Version history

27/06/2022 Version 1.81
- Changed meaning of 'smooth' (iron icon) on Live Measurements: now it's smooths measurements (not curves); available on Smith tab; it is applied when exporting data
- Fixed certificate issue on Windows
- Added few built-in Calibration Kits
- Added pre-definition of agilent 85033D calibration kit
- Fixed issue with missing file extension after file open dialog on Raspberry (and some Linuxes)
- Fixed crashes when loading some old project file formats

20/05/2022 Version 1.78
- Added export settings (domain, modes, columns) for CSV file for Live Measurements and XYY windows.
- Added zipping for calibration files (now calibration file is zipped old calibration file; old are still loadable)
- Fixed few bugs on Mac-OS with storing files
- Made it possible to use a set of touchstone files as a Calibration Kit
- Added plot settings for Live Measurements. Plus side buttons to control plot scale
- Fixed API crush when connecting to some devices through VCI interface

27/1/2022 Version 1.69
- Added explicit Signal Generator Tool dialog
- Fixed few issues in appearance
