Product Information

IMPROVED FREQUENCY ALGORITHM:The Vector Network Analyzer can use the old harmonic extension of si5351 to support the measurement frequency up to 1. This Antenna Analyzer is provides outstanding vector network measurement capabilities and perfect for evaluating antenna resonance and SWR.

The NanoVNA-H4 comes in a well fitted ABS case and provides guards for the side mounted port connectors. If anyone else that has received a NanoVNA-H4 would try the above and let me know the results I'd appreciate it.NanoVNASaver is a software that allows you to interface with the NanoVNA-H4 Vector Network Analyzer and conveniently manage the measurements and data on a computer. Merle's confirmation was enough for me to report an issue to hugen on his GitHub page ( https://github.

Install NanoVNA-Saver: Download the latest version of NanoVNASaver compatible with your operating system from the GitHub repository https://github. This includes: harm to minors, violence or threats, harassment or privacy invasion, impersonation or misrepresentation, fraud or phishing. locks up under the same conditions, which hints there might be a fundamental problem with the firmware, perhaps a memory leak. c. Move the marker across the frequency range by tapping the ‘<‘ and ‘>’ buttons or dragging the marker on the screen.

As a result, you could actually be detuning your antenna from the resonant frequency that you want, by aiming for a 1:1 SWR at 50 ohms. The latest versions of firmware, drivers and updated documentation can be downloaded from this Google Drive as well as from Github and Github2. A separate charge pump to power the mixer and tantalum capacitors were added to reduce the power supply noise.
