SMCV100B

Getting Started 1432.7046.02 ─ 04
Equipped with option R&S
SMCVB-K19, the R&S
SMCV100B is able to receive
digital baseband signals and to output digital baseband signals. You can use both
interfaces in parallel: Dig. IQ HS 1 is input and Dig. IQ HS 2 is output of the digital
baseband signals.
The digital baseband inputs and outputs can be used together with other
Rohde
&
Schwarz instruments, like signal generators. A Rohde
&
Schwarz signal
generator for instance can serve as digital signal source in test configuration
requiring two baseband sources.
The "BB Input" block is the access point to the settings of:
●
The external digital I/Q signals
The external digital I/Q signals are further processed in the baseband section.
●
The baseband offsets function
The external and internal baseband signals can be shifted in frequency and
phase.
The "I/Q Digital" block is the access point to the settings of the digital I/Q output
signals.

Additional white gaussian noise ("AWGN"
block)
The "AWGN" block is displayed only in instruments equipped with the option
R&S
SMCVB-K62. This block controls the additional white Gaussian noise gener-
ator (AWGN). An additive white noise is required for measurements of mobile
radio base stations.
7.6
"I/Q stream mapper" block
As one of the access points to the system configuration settings, the "I/Q Stream
Mapper" provides direct access for mapping the generated I/Q streams to the
available output connectors. That is, to the RF 50
Ω
output connector and to the
Dig. IQ HS 2 output connectors.
