Mooneer,
I would not go so far as to say that. Any stable signal generator needs
some warmup time. For instance my HP8640B is very stable - but only
after about a 2 hour warmup period. Everything inside has to come up to
operating temperature, and it drifts until that occurs.
I would suggest at least a 15 minute warmup for the XG50, a half hour
would be better. At least I would be more comfortable with an
assumption like that even if it is overkill.
I believe the 8 hour 'burn in' is a time to allow the XG50 crystal some
'run time'. New crystals will typically exhibit some initial change in
frequency that does not re-occur - think of it similar to the 'break-in'
period for a new engine - you don't have to repeat that every time you
start the car, but you do have to let it warm up before it will deliver
peak performance.
73,

Assuming the 8 hour run has been done, it sounds like I can turn on the
XG50 right when I start the procedure. Thanks for the clarification. :)
