CDE Layer (TD-SCDMA)

CDE Layer shows the Code Domain Error (CDE) value for each code channel within the specified sub-frame, timeslot, and code layer (Spread Code Length). The CDE of a particular code channel is a measure of the error power in a code channel relative to the total signal power.

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 (Code Length) for a given code layer (Spread Code Length). The colors are also user definable (see Display Preferences > Color tab).

Selecting a Code Layer

Select the desired code layer by selecting a Spread Code Length from the CDP LayerSpread Code Length drop down list (MeasSetup > TD-SCDMA Demod Properties > Channel/Layer tab).
