Since this is time nuts ADEV is sacred, but the question is the use case.
Are we looking at a time nuts level frequency distribution network. Or are we trying to lock benchtop instruments with poor internal standards to a common ‘Good’ reference. If the former it can be done but will require a fair amount of design work as well as some EMC Modeling of the system to ensure no feed through of unwanted signals and/or modulation or beat products If the latter simple detection and switching will be sufficient but dual switch much better.
