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.
