This is a student engineering capstone project from Grand Valley State University's Padnos College of Engineering, documenting Phase 1 of building a large-display spectrum analyzer for use in an RF R&D development lab. Unlike the shorts and quick DIY builds that dominate this week's candidate list, this video shows a real engineering process — requirements gathering, system architecture decisions, and the tradeoffs that go into designing a piece of test equipment from scratch.

Spectrum analyzers are foundational RF instruments, and seeing one designed from the ground up gives viewers a rare window into questions that commercial datasheets hide: how do you choose a display resolution appropriate for the frequency span you want to visualize? What's the signal path from antenna to screen? How do you partition the work between analog front-end, digitization, and rendering?

Student capstone videos are often underrated because the presenters are learning alongside the audience — you get to see them reason through problems rather than present polished conclusions. For anyone curious about RF instrumentation, embedded display systems, or how engineering teams scope a multi-phase hardware project, this is a much more substantive watch than yet another RF transmitter/receiver explainer short.
