Dear Reef,
Thank you again for the Program. I like it so much! I can run it even from my office computer. I can save data in ASCII format and transfer them to Origin, for example.

EWWin 2012 for Windows

EWWIN 2012 is a complete data acquisition solution for your EPR needs. Designed by spectroscopists for spectroscopists, it is in use around the world on all makes and models of EPR spectrometers.

NOW includes EWVOIGT.

Go to:


  • Display data acquisition of current and averaged data in real time for one to four channels
  • Separate data acquisition and data manipulation windows for simultaneous operation
  • File I/O in a variety of data formats (including Bruker)
  • Data manipulation of spectra
    • Add, subtract, multiply, divide by a constant `
    • Copy, duplicate, move
    • Fast Fourier Transform
    • Smooth (Savitsky Golay with any number of points)
    • Integrate, Differentiate, Double Integration
    • Align spectra
    • Spectral Subtraction
    • Baseline Correction (including entering arbitrary baseline correction)
    • Shift in field axis
    • Flatten (for FFT smoothing)
    • FFT Windowing (Parzen, Hanning, Welch, Hamming, Exact)
    • Auto offset (vertical display of data)
    • Power calculation (for determining power saturation)
    • Statistical analysis of noise
    • Line shape analysis (EWVoigt functionality)
  • Setup of data acquisition parameters from independent window

A 14 day fully functional version of EWWIN 2012 can be downloaded. After 14 days, request a free validation code for the basic EWWIN 2012 functions (everything except data acquisition and lineshape analysis).
