Function

Allows you to see the waveform file with respect to the entire dynamic range of the A/D converter. Activating this function modifies the vertical scale (and automatically adjusts the waveform) so the + and - full scale counts are placed at the top and bottom of the waveform strip.

An A/D converter operates in terms of counts. If X represents the resolution of the A/D converter, then the + full scale limit is [2(x-1)-1] counts and the - full scale limit is 2(x-1) counts. For example if you have a 12-bit A/D converter, the + full scale limit is 2047 counts and the - full scale limit is 2048 counts.

Activating Procedure

    In the Scaling menu click on Show Dynamic Range.

   Choose Scaling Show Dynamic Range (ALT, C, R).

This modifies the vertical scale (and automatically adjusts the waveform) to place the + and - full scale A/D converter counts at the top and bottom of the waveform strip, thus showing you the waveform file with respect to the entire dynamic range of the A/D converter.

Special Considerations

Subsequent activation's of the Show Dynamic Range command does nothing, the function does not toggle. To get back to the display you had prior to activating the Show Dynamic Range function, use the Undo command on the Edit menu.
