4.7 Using the Arbitrary Waveform Generator (ARB)
The Arbitrary Waveform Generator (ARB) is an I/Q modulation source forming an inte-
gral part of the R&S SMW. The ARB allows the playback and output of any externally
calculated modulation signals in the form of waveform files. The ARB can also gener-
ate multi-carrier or multi-segment signals from the waveform files.
4.7.1 Required Options
The equipment layout for processing of waveform files includes:
●
Option Standard or Wideband Baseband Generator (R&S SMW-B10/-B9) per sig-
nal path
Arbitrary Waveform Generator is incorporated in the Baseband Generator
●
Option Baseband main module, one/two I/Q paths to RF (R&S SMW-B13/-B13T) or
Option Wideband baseband main module two I/Q paths to RF (R&S SMW-B13XT)
●
Corresponding Digital Standard option (R&S SMW-K2xx) per signal path
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 SMW-
K255, you can process EUTRA/LTE waveform files generated by R&S WinIQSIM2.

Pulse Sequencer option
Depending on the connectors the waveform is output at, the following options are
required:
●
Output at the RF connector requires suitable RF frequency option (R&S SMW-
B1xx/-B2xx)
●
Output at the BBMM connectors requires option Digital Baseband Output
(R&S SMW-K18) per signal path
