Update 17/01/2020: New .exe for 0.2.2-1 uploaded, which fixes a crash when running a continuous sweep after calibration is done.
Finally time for a little update to NanoVNA-Saver - my Christmas and New Year holiday was busier than anticipated, and I haven't done much to the software during that period! None the less, here is an update.
New feature: Device management and screenshots There is now a "Manage" button next to the "Connect to NanoVNA" button, which will let you see a few more details about the connected device, as well as - if supported by the firmware - grab screenshots of the device screen. This is a work in progress.
New marker values: Polar coordinates. You can now set the markers to display S11/S21 polar coordinates.
New feature: Sweep names You can put in a sweep name (find it under Sweep Settings) which is displayed in the charts. This was requested by some users.
New feature: Zoom in TDR charts This is fairly self-explanatory: You can zoom in on the TDR charts. :-)
Bug fix: Through calibration value The through calibration was apparently set up to expect a reflected value, not a transmitted value - which skewed the calibration values. This has been changed - I will be happy to hear if it's working for you!
Code cleanup: Holger has helped me a lot by cleaning up the marker code, and is working on even more changes. The code looks less like a prototype as each day passes. ;-)
As ever, I welcome all feedback!
This release is a minor update to the 0.2.0 release: New feature: Capacitance and Inductance charts These new charts display the calculated series equivalent Capacitance and Inductance against frequency.
New feature: Panning and modified zooming You can now hold the middle mouse button to pan a zoomed chart, or hold shift or control to only zoom the value or frequency axis when zooming using the mouse wheel.
Moving markers using the arrow keys After placing a marker on a chart by clicking with the mouse, it's now possible to move the marker immediately using the arrow keys.
Experimental feature: Port extension/Offset delay The calibration window has a new experimental feature. You can set an offset delay, which I'm told is useful for compensating for cables used when measuring without doing a full calibration. The value is applied immediately when changed, and is not connected to the other calibration features. Feedback on this feature is specifically requested.
Additionally, a number of bugfixes have been made, based on your feedback - Thank you! A lot of tidying has happened on the back end of the code, as well as the introduction of some automatic testing - thanks to Holger Müller and David Hunt!
As ever, I look forward to hearing all your feedback and suggestions!
New feature: Zooming This release adds the ability to "zoom" on the frequency-based charts: Use your mouse's scroll wheel to zoom in and out - or hold the control button and drag a box on the chart to zoom into.
New chart type: Group Delay Group delay can now be displayed as a chart, and can also be enabled for the marker data display for both S11 and S21.
New chart type: Permeability A new chart, R/ω & X/ω, is available for determining permeability characteristics of toroids. Thanks to David, F4HTQ, for requesting and helping out with this.
Logarithmic Y-scale: The VSWR and Permeability charts now have the option of having the Y-scale shown as Linear or Logarithmic.
Changes to markers:
Time-delay reflectometry:
New scaling function for values: Holger Müller, DG5DBH, contributed new code to show values more correctly, using SI-prefixes. David Hunt provided further changes to avoid losing precision when displaying frequencies for sweep settings.
Also included: Several bug fixes!
As ever, I look forward to hearing about any feedback, suggestions and bugs!
This release, after a short break in the release schedule, offers a few new features and improvements:
Configurable Markers There are a number of new configuration options for markers:
Impedance Analysis The Time Domain Reflectometry window now has a display of an impedance transform, showing the calculated impedance of the transmission line the NanoVNA is looking at from the calibration plane onwards.
New analyses - and automatic running The Analysis window has two new analysis options, peak search and VSWR analysis. It also adds the option to run the analysis automatically whenever new data is acquired, for example for adjusting filters.
Frequency display changed DG5DBH kindly sent me updated functions to display frequencies on GitHub. You can still enter frequencies in the manner you are used to, as Hz, kHz or MHz, but now calculated or read frequencies should more consistently be displayed in a nicely formatted way.
For those running from the Python source, "scipy" is now a required library! Running "pip install ." should fetch it automatically.
Feedback and bug reports are very welcome!
This release adds a number of new features, some bug fixes, and some internal reorganisation:
Adding markers: You can now add or remove markers, allowing you as many as you can fit on your screen. In fact, the software does not stop there: You can even add markers which you can't fit on your screen!
New charts: A number of new chart types have been added, allowing you to plot |Z|, |S11| and |S21| in linear format, S11 and S21 logarithmic on the same chart at the same time, and the raw S11 and S21 real/imaginary S-parameter values.
Calibration updates: The calibration assistant has become more talkative, and should be better at telling you what has gone wrong when it won't apply a calibration. When applying a new calibration, or applying after changing to a different calibration standard set, the previous sweep is immediately updated to show the effect of the new values. This should be useful for finding the right values for calibration standard sets.
Bugfixes: Line thickness and point size should now load correctly and apply to charts after you restart the software. SWR marker colours should similarly also load correctly. The software should now be able to run and attempt to check for updates, and not crash when you don't have an internet connection.
I hope these features and updates are useful to the community!
This release adds a couple of much requested features:
Popout charts All charts can now be popped out as separate windows: Right click them, and select "Popout chart" to get a copy of it. As a side effect of implementing this, the main window can now also contain multiple charts of the same type. Want a zoomed in version of an existing chart next to it? Now you can.
VSWR markers Under Display setup, you now have the option of adding a number of VSWR markers, to be shown on both the S11 Smith chart, the S11 Return Loss chart, and obviously the S11 VSWR chart. The colour can be selected, and you can add however many you need. The markers are saved between startups.
Logarithmic frequency span All frequency-dependent charts can now be changed to show logarithmic frequency span instead of linear. Right click, select Frequency axis, and choose linear or logarithmic.
Shortcuts You can now start a new sweep by pressing Ctrl-W, or stop a sweep by pressing Escape while within the main window.
Line thickness and point size Line thickness and point size can now be configured within the Display setup window. Default values are 1 pixel for lines, 2 pixels for data points.
Additionally, there are minor changes, such as -60 dB points being automatically estimated from -10 dB and -20 dB points when doing filter analysis, and a number of bugfixes and stability improvements.
I look forward to hearing your feedback on the software, and I hope you enjoy using it!
