    ● Generation of digitally modulated signal The main field of application of the R&S SMW200A is the generation of digi- tally modulated signals. The R&S SMW200A generates a digitally modulated signal in several ways: using the internal baseband generator, using the exter- nally applied digital baseband signals or in an analog wideband I/Q operation.
