Chip Rates, Code Layers, and Symbol Rates

To successfully demodulate W-CDMA signals, the analyzer's chip rate must match
the chip rate of your W-CDMA signal. The chip rate determines which code layer is
assigned to each symbol rate , as shown in the following table.
Note
Selecting the ch1 + j*ch2 receiver (the I component is input on channel 1; the Q
component on channel 2) doubles the maximum chip rate .
