        ## Introduction
        
        This software connects to a NanoVNA and extracts the data for
        display on a computer and allows saving the sweep data to Touchstone files.
        
        <a href="#current-features"></a>
        
        ### Current features
        
        - Reading data from a NanoVNA -- Compatible devices: NanoVNA, NanoVNA-H,
          NanoVNA-H4, NanoVNA-F, AVNA via Teensy
        - Splitting a frequency range into multiple segments to increase resolution
          (tried up to >10k points)
        - Averaging data for better results particularly at higher frequencies
        - Displaying data on multiple chart types, such as Smith, LogMag, Phase and
          VSWR-charts, for both S11 and S21
        - Displaying markers, and the impedance, VSWR, Q, equivalent
          capacitance/inductance etc. at these locations
        - Displaying customizable frequency bands as reference, for example amateur
          radio bands
        - Exporting and importing 1-port and 2-port Touchstone files
        - TDR function (measurement of cable length) - including impedance display
        - Filter analysis functions for low-pass, high-pass, band-pass and band-stop
          filters
        - Display of both an active and a reference trace
        - Live updates of data from the NanoVNA, including for multi-segment sweeps
        - In-application calibration, including compensation for non-ideal calibration
          standards
        - Customizable display options, including "dark mode"
        - Exporting images of plotted values

        ## Running the application
        
        The software was written in Python on Windows, using Pycharm, and the modules
        PyQT5, numpy, scipy and pyserial.
        Main development is currently done on Linux (Mint 21 "Vanessa" Cinnamon)
        
        ## Installation
        
        ### Binary releases
        
        You can find current binary releases for Windows, Linux and MacOS under
        <https://github.com/NanoVNA-Saver/nanovna-saver/releases/latest>
        
        The 32bit Windows binaries are somewhat smaller and seems to be a
        little bit more stable.
        
        [Detailed installation instructions](docs/INSTALLATION.md)
        
        ## Using the software
        
        Connect your NanoVNA to a serial port, and enter this serial port in the serial
        port box.  If the NanoVNA is connected before the application starts, it should
        be automatically detected. Otherwise, click "Rescan". Click "Connect to device"
        to connect.
        
        The app can collect multiple segments to get more accurate measurements. Enter
        the number of segments to be done in the "Segments" box. Each segment is 101
        data points, and takes about 1.5 seconds to complete.
        
        Frequencies are entered in Hz, or suffixed with k or M.  Scientific notation
        (6.5e6 for 6.5MHz) also works.
        
        Markers can be manually entered, or controlled using the mouse. For mouse
        control, select the active marker using the radio buttons, or hold "shift"
        while clicking to drag the nearest marker. The marker readout boxes show the
        actual frequency where values are measured.  Marker readouts can be hidden
        using the "hide data" button when not needed.
        
        Display settings are available under "Display setup". These allow changing the
        chart colours, the application font size and which graphs are displayed.  The
        settings are saved between program starts.
        
        ### Calibration
        
        _Before using NanoVNA-Saver, please ensure that the device itself is in a
        reasonable calibration state._
        
        A calibration of both ports across the entire frequency span, saved to save
        slot 0, is sufficient.  If the NanoVNA is completely uncalibrated, its readings
        may be outside the range accepted by the application.
        
        In-application calibration is available, either assuming ideal standards or
        with relevant standard correction. To manually calibrate, sweep each standard
        in turn and press the relevant button in the calibration window.
        For assisted calibration, press the "Calibration Assistant" button.  If desired,
        enter a note in the provided field describing the conditions under which the
        calibration was performed.
        
        Calibration results may be saved and loaded using the provided buttons at the
        bottom of the window.  Notes are saved and loaded along with the calibration
        data.
        
        ![Screenshot of Calibration Window](https://i.imgur.com/p94cxOX.png)
        
        Users of known characterized calibration standard sets can enter the data for
        these, and save the sets.
        
        After pressing _Apply_, the calibration is immediately applied to the latest
        sweep data.
        
        \! _Currently, load capacitance is unsupported_ \!
        
        ### TDR
        
        To get accurate TDR measurements, calibrate the device, and attach the cable to
        be measured at the calibration plane - i.e. at the same position where the
        calibration load would be attached.  Open the "Time Domain Reflectometry"
        window, and select the correct cable type, or manually enter a propagation
        factor.
        
        ### Measuring inductor core permeability
        
        The permeability (mu) of cores can be measured using a one-port measurement.  Put one or more windings on a core of known dimensions and use the "S11 mu" plot from the "Display Setup".  The core dimensions (cross section area in mm2, effective length in mm) and number of windings can be set in the context menu for the plot (right click on the plot).
