Comparing Variations

Network Data Explorer can compare variations for neutral format (*.nmf) files or multiple network data sets that are the same size.

1. On the NDE ribbon, click Open.
2. In the Open window, select two or more Neutral Format files or network data files that are the same size and click Open.
3. In the Network Data Selection pane, select the newly opened files.
4. On the NDE ribbon, click Compare Data.
5. In the Cell and Frequency Selection pane, select which ports you want to compare . For each value along the X-axis, the Y-axis values are subtracted, one from the other, to create the comparison plot.

It is not possible to compare a data set against itself unless the data set has been loaded twice.

Traces for a given cell or statistical measure are displayed for all data sets; you can use tool tips to distinguish between them.

If a single cell or statistical measure is displayed, different colors are used for each data trace. If multiple cells or statistical measures are selected, a single color is used for all data traces for each cell or statistical measure.

In a data comparison, traces are shown for all selected data sets. This is true for both cell and statistical traces.

Data sets with no variation information are always displayed. With multiple variation data sets, only those with values for the currently selected variations are displayed.
