Walsh Code Length - CDP Layer (1xEV-DO)
1xEV-DO Standard Setups/Presets Table.)
32 for ForwardLink and 16 for ReverseLink (See: 4 to 128 (ForwardLink) and 2 to 32 (ReverseLink)
selects the active code domain layer (Walsh code length) for the code domain power CDP Layer and CDE Layer trace data results. Available choices depend upon the link Direction, Analysis Channel and CDP Channel type.
This parameter has no other effect except for the display of the CDP Layer and CDE Layer trace data.
