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. 15cm SMA male to male RG316 RF cable x 2Ĩ.NanoVNA V2 (S-A-A-2) is a 4GHz vector network analyzer (VNA) capable of measuring antennas, filters, duplexers, and amplifiers. NanoVNA host x 1 (including 4-inch touch screen, 2000mAh battery)Ģ. Optimized PCB layout, accommodating 1950mAh battery, more than 8 hours of useġ. The redesigned power management circuit further reduces power noise, reduces USB power interference, reduces charging current, and protects the batteryġ0. Solve the previous abnormality of NanoVNA-H near 6MHzĩ. When the fundamental wave is used, the output level of CH0 is increased to 0dBm, and the reflection measurement is more accurate Ĩ. Now the 5th harmonic can be used to measure to 1.5GHz ħ. Optimized the bridge to make full use of the Si5351's harmonics. DC dimming is added, it can be seen more clearly when used outdoors, and it is more comfortable to use indoors.Ħ. ABS shell, can effectively protect SMA connectors and buttonsĥ. In order to make it easier for geeks to create more possibilities, UART1 and PC14, PC15 interfaces are drawn on the PCB, which is convenient for DIY expansionĤ. Use an independent charge pump to power the mixer and add tantalum capacitors, which can further reduce power supply noiseģ. Due to the larger screen, there is more PCB space for installing components and batteriesĢ.
