pteroDAQtyl 1.1 is released
Version 1.1 of pteroDAQtyl brings windowing functions to the spectrum view, as well as bug fixes that improve the spectrum stability.
Previously, pteroDAQtyl used a rectangular window when estimating power spectral density. pteroDAQtyl 1.1.0 uses a Hann window by default, and gives the option for Rectangle, Hann, Blackman, or Nuttall windows to be used. These new windows are useful when visualizing a small signal near in frequency to a larger signal, and reduce the spectral leakage of the large signal which can obscure the signal of interest.

Changes in version 1.1.1¶
- Add windowing functions to spectrum view. Default window is Hann. Use Rectangle for old windowing behavior
- Spectrum by default has navg=2 instead of navg=1
- Upgrade backend dependencies to QtQuick 5.15.2 and VisualStudio 2019, which may improve performance
- Improved PWM control. For example, duty cycle stays constant when adjusting PWM frequency
- Improved stability of spectrum display
Changes in version 1.0.0¶
- Added trigger arm time feature. Arm time improves performance with noisy trigger signals by requiring the signal to entire the untriggered for some duration before triggering can occur.
- Added high pass filter
- Improved support for DPD80 Balanced Photodetectors
- Changed default filter when downsampling to FIR filter which typically displays improved downsampling performance
- Fixed bug with oscilloscope rendering with large number of data points
- Fixed bug when spectrums saved as .txt files
- Additionally bug fixes and stability improvements
- Built with Qt 5.13.2 for improved UI performance
