Analysis: Averaged W.F. level vs W.F. level


An averaged graph of levels on one waveform versus the corresponding levels on another waveform is displayed. The X-axis waveform is selected by the "Amplitude W.F. #", and the Y-axis waveform is selected by the "Second ampl. W.F. #". The parameters "W.F. amplitude delay" and "W.F. amplitude window" indicate a range of points, relative to the point where each Y-axis waveform sample occurs, used to obtain the corresponding level reading on the X-axis waveform. The parameters "Min W.F. amplitude" and "Max W.F. amplitude" can restrict the voltage levels allowed on the X-axis to a smaller range. Similarly, the parameters "Second min W.F. ampl." and "Second max W.F. ampl." restrict the Y-axis. Only points whose X and Y axis level readings stay within their respective bounds will be included in the graph.

Unlike the raw W.F. level X-Y graph, the range of voltage levels for the X-axis is divided into a number of bins, and all Y-axis levels are added into these bins to obtain an average curve which is displayed. 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.
