5.4 Frequency Response Correction
Frequency response correction is a method, used to compensate the frequency
response influence of the test setup, for example of the cables, power combiners,
switches or mixers. In the R&S SMW, you can load user-defined scattering parameters
(S-parameters) files and frequency response files and pre-process the infernally gener-
ated baseband signal with them.

5.5 Applying Digital Predistortion
Digital predistortion (DPD) is one of the methods, used to improve the efficiency of RF
power amplifiers. In the R&S SMW, the generated digital signal can be deliberately
AM/AM and AM/PM predistorted.
