NanoVNA is an open source hardware project, everyone can be free to clone and DIY, but we hope you can do more understanding before you do it, there are some customers reflected that they have bought the low quality nanoVNA from other sources. We have found some low quality clones on the Internet which claimed have completed the project. Buying such hardware may be harm on NanoVNA performance, or leading to measurement error.

Our supplier will test before shipment and connect directly to the SMA port for calibration, the calibration data is stored in state 0, and the boot will load the status 0 data directly.
