Hello to the group,
Have you ever used frequency/phase data to estimate phase noise of your O's
using Stable32? I probably do something wrong in conversions when using Power
button because my plot starts on 10e-7 Hz and ends on 10e0 Hz

Hi
The CSAC spec sheet calls out an aging rate of 0.9 ppb per month as
“typical”. There is also a temperature spec of 0.4 ppb. If both are correct
for your sample (*and* aging is linear ) you would be out by roughly 10 ppb
per year. There also is a voltage stability spec that might be impacted
Jim:
One around 1s/y, one 6 s/y and one 11 s/y. I was looking to do
better than 1 s/100 years, but that was for the CSAC.

1 second/year is quite good - about 30 ppb. It's a bit tricky (like all
things time-nutty) - the "aging" on a TCXO could be that good - but the
I do not have great equipment to do the measurement but it is at least this
good at 10 MHz as measured on one of my 8642As. I can't measure phase noise
at 30 or 100 MHz.
