Product Description If you have any questions, please contact customer service first, do not open disputes easily, thank you! Description: NanoVNA-F V2 portable vector network analyzer is a new generation product developed based on NanoVNA-F. It uses a 4.3-inch IPS LCD screen and aluminum alloy. It is equipped with a 5000mAh large capacity lithium battery as standard. The battery life can reach 7 hours. Support touch screen and side button operation, support Chinese and English interface. The design of this product is based on edy555's NanoVNA and OwOcomm's SAA V2, and deep optimization of the software is made based on the previous generation product NanoVNA-F. The operation interface is compatible with NanoVNA-F, the measuring range is extended to 3GHz, and the dynamic range is wider. The measurement is more accurate and the operation is more convenient. Feature: 1. 4.3-inch IPS LCD screen, resolution 800 * 480, ultra-wide viewing angle, long-term use does not hurt your eyes; 2. All aluminum alloy, sturdy and durable, effectively shielding electromagnetic interference to ensure measurement accuracy; 3. The body size is about 125mm * 75mm * 20mm, compact and portable; 4.
