Despread Syms/Errs (W-CDMA(3GPP)/HSPA)

Menu Path: Trace > Data > Despread 1 > Syms/Errs

When W-CDMA(3GPP)/HSPA Demodulation is enabled, selecting Syms/Errs trace data shows the channel symbol table. The symbol table provides the signal quality error information and the binary bits for each symbol for the specified Code Channel and code layer (Spread Code Length). The bottom half of the display shows the symbol data bits and the upper half shows the error summary data.

For more information see the following topics:

• About the Channel Symbol Table

• About Channel Error Summary Data

• Available Channel Error Summary Data

There is also composite error summary trace data (Trace > Data > Antenna 1 Comp > Error Summary), which provides the signal quality error summary information for the composite signal. (See About Composite Error Summary Data)
