I have a dilemma and wish to access the collective wisdom of the group to advise a solution.
I am building a clock generator based on a Thunderbolt. I have an LPRO and would also locate this in the same enclosure. I will also add a distribution amp and a divide chain in due course. The ultimate purpose of the set up is to provide a self contained clock generator set for my other test equipment, and also an experimental workstation for Rubidium and GPS disciplined experiments. Most of my other equipment is for 19-inch rack mounting. I have two potential solutions for housing the timing kit: 1. An old dismantled HP 4U scope chassis which will fit in with my other equipment physically, and can be racked if necessary. The PSU would have to be built into the same enclosure. 2. A pair of Anritsu instrument cases which once house a bit error test set. The two units clip together beautifully, and are free standing. As there are two units, this solution would allow me to build the PSUs in one case and the more sensitive timing electronics in the other. These units cannot be racked on account of their form factors. Both solutions will require me to do some bespoke metalwork, but that is no problem for me and amounts to about the same amount of work for either solution. So what does the group advise? Is it vitally important to keep PSU components isolated from the timing electronics? I want to create the least noisy clock source given the components I have. Looking forward to hearing some opinions...
