Hi,
I need a high quality RF signal source, for example from OCXO or RF
signal generator.
But I need to know, what is a fractional frequency instability
measured during 1s period. One can find information about SSB phase
noise spectra in datasheets, but how to convert this numbers to
frequency instability?
In RF signal generator I can set requested frequency on a display. But
how stable generated signal is? Can I expect that generated frequency
will change about 1e-8 or maybe 1e-12 during 1s?
Of course, this depends on the internal reference and phase loops
inside the box, but such a data should be published in datasheets.
From SSB phase noise spectra one can obtain time jitter, but it is
possible to convert this value to frequency deviation?
thanks,
E.C.
