Hacking the HP5065A Rubidium Frequency Standard¶
I ran into a cheap used HP5065A on eBay.
There are a lot of indications that the physics package in the HP5065A has more potential than the electronics.
And since I recently bought the 3rd edition of The Art Of Electronics, which is all about quality electronics, I suddenly had a new project...
The articles below are in reverse chronological order, if you want to follow the saga, start from the botton.
Note on 20170304: This project is neither dead nor pining for the fiords, but we are busy building a house and my time is very limited. I expect to continue in the autumn 2017.
