NanoVNA-F, FreeRTOS version of edy555's NanoVNA.
"VNA" means: 矢量网络分析仪器 / Vector Network Analyzer
NanoVNA-F is a product made by BH5HNU based on the Open Source Project of NanoVNA(https://ttrf.tk/kit/nanovna/).
Thanks to hugen's creative idea of use the harmonic of Si5351, We build NanoVNA-F and expand the measure frequency up to 1GHz, which S11 still have 40dB dynamic range At 1GHz.

Hello everyone, it is necessary to state that at present we only produce -F machines with metal case.
We do not resist enthusiasts buying machines from other suppliers, but enthusiasts need to have a certain discrimination ability: choose a supplier with good evaluation, and the price of the machine is trustworthy at around $ 120.
Like what hwalker in groups.io/nanovna-f said "be aware that some vendors are scammers and the only way to protect yourself is buying from a reputable source."
Recently we found a bad clone of the -F machine on AliExpress / eBay. We have open sourced all the code on github, but this clone is still badly made. ╮(╯▽╰)╭
As the picture shown below, We want enthusiasts to stay away from these crude products.
NanoVNA-F can measure S parameters, Voltage Standing Wave Ratio(SWR), Phase, Group Delay, Smith chart and so on
NanoVNA-F hardware features include and are not limited to the following improvements:
- Use 4.3-inch IPS TFT LCD & resistive touch screen, with a larger view angle and can be seen clearly outdoor.
- Use large capacity 5000mAh/3.7V lithium battery, standby time is longer, and expand a USB interface. Usually, it can be used as a power bank when the instrument is not used.
- The Lipo Charing IC to changed to IP5306(with 2A high charing current) , make the charging time shorter.
- Use a larger and better operating level.
- Support Chinese and English menu switching;
- Upgrade the user program(firmware) by virtual U disk(16MB SPI Flash Memory Inside).
- Standard aluminium case to protect SMA head and reduce the interference of external electromagnetic wave to instrument.
