I knew this was going to be Shahriar from TheSignalPath. If you even have a passing interest in electronics or radio, I can't recommend his channel enough. He's regularly doing teardowns and even repairs on remarkably complex (and expensive!) test equipment from the past few decades. RF is weird and you'll see some complex and alien physical configurations in the equipment that many times look like dark arts. He puts a lot of effort into his videos and the scenarios he creates to demonstrate the power that this technology brings to the table. This 128GHz FFT is insane. I'm honestly a little surprised that this doesn't have ITAR regulations on it: [VIDEO]
