Displacements measured for each frame, on the trace selected by the "Amplitude trace #", are displayed with respect to corresponding level measurements on the waveform selected by the "Amplitude W.F. #". The trace amplitude measurements are taken the same way they are for the "Raw trace amplitude vs step cycle" graph. The waveform amplitude measurements are taken the same way they are for the "Trace averaging based on W.F. level" analysis. The range of voltage levels measured from the selected waveform is divided evenly into a number of bins, and all displacements are added into these bins to obtain an average curve which is displayed.
Deleted frames, and frames whose tag values are not in the "Tag list" are excluded. You can also exclude frames that occur during the inactive phase of cycles, or the active phase, in the same way as for the "Trace averaging based on W.F. level" analysis, using the "Active cycle phase only" option.
The "Fixed W.F. level bins" option has the same effect here as it does for the "Trace averaging based on W.F. level" analysis, causing the "Min W.F. amplitude" and "Max W.F. amplitude" to define a fixed range which is divided into bins, even if it exceeds the range of levels in the waveform.
