I have a 100MHz scope, DVM, frequency counter, signal generator, etc.
Sorry, no spec an. I wish I had one.

The first problem is that it fails the first performance test. Instead
of 100nS, I get about 10nS and that slowly increases to about 12nS.
This is with the unit already warmed up and it is repeatable. I
checked the internal reference output and it is very close to 10MHz,
so that isn't the problem.

Before I go any further, I think I'll open it up reseat all the
boards. It couldn't hurt.
