Introduction
NanoVNA-F V3 is a Portable Vector Network Analyzer (VNA) with frequency range of 1MHz ~ 6GHz. It can be used for S11 and S21 measurements. The S21 dynamic is 65 dB, while the S11 dynamic range is 50 dB.
NanoVNA-F V3 is suitable for antenna testing of MF/HF/VHF/UHF/SHF bands, such as shortwave antennas, ISM band antennas, WiFi antennas, Bluetooth antennas, GPS antennas, etc. It can also be used to measure filters, amplifiers, attenuators, cables, power dividers, couplers, duplexers and other RF components. NanoVNA-F V3 supports a variety of display formats: LogMag, Linear Mag, Phase, Smith R+jX, Smith R+L/C, VSWR, Polar, Group delay, Resistance, Reactance, etc.
In addition, NanoVNA-F V3 supports TDR function which is useful for cable lengths measurement.
NanoVNA-F V3 is designed with metal case, which is durable and can effectively shield electromagnetic interference. The dimension of NanoVNA-F V3 is 125mmx75mmx20mm. The RF interface of NanoVNA-F V3 is SMA connector witch can be used to connect DUTs directly.
With the optimally designed signal processing system, the scan speed of NanoVNA-F V3 is upto 200 points/s and the maximum scanning points is up to 801.
The screen of NanoVNA-F V3 is a 4.3-inch high-brightness IPS with resistive panel, which allows users to see the screen contents clearly in outdoor. NanoVNA-F V3 adopts a full touchscreen design, with 3 physical buttons, users can quickly set frequency range, scale, turn on/off traces, add/delete markers, and so on. The operation is quite convenient and smooth.
The NanoVNA-V3 has 4500mAh lithium-ion batteries with a battery life of up to 5 hours. The charging interface is USB Type-C, and the Type-C cable can be used to charge the device and also for data transfer.
