NanoVNA Vector Network Analyzer Antenna Analyzer Shortwave MF HF VHF UHF Antenna Analyzer

 

Considering the needs of domestic customers, we have compiled the latest version of Chinese large font firmware. Customers who need the Chinese version should place an order and note 'Chinese' in the remarks!

 

DIY Vector Network Analyzer, Referencing Japan edy555(https://twitter.com/edy555) related design, modified some circuits, added battery management circuit, and redesigned the PCB.Designed a simple and practical PC control software that can export Touchstone(snp) files for use in various radio design and simulation software through the PC-side software.The improved frequency algorithm can utilize the odd harmonic expansion of si5351 to support measurement frequencies up to 900MHz. A metal shielding sheet has been designed to reduce external interference and increase isolation for improved measurement accuracy.

 

 

The launch of NanoVNA has attracted widespread attention from radio enthusiasts and electronic instrument enthusiasts. We have conducted extensive discussions and tests with community enthusiasts. Dr. George Steber's article based on the shop owner's early handmade version of NanoVNA has been featured on the cover of the American Radio Relay League (ARRL) QEX Magazine for January-February 2020!

Now the improved NanoVNA-H Rev3.4 has been launched, and the main improvements compared to previous versions are as follows:

1. Optimized the bridge to fully utilize the harmonics of Si5351; now capable of measuring up to 1.5GHz using the 5th harmonic

2. When using baseband, the CH0 output level is increased to 0dBm, making reflection measurement more accurate;

3. Resolve the previous abnormality of NanoVNA-H near 6MHz;

4. Reproduce the designed power management circuit to further reduce power supply noise, reduce USB power interference, reduce charging current, and protect the battery;

5. Optimized PCB layout to accommodate 650mAh battery;

6.Reserved UART interface for easy DIY expansion.

 

This is a DIY product that provides comprehensive vector network measurement capabilities in a credit card-sized dimension.Includes a 2.8inch touch screen, 650mAh battery, can be used offline for 4 hours, TX/RX measurement mode, can measure complete S11 and S21 parameters. If you need to obtain S12 and S22, you need to manually change the transceiver port wiring.If there are any other areas that need improvement, you can communicate with me.
