[time-nuts] Trimble Thunderbolt, any easy way to create 500 MHz reference from one?

Sorry to say the 6130A is an "all on one board" design. Not really suitable for
extracting the multipliers.
Shameless UN-plug: Another time-nutter has already taken the 6130A I was going
to have at Dayton.

Bob's suggestion to get a Ballantine 6130A Time Mark Gen might be your easiest
solution if this is a one-off project. According to the schematic, the 10MHz
oscillator is sent through a series of multipliers and filters to arrive at the
500MHz High Freq output. Specifically, it goes through a doubler and two
quintuplers.
I don't know how the unit is constructed (I only have a schematic, not the
complete manual), but if the RF circuitry and the digital dividers are on
separate boards, then you might be able to use just the RF board to construct
your 500MHz signal. (I'm assuming that your intent is to construct the project
into a single enclosure).
The only other solution that might be easier would be to find a PLL board that
can be programmed to output your 500MHz signal. I looked over eBay and Google
without much luck there.
Good luck with your project.
