In my case, a GPS disciplined oscillator. There are a number of these
floating around on eBay. The one I selected is the Trimble
Thunderbolt, because I know one of the firmware engineers that worked
on it. There is also a FB program called, "Lady Heather's Disciplined
Oscillator Control Program" which allows you to monitor the
Thunderbolt's operation. Trimble also has a program posted on their
website, used for Thunderbolt configuration/set up, and status
monitoring.

Re: GPD 10 MHZ Reference

Make sure the HP's output signal level is about right (~12.5 dBm, I think...) before using it. If it's a square wave output at 5V/0V, you're supposed to add a series resistor. I think this is all in the K3EXREF manual.
