Software. Electronics. Personal Rants.
Recently I found a used HP/Agilent 53131A counter on Ebay and the offer was too good to pass on. It arrived in good condition and fully working, but it lacked an OCXO timebase and the built-in TCXO is not very stable.
I started looking around for OCXO options and while you can buy them on Ebay, most of them are quite expensive (more than US$200).
