Wideband baseband characteristics
Internal baseband characteristics (R&S
®
SMW-B13XT option)
The R&S
®
SMW-B13XT provides I/Q paths that can be routed to the installed RF paths or to the analog I/Q outputs. Up to two signals
can be output at the same time, for example:
• Signal A is routed to RF path A, signal B to RF path B
• Signal A is routed to RF path A, signal B to analog I/Q out 1

I/Q impairments (digital baseband)
These impairments are set in the digital baseband section of the R&S
®
SMW200A. They
act on the I/Q signal sent to the I/Q modulator/RF section, as well as on the I/Q signals
at the analog or digital I/Q outputs (of the respective path).

Wideband differential analog I/Q outputs (R&S
®
SMW-K17 option)
This option can be installed once if the instrument is equipped with the R&S
®
SMW-B13XT option. Differential analog I/Q outputs can
be used on signal path A only. If the differential output mode is activated, analog I/Q outputs for signal path B are not available.
