CDP Layer (cdma2000/1xEV-DV)

CDP Layer trace shows the measured channel power for all code channels (Walsh Code Number) within the specified code layer (Walsh Code Length). If the Measurement Interval is greater than one, all PCGs within the Measurement Interval are averaged together to produce the CDP Layer results.

Display Format

The data is shown in a multi-color format that assigns a unique color to each code layer and related active code channels. This makes it easy to visually identify and distinguish the active code channels (Walsh Code Number) for a given code layer (Walsh Code Length). The colors are also user definable (see Display Preferences > Color tab).

For CDP and CDE trace data displays with separate I/Q channel trace bars, to position the Marker to the desired Code Layer/Channel bar, click in close proximity to the horizontal bar that indicates the value of the code channel being measured.

Selecting a Code Layer

Select the desired code layer by entering the Walsh Code Length in the CDP Layer Walsh Code Length text box (MeasSetup > cdma2000/1xEV-DV Demod Properties > Channel/Layer tab).
