In a previous post I briefly talked about a 6GHz (002, 006, 010, 011) HP8753D that I had recently purchased on eBay. And along the way I had also acquired all of the other bits and pieces (mainly from Eric Haskell in Texas) to turn an 011 unit into a non-011 (with integrated test set) unit. Well, it's finally done - fully cal'd and ready to go! The hardware conversion only took a couple of hours. The full cal took longer.
