●
The baseband offsets function
Signals from the baseband generator can be shifted in frequency and phase, or
boosted in power.
2.4.4 Digital Baseband Input ("BB Input"Block)
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,
or boosted in power.
2.4.5 Additional White Gaussian Noise ("AWGN" Block)
The "AWGN" block is displayed only in instruments equipped with the option
R&S SMBVB-K62. This block controls the additional white Gaussian noise generator
(AWGN). An additive white noise is required for measurements of mobile radio base
stations.
2.4.6 "I/Q Stream Mapper" Block
As one of the access points to the system configuration settings, the "I/Q Stream Map-
per" provides direct access for mapping the generated I/Q streams to the available out-
put connectors. That is, to the analog RF and I/Q output connectors.
2.4.7 I/Q Modulator ("I/Q Mod" Block)
The "I/Q Mod" block represent the I/Q modulator.
This functional block is the access point to:
●
The I/Q modulation of the internal baseband signal
●
The I/Q modulation of an external single-ended analog wideband signal
●
The analog I/Q impairments
2.4.8 Analog I/Q Output ("I/Q Analog" Block)
The "I/Q Analog" block represents the analog I/Q output connectors.
This block is the access point to the settings of:
●
The analog I/Q output signals
The generated signal can be output as single-ended or differential analog signal.
●
The analog I/Q impairments
