2.4.1.8 I/Q Modulator ("I/Q Mod" Blocks)
The "I/Q Mod" blocks represent the I/Q modulators.
These functional blocks are the access point to:
●
The I/Q modulation of the internal baseband signal
●
The I/Q modulation of an external analog wideband signal (single ended or differ-
ential)
●
The analog I/Q impairments
2.4.1.9 Analog I/Q Output ("I/Q Analog" Blocks)
The "I/Q Output" 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
2.4.1.10 RF and Analog Modulations ("RF" Blocks)
The "RF" block represents the RF settings of the instrument.
This block is the access point to:
●
RF frequency and level settings, as well as the reference frequency, local oscilla-
tor, user correction, etc.
●
The analog modulations
●
The list and sweep modes
2.4.2 Applications Examples of the R&S SMW
Due to its modular design, the R&S SMW can be optimally adapted to the require-
ments of different applications:
●
Generation of digitally modulated signal
The main field of application of the R&S SMW is the generation of digitally modula-
ted signals. The R&S SMW generates a digitally modulated signal in several ways:
using the internal baseband generator, using the externally applied digital base-
band signals or in an analog wideband I/Q operation.
●
Generation of test signals for diversity tests and MIMO scenarios
The R&S SMW enables you to generate test signals in versatile MIMO configura-
tion for which several signal generators were previously required.
●
Generation of a wanted signal and an interfering signal for receiver tests
●
Addition of real-time signals of different standards, for example EUTRA/LTE and
3GPP FDD
