At my former job we had a rather large faraday cage for testing telco equipment. Two things surprised me: 1) It is more fiddly to ensure a room-sized faraday cage doesn't leak RF than I thought. It is really easy to make mistakes that compromises experiments. 2) There was a bath-towel sized piece of cloth that came with one of the expensive Rohde & Schwarz instruments that was astonishingly effective at blocking signal.

So I mainly used the room because that's where the magic blanket was - which was easier to use than ensuring the room was set up correctly.

I see one of the founders (Ulrich Rhode) of Rhode and Schwarz on amateur radio some times, and I always ask for test equipment and he always says no.
I see you are from <insert whatever company you are at is>, can you please send me a lifetime supply of whatever you make / have / sell please?
Hey, when my customers ask they are free to have a lifetime supply of our product! It’s free to anyone!
Maybe stop asking then?
That's very cool, he's basically test equipment royalty. But he's the son of one of the founders - Rhode & Schwarz was founded in the 1930's.
It’s good natured ribbing usually exchanged over QSL cards. I didn’t know he was the son! Ulrich never misses a QSL card for me. Cool dude!
I once tried to acquire a RS PR100 like the one used in the test here. Turns out they cost more than a fancy car!
I wonder how much more capable they are than the cheap crap I can afford.
A lot! An Ettus USRP + GNURadio could get you part of the way, but you then you don't get the nice handheld form factor and ruggedized chassis.
