Input interface for the external digital baseband signal
The available interrfaces depend on the installed options:
●
Standard baseband (R&S SMW-B10)
As shown in Table 4-3, the instrument is equipped with up to four digital interfa-
ces (DIG I/Q), the CODER x and the FADER x connectors, that can be used as
input for digital signals.
●
Wideband baseband (R&S SMW-B9)
Provides two digital interfaces (DIG I/Q or CODER x) and two additional high-
speed digital interfaces (HS DIG I/Q or HS CODER x), that can be used in the
same way.
Digital interface may not be enabled in a particular system configuration
(R&S SMW-B9)
The DIG I/Q and the HS DIG I/Q are physically available, but may not be enabled in a
particular system configuration. Refer to Chapter 4.3.4, "Supported Digital Interfaces
Depending on the System Configuration", on page 119 for information on whether and
which of the digital interfaces can be used.
The DIG I/Q digital interfaces provide direct communication with other
Rohde & Schwarz instruments, like:
●
Signal generators
●
R&S EX-IQ-BOX external digital signal interface module
●
R&S FSW signal and spectrum analyzer in radar echo generation applications
●
R&S IQW wideband I/Q data recorder
●
R&S CMW500 radiocommunication tester in fading applications.
