Channel/Layer Tab (TD-SCDMA)

The Channel/Layer tab of the TD-SCDMA Demod Properties dialog box specifies the Despread Channel (code channel and code layer) parameters and CDP Layer (code layer) parameters used to configure the Channel trace data and CDP trace data displays respectively.

These parameters can be reconfigured to get new trace data results without the need to acquire new data. The new data results are recomputed from the current data record.

Despread Channel parameters: Specifies the timeslot and code channel with spreading factor that is used for the channel measurement data results which include: Chan Error Vector, Chan IQ Meas Time, Chan IQ Ref Time, Chan Mag Error, Chan Phase Error and Chan Syms/Errs trace data (click on the parameter name for further information):
- Spread Code Length (Despread Channel)
- Code Channel (Despread Channel)
CDP Layer parameters: Specifies the active (displayed) code domain layer for the Code Domain Power (CDP) Layer and Code Domain Error (CDE) Layer trace data:
- Spread Code Length (Despread Channel)
Modulation Scheme parameters: Specifies how the modulation type used for demodulation is detected:
- Auto-detect for all code channels
- Manual
The Modulation Scheme parameters are only available when the Enable HSPA/8PSK check box in the Format tab of the TD-SCDMA Demod Properties dialog box is selected.
