LCD Upgrade for the HP 141T Spectrum Analyzer [Part 1]

In this video I demonstrate my progress so far on building an intelligent LCD display upgrade for the HP 141T. I use an STM32F746G discovery board with a 4" touchscreen, and demonstrate a few neat features: - Real-time spectrum display with graticules etc, that works on the slowest up to the fastest timebase - A waterfall display mode - A normalization function that makes insertion loss measurements much easier. I also take a brief look at the codebase (which is very hacky at the moment!) More features and hardware connections will be in a future video!
