Indeed the minimum required order. We are fortunate that there are some
larger vendors who have simplified that. Also ebay is good about small
counts but then they stick silly shipping costs on
Good luck

In 1974 the "39A Precision Oscillator" for the L5 Coax system
boasted a 14-bit DAC to set the frequency.
The article about it is quite interesting:

They spec sort-of-an-avar:
"This 5.12-MHz precision oscillator is characterize

As others have written, getti
If anybody knows how to do this, I bet it would be the people who do
long-baseline
interferometry at millimeter-wave frequencies, such as at the eVLA in New
Mexico.

You probably know that much better than I do, but I thought that

That is true. Is post-processing not an option here?

VLA and ALMA aren't exactly VLBI - they're all in the same (general)
place and they distribute LO and timing signals to all the antennas.
Larry D'Addario, recently retired from JPL and now down at Caltech,
described the setup at ALMA in 2009 - He's talking 1 microsecond, maybe
100 nanoseconds.
