Nanovna-F_V2 3G Mini vector network analyzer



    NanoVNA-F_V2 is a new generation of portable, stand-alone vector network analyzer with 4.3" IPS LCD screen, metal enclosure, 5000mAh battery and SMA connectors. It is a product based on edy555's NanoVNA and OwOComm's S-A-A-V2. The measurement frequency range of NanoVNA-F V2 is up to 3GHz. The S21 dynamic range is better than 70dB at 50kHz-1.5GHz and better than 60dB at 1.5GHz - 3GHz. NanoVAN-F V2 can work continuous for 7 hours due to the large capacity battery and low-power design.

NanoVNA-F_V2 hardware features include and are not limited to the following improvements:

1. Use 4.3-inch IPS TFT LCD & resistive touch screen, with a larger view angle and can be  seen clearly outdoor.

2. Aluminum case, very strong and durable, it can be effective in electromagnetic noise suppression and shielding.

3. Use large capacity 5000mAh/3.7V lithium battery, standby time is longer, it can work continuous for 7 hours and expand a USB interface. Usually, it can be used as a power bank when the instrument is not used.

4. Whole touch screen design, with 3 side buttons, make it flexible and convenient when used

5. Support screen brightness adjustment,the screen is clear even in the sun.

6. Support Chinese and English menu switching;

7. Upgrade the user program(firmware) by virtual U disk(16MB SPI Flash Memory Inside).

8. Standard aluminium case to protect SMA head and reduce the interference of external electromagnetic wave to instrument.

9. 2A large current charging IC design, charging time is more shorter than before.

10. Supporting host software,  the host software support Chinese and English menu switching.

11. Supporting screen shot, the image can be save by the host software.
