucent Systems manufacturer information on these there are a number other online resources documenting modifications on these and other similar variants such as the RFTGm-II-Rb providing details on modifying them into great low phase noise 10MHz bench frequency standards. And of course if I can be of any assistance such as information on this specific unit please feel free to contact me.
