The battery is charged via a USB-C socket with max. The NanoVNA-F V2 has a built-in 5000 mAh battery. This is more than sufficient to perform the usual tests such as SWR, impedance etc. The dynamic range for reflection measurements (S11) is 70 dB or better up to 1.5 GHz and 60 dB or better in the range from 1.5 to 3 GHz. The maximum output power depends on the frequency and is between -14 and -9dBm. measurement of impedance, SWR, attenuation, matching, cable length and much more. This allows reflection and transmission measurements, i.e. Two SMA sockets are available for measuring the S-parameters S11 and S21. The analyser uses a robust aluminium housing, the 4.3' IPS LC display (800 x 480 px) offers a wider viewing angle and better brightness, which improves readability even in bright sunlight. The NanoVNA-F V2 is a continued development of the well-known NanoVNA analyser. Frequency Counter, Near Field Receivers.Morse keys, electronic keyers, accessories.

Stationary, directional antennas (Yagi, X-Quad).The main board connects to a PC through usb and communicates via a virtual serial port device the PC software sets the frequency and other parameters by sending two-byte register write commands, and the device sends averaged vector values representing magnitude and phase of measured waves.Output signal level (configurable in software): -20dBm to 10dBm, with 1dB increments.Frequency range: guaranteed 137MHz - 2500MHz, typical 135MHz - 3500MHz.vhdl: circuitry implemented on the fpga.pcb: schematics, pcb layouts, and simulation files.libxavna: C & C++ library for accessing the hardware, see README.md in subdirectory for more info.A simple and cheap vector network analyzer, including support software.
