Before I go and spend $150 on eBay for one - I would like to know if they can be used as a stand-alone GPS desciplined oscillator without the 10mhz input from the rubidium unit.
Also - has anybody found a manual on-line for one of these guys? 73 - Tom in St. Louis There was an older posting from Oct 2005 describing the RFG-M unit: The board you are describing is used in the Lucent RFG-M-XO reference frequency generator. It takes in 10 MHz on J2 from a Rubidium oscillator and disciplines the Efratom SC cut OCXO on the main board from the 10 MHz input. The output from the OCXO is converted to 15 MHz and supplied as the reference output on J4. The RFG-M-RB and RFG-M-XO normally mount together in a chassis (which I didn 't get) and the modules are connected to the chassis by a harness with a DB15 on the chassis end. The pin out for the harness is as follows: DB15M TO/Pin# Description Pin # 1 RFG0 - P1-1 +24v 1.3A/0.6A 2 RFG0 - P1-2 Common 3 RFG1 - P1-1 +24v 0.6A/0.4A 4 RFG1 - P1-2 Common 10 RFG0 - J3-1 Alarm 11 RFG0 - J3-2 Alarm 12 RFG1 - J3-1 Alarm 13 RFG1 - J3-2 Alarm A second interface cable ties the RB to the XO as follows: RBJ5 XOJ5 Pin # Pin# 1 5 3 3 The male DB9 is P1 and pin 1 = +24v @ 400ma, Pin 2 = Common. This will power up the board so you can verify operation of the OCXO. Unfortunately that is all the information I have on the unit. Hope this helps. ____________________________________________________________________________________Give spam the boot. Take control with tough spam protection in the all-new Yahoo!
