Rohde & Schwarz R&S

SMW200A Vector Signal Generator 53

Digital baseband inputs/outputs for wideband baseband

Depending on the installed software and hardware options, the R&S

SMW200A is able to receive digital baseband signals and output

digital baseband signals. The digital I/Q input/output can be used for the lossless connection of the R&S

SMW200A to the digital I/Q

input/output of other Rohde & Schwarz instruments.

Digital baseband outputs: At least one R&S

SMW-K19 option must be installed. Digital baseband outputs can be used either on signal

path A or B with one R&S

SMW-K19 option. For digital baseband outputs to be used on signal paths A and B simultaneously,

two R&S

SMW-K19 must be installed. To enable two or more digital baseband outputs in multichannel or other advanced modes,

two R&S

SMW-K19 must be installed.

The R&S

SMW-K19 option requires R&S

SMW-B13XT with DACW board revision 4.00 or higher.
