What works:

• generator
• spectrum analyzer
• oscilloscope
• frequency response - just frequency stepping

Operating systems: Linux, Windows, MacOS

Dependencies

• wxWidgets 3.0.x (https://www.wxwidgets.org/)
• RtAudio 5.1 (https://github.com/thestk/rtaudio)
• libfccp (https://github.com/ben-strasser/fast-cpp-csv-parser)
• CMake 3.x (https://cmake.org)

ToDo

General

• extend OscopeCtrl to add more traces
• extend OscopeCtrl to add zooming of waves
• load/save of config

Generator

• white noise

Oscilloscope

• changeable length of buffer - problem with "slower" Xscale
• peak-to-peak measurement

Spectrum Analyzer

• better Y-scaling of spectrum analyzer
• averaging in spectrum analyzer
• add switch between CH1 and CH2 ( left/right)

Frequency Response

• finish input peak value measurement
• add trace selector
• support load/save measurements, for example as XML/CVS/JSON/IEC 60076-18 1.0/MLSSA/FRD File Format.
• save pictures of measurement graph
