Temperature drift cancellation, only available in the V2 Plus4 and VNA6000 series, gives you repeatable and reliable measurements, allowing you to keep calibrations for longer (>3 months compared to 90dB real dynamic range, achieving similar results as professional VNAs, and allows measuring duplexers. It is a complete redesign using our new VNA-R architecture, which features the following improvements: V2 Plus4 fixes the drift and linearity issues with older NanoVNA/S-A-A-2 based analyzers. 
This is the official NanoRFE/HCXQS store and here you can find guaranteed original NanoRFE products.
Imported from USA (Sizes & Specifications are based on the USA Market).NanoVNA V2 Plus4 4GHz second generation NanoVNA vector network analyzer, our own design. firmware and hardware repository at /ttrftech/NanoVNAPackage include NanoVNA host (with battery)(without case) x1, USB Type-C data cable x1, 30mm SMA male to male RG174 RF cable x2, SMA simple calibration kit x1, SMA female to female connector x1. If you need to obtain S12 and S22, you need to manually replace the transceiver port wiring. The TX/RX method can measure the complete S11 and S21 parameters. The default firmware of AURSINC Nanovna main function is used for antenna performance measurement. 
Added a case, which is protective and dust-proof.
Designed a practical and simple control application on PC, you can download touchstone(SNP) files for radio design and simulation software. 
The metal shield (no enclosure)for tiny vector network analyzer is designed to reduce the external interference and improve the measurement accuracy.This is a DIY product that provides perfect vector network measurement capabilities(no enclosure).
