Channel 1 CDP Trace Data (TD-SCDMA)

Menu Path: Trace > Data > Channel 1 CDP

CDP (Code Domain Power) and CDE (Code Domain Error) trace data results for either the composite signal or for a specified code layer. Code Domain Power (CDP) is an analysis of the distribution of signal power across the set of code channels normalized to the total signal power.

• CDP Composite Trace Data: This is the CDP (Code Domain Power) and CDE (Code Domain Error) trace data results for the composite signal. Composite trace data results are derived from data for the total signal. This includes the combined data from all Spread Code Length (or Symbol Rates) and Code Numbers.

• CDP Layer Trace Data: This is the CDP (Code Domain Power) and CDE (Code Domain Error) trace data results for a specified code layer. Use the CDP Layer Spread Code Length drop down list to specify the Code Layer (MeasSetup > TD-SCDMA Demod Properties> Channel/Layer tab).

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