NanoVNA-Q is firmware for NanoVNA vector network analyzer.
Original NanoVNA firmware and hardware was developed by @edy555 and it's source code can be found here: https://github.com/ttrftech/NanoVNA
Later, @hugen79 introduced a new PCB (NanoVNA-H) and improvements for firmware and device become very popular. @hugen79 project can be found here: https://github.com/hugen79/NanoVNA-H
NanoVNA-Q is based on @edy555 code, includes improvements from @hugen79 and is targeted for NanoVNA-H hardware.
The main goal of this project is to fix bugs, improve stability, measurement quality and usability.
The main differences with original firmware:
- added impedance label for current marker
- improved noise floor, imbalance gain, measurement quality and data transfer to PC
- added scanraw command (allows to read raw gamma data for unlimited point count with no calibration apply)
- added color command (allows to customize trace colors)
- fixed frequency rounding issues
- fixed multithreading issues
- added si5351 PLL lock hardware check
- fixed couple of bugs
