Feature: 1. 4.3 INCH IPS LCD TOUCH SCREEN: NanoVNA F V2 vector network analyzer adopts 4.3 inch IPS LCD display with ultra wide viewing angle, which is not harmful to eyes for long term use. Full touch screen design, 3 side buttons at the same time, flexible and convenient operation. 2. 50KHZ‑3000MHZ: Network analyzer extends to 50KHz‑3000MHz with improved dynamic range up to 80db. It can be used to debug duplexers with more accuracy. Can measure S parameters, voltage standing wave ratio SWR, phase diagram, group delay, Smith chart, etc. 3. 5000MAH LI ION BATTERY: Antenna analyzer has built in 5000mAh Li ion battery with standby time up to 7 hours. Adopt high current 2A charging IC to shorten the charging time and extend 5V 1A USB output interface. Support Chinese and English interface, screen brightness adjustment, and support the upper computer. 4. METAL SHIELD: Touch screen antenna analyzer is robust and durable. RF front end is designed with metal shield, which makes S21 dynamic range better than 80dB in the whole frequency range. RF interface is SMA, which is convenient to connect various components under test. 5. TEST RANGE: Vector network analyzer is based on OwOComm's S A A 2 design and can test the standing wave and impedance of antennas, the insertion loss, isolation and standing wave of filters, the attenuation, shortening factor and phase of cables, and the amplification of antenna amplifiers. 6. FREQUENCY METER FUNCTION: Network analyzer has a frequency meter function, can measure the cable length, group time delay powerful, the most important thing is also can debug the uv band frequency duplexer. Effective shielding electromagnetic interference to ensure measurement accuracy.
