Displaying markers, and the impedance, VSWR, Q, equivalent capacitance/inductance etc.Displaying data on multiple chart types, such as Smith, LogMag, Phase and VSWR-charts, for both S11 and S21.Averaging data for better results particularly at higher frequencies.Splitting a frequency range into multiple segments to increase resolution (up to >10k points).Reading data from a NanoVNA - Compatible devices: NanoVNA V1 and V2.Main development is currently done on Linux (Mint 20.3 Cinnamon) NanoVNA-V2 Plus4 Hardware Vector Network Analyzer 50KHz-4GHz Antenna Analyzer. The software was written in Python on Windows, using Pycharm, and the modules PyQT5, numpy, scipy and pyserial. NanoVNA V2 Plus4 Pro 4G Vector Network Analyzer 50KHz-4GHz VNA Antenna Analyzer. This software connects to a NanoVNA and extracts the data for display on a computer and allows saving the sweep data to Touchstone files. Broberg and supports both V1 and V2 hardware. Otherwise, you can update your firmware using Python and the bootload_firmware.py script.Įnsure you have Python version 3, and install pyserial.NanoVNA Saver is a tool developed by Rune B.
Restart your NanoVNA as described below and follow the instructions in NanoVNAv2-QT. You can update the firmware using (NanoVNAv2-QT]( ). If you have an intact bootloader already installed in your NanoVNAv2, there are several ways to update the firmware. Updating firmware using the serial bootloader If your device already has a working serial bootloader, you can upload the firmware without needing extra hardware. You can upload the firmware binary to that address using an ST-Link.
The NanoVNA V2 firmware is installed at address 0x8004000. Some reports indicate that the NanoVNAv2 cannot be powered via the 3.2v supply from the ST-Link, but should be powered from its own battery. To install the bootloader on a new GD32F303, you will need to use an ST-Link device, of which many inexpensive clones are available. Buy Nvarcher Plus4 NanoVNA V2 4GHz Vector Network Analyzer 4 Inch TFT 50KHz-4GHz Shortwave HF VHF UHF 70-90dB With 3200mAh with fast shipping and top-rated. The bootloader should be loaded at address 0x8000000, the start of the GD32F303 flash section. Please do not attempt to use a standard USB DFU tool. Instead, a serial bootloader program is installed. The GD32F303 processor does not support USB DFU mode like the STM32 chips do.
