Top row:
The section Module contains radio buttons for setting up the parameters:
      Gain - Select the signal / wave pre-amplification.
      Samples FFT - Select the sample length of consecutive data points for the FFT analysis.
      Samples DNL - Select the non consecutive size of data points for a DNL analysis.
      Input Span Compression - Feature of modules TEI0015 and TEI0023, which reduces ADC reference voltage to 0.8.
      High-Z Mode - Feature of modules TEI0015 and TEI0023, which reduces ADC current consumption.
The section Generator controls the square wave generator.
The section Help contains links to the product page of every module and information about the program.

Bottom row:
      Connect - Connects via UART / Serial connection to the module.
      Disconnect - Terminates the connection to a module.

The following buttons are only enabled when a connection is established and after an analysis has been performed. During an analysis these buttons are disabled.

      Wave / FFT - Triggers a FFT analysis according to the parameters set in the section Module.
      Save wave to C:\temp\capture.txt - Available after a FFT analysis, saves the measured ADC values of the previous FFT analysis. The values are stored as integers in a text-file at c:\temp\capture.txt . The folder needs to created manually.
      Start / Stop DNL - Begins a DNL / INL analysis according to the parameters set in the section Module. When pressed during an analysis it terminates the analysis.
      Save DNL histogramm to c:\temp\histogram.txt - Saves the histogram values of a previous DNL analysis. The values are stored as integers in a text-file at c:\temp\histogram.txt . The folder needs to created manually.
      Switch graphs FFT / DNL - Switches between the different sets of graphs for FFT and DNL analysis.
