Evening relaxation on the Rohde & Schwarz Vector Network Analyzer ZVRE 50.

Who has experience with firmware upgrades on the ZVRE?

I’ve been reading Gary Russell’s ‘Legacy’ #VNA this past week. I’m about half way through so the intrigue is up and running but I wanted to say: I so dislike what the series has done with Ace…

Also she sleeps with way too many dudes, but that’s probably just the gay in me talking. #DoctorWho

EDIT: this is not “slut shaming” it’s just me wishing she was more overtly sapphic! Also that’s not the thing I don’t like, it’s the mercenary thing. Urgh I’m going to go.

I've started making a thing. It's far from finished, but at least it's starting to take shape. Also, I think that #RigExpert's AA-30.ZERO is a nice VNA in affordable price that is extremely hackable. After I've started playing with it on a PC I've thought that it would be even better to connect it to a ESP-based board so I can provide the measurements over wifi instead of an Arduino working only as a serial repeater - but maybe I'll get to that later.
