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!)
