Comp Error Vector Time (1xEVDO)

When 1xEV-DO Demodulation is enabled, the Comp Error Vector Time trace data is the error-vector, time-domain data for the composite signal.

Composite, forward link, trace data results are computed from the first measured slot. Composite, reverse link, trace data results are computed from the first measured half (0.5) slot. The and parameters have no effect on this measurement.

Concept Information

This trace data is identical to the Channel Error Vector Time trace data except that the source data is the composite signal. See Chan Error Vector Time trace data for concept information.

For forward link measurements, the segment of the signal included in the trace data depends on the Analysis Channel and Combine TDM channels for composite results parameter settings.

For forward link measurements, the trace background annotation indicates what segment of the 1xEV-DO frame is being analyzed. Change the trace display colors from the Display Preferences > Color tab.
