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

[Robert LaJeunesse]

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.
