S-A-A-2 NanoVNA-F V2 Vector Network Analyzer Digital Nano VNA Tester MF HF VHF UHF USB Logic Antenna Analyzer Standing Wave

NanoVNA-F V2 portable vector network analyzer is a new product developed on the basis of NanoVNA-F. It uses a 4.3-inch IPS LCD display and an aluminum alloy case. It is equipped with a 5000mAh large-capacity lithium battery as standard. Support touching screen and side button operation, support Chinese and English interface. The design of this product is based on edy555’s NanoVNA and OwOcomm’s S-A-A V2, and deep optimization of the software is made on the basis of the previous product NanoVNA-F. The operation interface is compatible with NanoVNA-F, the measurement ranges is extended to 3GHz, and the dynamic ranges is larger. The measurement is more accurate and the operation is more convenient.

4.3-inch IPS LCD display, resolution 800*480, ultra-wide viewing angle, long-term use does not hurt your eyes.
All aluminum alloy case, sturdy and durable, effectively shielding electromagnetic interference to ensure measurement accuracy.
The radio frequency interface is SMA, which is convenient for connecting various tested parts.
Full touching screen design, with 3 side buttons at the same time, flexible and convenient operation.
Support Chinese and English interface.
Optimized UI design, convenient for users to perform measurement operations.
Support screen brightness adjustment.
The firmware can be upgraded through a virtual U disk, no programmer is needed, and the firmware can be upgraded through the included USB type-c data cable.
Standard fine quality calibration parts and RG405 phase-stable cable to ensure calibration accuracy.
Designed with USB power output interface, which can support 5V/1A power output.
Using 2A high current recharging IC, the recharging time is shorter.
Supporting host computer software, the host computer supports Chinese and English interfaces.
The screen images of the device can be obtained by taking a screenshot of the host computer.
Function: can measure S parameters, voltage standing waves ratio, Smith chart, phase, group delay, etc.

This is a DIY product with vector network measurement function. It includes a 2.8-inch touching screen, TX/RX measurement, can determine the complete S11 and S21 parameters, if you need to get S12 and S22, you need to manually replace the trans-ceiver port wiring.

The PC control software can export Touchstone (snp) files, which can be used for various radio design and simulation software.
The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 900MHz.
The 50k-300MHz frequency ranges of the si5351 direct output provides better than 70dB dynamic.
The extended 300M-600MHz band provides better than 50dB of dynamics, and the 600M-900M band is better than 40dB of dynamics.
Small and portable, easy to use, this project aims to provide an radio frequency gadget but useful instrument for enthusiast.
