Channel/Layer Tab (1xEV-DO)

The Channel/Layer tab of the 1xEV-DO Demod Properties dialog box provides the parameters to select specific code layers and code channels for the Despread Channel and CDP Layer trace data results.

Despread Channel parameters: Despread Channel parameters specify the code channel and layer used for the reverse link direction channel trace data results including: Chan Error Vector, Chan IQ Meas Time, Chan IQ Ref Time, Chan Mag Error, Chan Phase Error and Chan Syms/Errs trace data:

Walsh Code Length (ReverseLink Direction only)
Walsh Code Number (ReverseLink Direction only)
IQ branch option buttons (ReverseLink Direction only)

CDP Layer parameters: CDP Layer parameters are used to specify the active (displayed) code domain layer for the Code Domain Power (CDP) Layer and Code Domain Error (CDE) Layer trace data. The selected Analysis Channel and Direction limits the available CDP Layers (see About CDP trace data).

Walsh Code Length

Active Channel Detection parameters: These parameters specify how the active code channels are determined for a measurement (see Active Channel Detection):
