It just so happen that I also have an HP 5334B, which I bought when I had given up on getting an HP5370 for a *reasonable* cost, considering my application. It draws 20 VA instead of 200, but this one does not have the 10811 time base. This will also be a lot easier on the UPS, as we do loose power here somewhat regularly (but not for long, unless a hurricane is involved) during the stormy season.
Thanks for another great suggestion.
