I have two similar Symmetricom GPSDO boards but with a slightly different parts layout that were manufactured in about 2012. The OCXO in the first one is 4.1950 Mhz and there is a 10 Mhz VCO next to it.
The second one has a Symmetricom SA22-c Rb oscillator. The large blank spot in question is for the version of these that would have the Rubidium oscillator and the copper foil is part of the heat sink for that version. I haven’t checked the output frequency of the SA22-c but it is probably the same as the OCXO version. -Arthur _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
