Yes I have a Trimble Thunderbolt. Two actually.
Some of these counters are impressive pieces of work.

Nice counter, with GPIB.

And no fans in the 5334, so quiet.

Lots. HP does not seem to take acoustic noise level in to consideration
in its designs.

I was recently able to pick up a nice HP5335 with a 10811 oscilator and
enhanced GPIB board for <$100.00 from the usual auction site.

My first thought was to use a bunch of tvb's picPETs backwards. :) Feed
them all the same PPS and clock each one with one of the clocks you want to
test. But that requires a serial port per XO. Maybe you have an old
many-input serial box in the junk bin, but I'm always short of them.

If you can find an HP 5316B at the right price it would meet your basic needs.
Takes 1, 5, or 10 MHz for external reference (has 10MHz out). The A and B
channels are 100MHz rated, optional C channel is 1GHz. The optional TCXO (or
OCXO) is likely not needed in your case. GPIB might prove handy. I
