Channel IQ Mag Error and IQ Phase Error (cdma2000/1xEV-DV)

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

When cdma2000/1xEV-DV demodulation is selected, the Chan IQ Mag Error and Chan IQ Phase Error trace show the vector error between the I/Q measured and the I/Q reference trace data at the sampled chip times for the specified code channel (Walsh Code Number) and code layer (Walsh 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 (Walsh Code Number).

Selecting the Code Channel and Code Layer

Select the code channel with the Despread Channel   Walsh Code Number text box (MeasSetup > cdma2000/1xEV-DV Demod Properties > Channel/Layer tab). Select the code layer with the Despread Channel Walsh Code Length drop down list (MeasSetup > cdma2000/1xEV-DV Demod Properties > Channel/Layer tab).

Concepts

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