The nanoVNA H4 is the next edition of the well-known antenna analyzer.
With the nanoVNA H4:
- measure the inductance and capacitance of reactive loads
- measure antenna characteristics
- check antenna matching
- perform comparative measurements of the same circuit (current measurement vs. a measurement saved in memory)
- generate a Smith chart
- tune an antenna to resonance
- you can measure filter characteristics
Of course, besides the measurement, which can be viewed immediately on the 2.8-inch color touchscreen LCD, measurements can also be viewed on a computer.
Free software available for download (link below) lets you view measurement results live on a PC. With the software, you also gain the ability to save the measurement results
The analyzer comes with a calibration kit, and thanks to its two ports you can perform two measurements simultaneously.
