NANOVNA-H Updated Version 2.8 Inch TFT Vector Network Antenna Analyzer 50Khz-1.5Ghz MF HF VHF UHF with SD Card Slot Without Card, 4 Inch

1. A 4-inch LCD screen is used. Due to the larger screen, there is more PCB space for installing components and batteries
2. Use an independent charging pump to power the mixer and add tantalum capacitors, which can further reduce the power supply noise
3. In order to facilitate Geeks to create more possibilities, UART1 and PC14, PC15 interfaces are designed on the PCB, which is convenient for DIY expansion
4. ABS shell, can effectively protect SMA connectors and buttons
5. DUMMING DC is added, it can be seen more clearly when used outdoors, and it is more convenient to use indoors.
6. Optimized the bridge to make full use of the harmonics of SI5351. Now the fifth harmonic can be used to measure at 1.5GHz;
7. When the fundamental wave is used, the output level of CH0 is increased to 0DBM, and the reflection measurement is more accurate;
8. Solve the previous Nanovna-H anomaly near 6 MHz
9. The redesigned power management circuit further reduces power noise, reduces USB power interference, reduces charging current and protects the battery
10. Optimized PCB layout, adapting 1950mAh battery, more than 8 hours of use
