Nanovna Vector Network Analyzer Antenna Analyzer Short Wave MF HF VHF UHF Talent

 

Considering the Needs of Domestic Customers, We Have Compiled the Latest Version of Chinese Large Font Firmware. for Customers Who Need Chinese Version, Take a Note in Chinese!

 

DIY Vector Network Analyzer, Referring to the Relevant Design of Edy555 (https://twitter.com/edy555) in Japan, Modified Some Circuits, Added Battery Management Circuits, and Redesigned PCB. A Simple and Practical Pc Control Software Is Designed, Which Can Be Used for Various Radio Design and Simulation Software to Export Touchstone (SNP) Files through PC Software. The Improved Frequency Algorithm Can Use the Odd Harmonic Extension of Si5351 to Support the Measurement Frequency of 900MHz, and Design a Metal Shielding Sheet, Which Can Reduce External Interference, Increase Isolation and Improve Measurement Accuracy.

 

 

The Launch of Nanovna Has Received Extensive Attention from Radio Enthusiasts and Electronic Instrument Enthusiasts. We Have Conducted a Lot of Discussions and Tests with Community Enthusiasts, the Article Written by Dr. George Steber Based on the Store Owner's Early Manual Version of Nanovna Has Landed on the Cover of the American Amateur Radio Association (ARRL)QEX Magazine from 2020 to February!

Now the Improved NanoVNA-H Rev3.4 Has Been Launched. Compared with Previous Versions, the Main Improvements Are as Follows:

1. The Bridge Is Optimized and the Harmonics of Si5351 Are Fully Utilized. Now the 5 Th Harmonic Can Be Measured to 1.5GHz;

2. When Using Fundamental Wave, the Output Level of CH0 Is Increased to 0dbm, and the Reflection Measurement Is More Accurate;

3. Resolve the Previous Exception That NanoVNA-H Occurred near 6MHz;

4. Reproduce the Designed Power Management Circuit, Further Reducing Power Noise, Reducing USB Power Interference, Reducing Charging Current and Protecting Battery;

5. Optimized PCB Layout, Holding 650MAh Battery;

6. Reserve the UART Interface to Facilitate DIY Expansion.

 

This Is a DIY Product That Provides Perfect Vector Network Measurement Function as Much as Possible in the Size of Credit Cards. Contains a 2.8-Inch Touch Screen, 650MAh Battery, Can Be Used Offline for 4 Hours, Tx/Rx Measurement, Can Measure the Complete S11 and S21 Parameters, If You Need to Obtain S12 and S22, you Need to Manually Replace the Transceiver Port Wiring. If There Are Other Imperfections, You Can Communicate with Me.
