The typical test supply on a bench for clean VCO testing is a small gel cell battery. For a regulated power supply, make one using a 723. The 723 has far lower noise out than the monolithic regulators.

I know this topic has been discussed in the past on the list, but a colleague is asking if there are any off the shelf low noise power supplies for testing oscillators. Something a cut above an HP "brick" lab power supply etc. They are hoping to avoid having to homebrew a power conditioning circuit. Did we ever arrive at a concensus as to the state of the art in homebrew power conditioning circuits? Any help would be appreciated.
