Back From Christmas Update

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!

Advent update

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!

Zoom, zoom, zoom!

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:

• Now able to display Group Delay for S11 and S21
• Markers can be filled or "hollow"
• Markers can be shown centered, or with the point at the tip
• Markers can be locked from mouse control by selecting the radio button next to "Show/Hide data"

Time-delay reflectometry:

• Min/max impedance values can be manually set
• There's a movable marker to measure distance in the TDR chart

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!

Configurable markers and impedance analysis

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:

• The size of the markers can be changed under Display Setup,
• Marker numbers can be displayed in the charts,
• Marker data box headings can be coloured or not, depending on user preference,
• The data displayed for markers is now configurable

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!
