They're shipping them.. I got quoted a 12 week delivery in April, $9k
for the box, about $12k-15k for the software, although

HI
It sort of depends on what offset frequency you are looking at. If you are
after very wide band stuff at very low levels,
the notch filter / spectrum analyzer approach has always been a good one. You
may or may not need a low noise
amp after the notch depending on the analyzer. Your notch

The Symmetricom Time Pod is pretty much the lowest cost commercial / newl “low
phase noise” measurement instrument. You can find all sorts
of older stuff on auction sites in who knows what shape. The HP 3048 is the
granddaddy of them all.

I was looking at some high end commercial low noise oscillators and see
they use instrument like the Agilent E5052B signal source analyzer for
phase noise measurements. When I looked for them on eBay, it soon because
apparently they were very expensive.
Then I see this oscillator that locks to
