Length of the coaxial cable and locate cable faults by calculating the Timeĭomain measurements are widely used by the community to quickly measure the And thanks to the excellent performance of the improved NanoVNA-H Rev3.4, edy555 has increased the frequency upper limit to 2.7GHz in his 0.7.0 firmware, but users should be aware of the substantial noise floor and other uncertainties above 1.5GHz.Ĭho45 also added TDR (Time Domain Reflectometer) functionality to the NanoVNA. With community collaborations, the improved NanoVNA-H rev3.4( and later versions ) and NanoVNA-H 4 can further achieve 40dB dynamic range up to 1.5GHz. NanoVNA can achieve 40dB dynamic range at 900MHz.

Updating his firmware to enable harmonic extensions. You like the fun of DIY or you plan to customize it. Pre-assembled NanoVNA-H is one of the most convenient options to have a NanoVNA Versions of pre-assembled NanoVNA at very affordable prices. The latest version is NanoVNA-H rev3.6 and NanoVNA-H4 rev4.3. The measurement frequency up to 900MHz by using harmonics of the internal frequencyįollow this link to check the firmware and hardware of Hugen's redesigned version of NanoVNA. NanoVNA was designed to work ranging from 50kHz-300MHz. Hugen’s NanoVNA-H improved NanoVNA with a 5V DC-DC boost converter, which enables stable operation driven solely by a 3.7V Li-ion battery.

Therefore, Edy555’s original version was unable to be stably powered from 3.7V Li-ion battery pack, and requires external USB power supply to work without flaws. NanoVNA's mixer SA612A needs stable 5V power supply to work. It is a low cost yet high performance (at its price point) vector network analyzer (VNA), with LCD display, and can be powered from a 3.7V Li-ion battery.Īs known by most hobbyists, NanoVNA has become the most popular VNA and antenna analyzer project in the community since its release in 2019.Įdy555 hosts his firmware and hardware repository at įollow this link to get the original schematics and firmware documentation.Hugen improved Edy555's original design by introduction two extensions: NanoVNA is a handheld Vector Network Analyzer (VNA) with small outline, originally designed by edy555.
