There are two ways of upgrading Signal Generator SMIQ [1] to a source for W-CDMA (wideband code division multiple access) signals. One way involves using Modulation Generator AMIQ [2] to provide the necessary W-CDMA baseband signals for SMIQ. In this case the unit is operated via a convenient menu in Software WinIQSIM [3]. The other way is through W-CDMA option SMIQB43, which is now available and makes SMIQ a stand-alone W-CDMA source. The well-proven options Data Generator SMIQB10 and Modulation Coder SMIQB11 are used to generate the baseband signals.
