Phase noise is (usually) more important than absolute frequency accuracy. I suggest some kind of low phase noise master oscillator (OCXO) feeding a DDS without an internal multiplier.
If internal multiplier in DDS, that, rather than the frequency reference source will set the phase noise floor of the sampling. --- Graham == On Wed, Apr 11, 2018 at 11:00 AM, Jerry Hancock <je...@hanler.com> wrote: > For and RSP?
