3.6 Using the Arbitrary Waveform Generator (ARB)
The Arbitrary Waveform Generator (ARB) is an I/Q modulation source forming part of
the R&S SMBV100B. The ARB allows the playback and output of any externally calcu-
lated modulation signals in the form of waveform files. The ARB can also generate
multi-carrier or multi-segment signals from the waveform files.
3.6.1 Required Options
The equipment layout for processing of waveform files includes:
●
Base unit, incl. arbitrary waveform generator
●
Corresponding digital standard option (R&S SMBVB-K2xx/K4xx)
Required to process a waveform file generated by the signal generation software
R&S WinIQSIM2.
For example, if you purchase option Digital Standard EUTRA/LTE R&S SMBVB-
K255, you can process EUTRA/LTE waveform files generated by R&S WinIQSIM2.

Pulse Sequencer option
●
Optional, ARB memory extension (R&S SMBVB-K511/-K512/-K513)
Depending on the connectors at that the waveform is output, the following options are
required:
●
Output at the RF connector requires suitable RF frequency option (R&S SMBVB-
B103/KB106)
