Hi,
I have had the occasion recently to measure the aging and short term
stability of a bunch of oscillators.
Measurements were against an EFOS-2 Hydrogen Maser.
I thought that the results between 10811A (-60109 variant) and the
10811-60111 might be of interest to some.
All oscillators had aging below 5X10-10/day.
As you can see the short term stability of the -60111 compares favorably
with the 10811A.
I'll be making some measurements on the -60158 variants and some motorola
units soon.
Cheers!
