Figure 6.35: Select Signal Window
Pressing Next again leads to the next step, the Result Style dialog (see Figure
6.36). Here the way data is shown on the screen is selected. Usually this is
identical to selecting the units of the diagram axes. For time signals choose
between a binary, linear representation, in which the input signals are always
scaled to [-32768 ... +32767], or a dB FS (full scale) scale.
Note:
Independent of the input data format, samples are always
converted to 16bit/sample. This means that 8bit/sample data are
multiplied by 256 before they are processed any further.
