NanoVNA-H4: Portable Vector Network Analyzer 10kHz-1500MHz  

The NanoVNA-H4 kit includes an open-hardware vector network analyzer designed by ttrftech (GitHub), enabling easy testing of most RF devices. A portion of the proceeds from the sale of this kit is paid to the ttrftech team to continue the development of NanoVNA-H4. The RF sections are EMI shielded, reducing potential interference and improving the accuracy of the device.

NanoVNA-H4 features a 4" TFT touchscreen with a user-friendly interface that allows for S-parameter measurements (S11 and S21), SWR, phase, and Smith chart capabilities.

It is protected by an ABS case and is equipped with a 1950mAh battery, making the NanoVNA ideal for portable measurements and other operations.

It can measure frequencies from 10kHz to 1500MHz - and even better with appropriately modified firmware (note that values may be outside of intended operational lower frequency). Frequency accuracy is 0.5 PPM or better, RF output voltage is 13 dBm, and SWR < 1.1.

The NanoVNA-H4 can also communicate with your PC via USB-C (serial mode). A USB cable is included in the package.
