Chan Trace Data (cdma2000/1xEV-DV)

Chan trace data selects time domain trace data for the specified code channel (Walsh Code Number) and code layer (Walsh Code Length). This includes both time domain IQ trace data and Symbol/Error table data.

For cdma2000/1xEV-DV reverse link, the "I" and "Q" branches are logically separate signals. All channel trace data results contain both I and Q branch data, except symbol table trace data. The symbol table contains either the "I" or the "Q" bits as specified by the I/Q branch parameter.

Specify the code channel in the Despread Channel Walsh Code Number drop down list and the code layer in the Despread Channel Walsh Code Length drop down list (click MeasSetup > cdma2000/1xEV-DV Demod Properties > Channel/Layer tab).

Use the Copy Mkr to Despread Chan marker feature to automatically enter the Walsh Code Length and Walsh Code Number information.
