How to be a Principal Engineer/Senior Principal Engineer/Senior Architect/fancy-sounding-title Engineer, a thread: 1.

🧵 How to build an RF lab on a budget? A hacker's guide to the most important tools for signal hacking/analysis. Let's first introduce a few concepts and tools before actually jumping into the specific brands and models. Depending on what you want to do, there are a few tools you need in your lab for frequency analysis, antenna testing, and RF measurements: 1. spectrum analyzer: one of the most important tools in an RF lab. A device that lets you "see" signals. Mostly come in 2 shapes: either standalone (benchtop or portable, but with its display, and works independent of a computer), or USB-based that needs a computer. It's like a receiver, receiving signals from its input port (e.g. from an antenna) and showing them to you. 2. signal generator: as the name says, a device to generate signals. Like a transmitter. Important for many use cases (testing antennas, receivers, and many other RF accessories) 1/7
