Is the MV89 the best OCXO to use as a reference? I notice there is a
place selling them for $19.99 buy it now price otis the $30 deal
I want to get setup for frequency stability measurements. I have a
t-bolt but being conservative (when it comes to engineering) I'd like
a second non-related standard and a good ocxo should work for that
over medium term tau. (I think)I don't know how the various $20 to $30
OCXOs compare. And I don't yet have means to compare them.
