S parameters export, custom calibration kit parameters & advanced calibration methods (NanoVNA-QT software).

No noticeable drift, allowing calibrations to be kept for > 3 months (compared to 90dB, achieving similar results as professional VNAs, and allows measuring duplexers.

The main improvements in NanoRFE's NanoVNAs are: The wide frequency range covers common cellular, Wi-Fi, and IoT bands, as well as HF, VHF, and UHF amateur radio bands. It uses our new VNA-R architecture featuring temperature drift cancellation and reduced crosstalk, showing no visible drift in all indoor conditions.Ĭompared to other NanoVNA versions, V2 Plus4/Plus4 Pro do not use harmonics for measurements, improving performance significantly, achieving 90% less trace noise, and is the only low cost VNA to give you highly repeatable and reliable measurements comparable to professional instruments. V2 Plus4 is the latest design which fixes the drift and linearity issues with older versions. It is a new from-scratch design by HCXQS/NanoRFE not based on the earlier edy555 V1 design. This page was translated from cho45’s NanoVNA User Guide.NanoVNA V2 (S-A-A-2) is a 4GHz vector network analyzer (VNA) capable of measuring antennas, filters, duplexers, and amplifiers.

Calibrate according to the calibration method.

To do firstīefore you can use it, you must first calibrate it. First, calibrate as follows.

In either case, the input is converted to an intermediate frequency of 5kHz. The signal is converted from analog to digital at 48kHz sampling. Digital data is signal processed by the MCU. Note that there is always a fundamental wave input, especially when checking the amplifier gain. The local frequency of NanoVNA is 50kHz to 300MHz. For higher frequencies, use harmonic mode. The fundamental wave is not attenuated even in harmonic mode. The usage modes for each frequency are as follows.

NanoVNA measures the reflection coefficient and transmission coefficient for 101 points in the frequency band to be measured. The following items that can be calculated from these can be displayed. VNA (Vector Network Analyzer) measures the frequency characteristics of reflected power and passing power of a high frequency network (RF Network). Start using NanoVNA What you need to work
