Hi Dave, That's exactly the approach I'm going to use. Outputs that go to instruments that might see the low noise and then outputs that go to devices that aren't phase noise sensitive like counters, scopes, pulse generators and others.

One thing that came to my mind, is that there may be some point in having one or two outputs where more money is spent. Then if one thinks an item might be particularly sensitive to some aspect of the reference, one can use that. One could for example have one or two outputs which have harmonics suppressed 100 dB, without going to unnecessary expensive on all outputs.
