Features
 

1. The 4-inch full-view LCD screen has added DC dimming, and it can be seen more clearly when used outdoors, and indoor use is more comfortable.

2. Optimized the bridge to make full use of the Si5351's harmonics. Now the 5th harmonic can be used to measure to 1.5GHz;

3. When the fundamental wave is used, the output level of CH0 is increased to 0dBm, and the reflection measurement is more accurate;

4. Solve the abnormality of NanoVNA-H near 6MHz;

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

6. Optimized PCB layout, containing 1950mAh battery, more than 8 hours of use;

7. Reserved UART interface, convenient for DIY expansion;

8. The new ABS shell is made by opening the mold, which is light and convenient to protect the machine;

9. The packaging is exquisite to provide guarantee for the subsequent transportation safety.

·→[Last Upgraded Version] This NanoVNA-H4 has a 4-inch LCD touch screen, carrying a 1950mAh battery that can be charged or powered by USB. Work longer

·→[Improved Frequency Algorithm] The vector network analyzer can use the odd harmonic extension of si5351 to support measurement frequencies up to 1.5GHz. The 50K-300MHz frequency range directly output by si5351 provides more than 70dB dynamics, the extended 300M-900MHz frequency band provides more than 60dB dynamics, and the 900M-1.5GHz frequency band provides more than 40dB dynamics.

·→ [Small, portable and powerful] This antenna analyzer is a DIY product that provides perfect vector network measurement capabilities, compact and handheld. The main function of the default firmware is for antenna performance measurement. The TX/RX method can measure the complete S11 and S21 parameters (you need to manually replace the transceiver port wiring).

·→ 【PC connection】Using the PC software NanoVNASaver, it can connect to NanoVNA and extract data to display on the computer and save it to a Touchstone file. We can export Touchstone (snp) files through PC software to understand various radio design and simulation software

·→ [Improved accuracy] Equipped with ABS plastic shell, while using a strong and safe power supply. Enhanced performance in all directions
