I'm interested to know, from anyone who actually has this device in
production, how you are doing frequency setting.

I'm thinking in terms of a counter driven by IEEE488, and some sort of
automated process to tweak the on-chip cap values to dial in the
oscillator.
It's not clear to me whether it is better to measure the 16 MHz test
pin, or the RF carrier, or both.

Achieving 10ppm accuracy out the door is the end goal.
