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.
|
|
|
|
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

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 20.3 Cinnamon)
|
|
|
|
### Binary releases
|
|

|
You can find 64bit binary releases for Windows, Linux and MacOS under
|
|
<https://github.com/NanoVNA-Saver/nanovna-saver/releases/>
|
|
|
|
Versions older than Windows 7 are not known to work.
|
|
|
|
#### Windows 7

python3 nanovna-saver.py
|
|
|
|
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.
|
|
|
|
|
|
|
|
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.
|
|
|
|
### Frequency bands
|
|
|
|
Open the "Display setup" window to configure the display of frequency bands. By
|
|
clicking "show bands", predefined frequency bands will be shown on the
|
|
frequency-based charts. Click manage bands to change which bands are shown,
|
|
and the frequency limits of each. Bands default and reset to European amateur
|
|
radio band frequencies.
