Analysis: Averaged trace amplitude vs trace amplitude

Home › Software › Analysis Help › Methods › Averaged trace amplitude vs trace amplitude


An averaged graph of displacements measured on one trace, for each frame, versus the displacements on another trace for these frames is displayed. The X-axis trace is selected by the "Amplitude trace #", and the Y-axis trace is selected by the "Second ampl. trace #". The range of voltage displacements for the X-axis is divided evenly into a number of bins, and all Y-axis displacements are added into these bins to obtain an average curve which is displayed.

The trace amplitude measurements for the X-axis are taken the same way they are for the "Raw trace amplitude vs step cycle" graph. Deleted frames, and frames whose tag values are not in the "Tag list" are excluded.

The trace amplitude measurements for the Y-axis are taken in a very similar way. The position of the two points in the frame's window are selected by the parameters "Second trace ampl. point" and "Second trace ampl. ref". These two parameters have corresponding "window" parameters, which can be used to select two ranges of points in the frame's window; the action taken in these ranges is determined by the parameters "Find second max trace ampl.", "Average second trace ampl. ref." and "Second trace ampl. integration".
