NANOVNA-H4 advantage analysis:



1. 4-inch full-angle LCD screen, increased DC dimming, outdoor use can see more clear indoor use more comfortable,

2. The bridge has been optimized to make full use of the harmonics of Si5351, which can now be measured to 1.5GHz with the 5th harmonics;

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

4. Solve the previous NanoVNA-H anomaly near 6MHz;

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

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

7. Reserved UART interface, convenient DIY expansion;

8. Open mold to make a new ABS shell, light and convenient, to protect the machine;

9. The packaging is exquisite, which provides guarantee for the transportation safety after.
