Chan IQ Mag Error and IQ Phase Error (TD-SCDMA)

Menu Path: Trace > Data > Channel 1 Chan > IQ Mag Error
Trace > Data > Channel 1 Chan > IQ Phase Error

When TD-SCDMA Demodulation is selected, the Chan IQ Mag Error and Chan IQPhase Error trace data show the vector error between the I/Q measured and the I/Q reference trace data at the sampled symbol times for the specified code channel and code layer (Spread Code Length).

Chan IQ Mag Error trace data shows the magnitude error and Chan IQ Phase Error trace data shows the phase error for the specified code channel.

Selecting the Code Channel and Code Layer

Select the code channel with the Despread Channel Code Channel text box (MeasSetup > TD-SCDMA Demod Properties > Channel/Layer tab). Select the code layer with the Despread Channel Spread Code Length drop down list (MeasSetup > TD-SCDMA Demod Properties > Channel/Layer tab).

Concepts

This trace data is determined just like it is for the IQ Mag Error and IQ Phase Error trace data for Digital Demodulation, see IQ Mag Error and IQ Phase Error (Digital Demod) trace data.
