4.7.4 How to Generate and Play Waveform Files
This section provides step-by-step instructions on configuring and using the provided
settings. For details on individual functions and settings, see Chapter 4.7.3, "ARB Set-
tings", on page 305.
Some test cases do not require a real time generation of signal according to a digital
standard. For these test cases, the replay of a previously generated waveform is suffi-
cient. In such cases, you can generate the required test waveform file in one of the fol-
lowing ways:
●
Internally,
– With the built-in "Generate Waveform File" function, see Chapter 4.7.4.2, "How
to Create Waveform Files with the Built-In "Generate Waveform File" Function",
on page 317
– With the "Create ARB Test Signal" function, see Chapter 4.7.4.1, "How to Cre-
ate and Store ARB Test Signals", on page 316
●
Externally, for example:
– With the free of charge software R&S WinIQSIM2, see Chapter 4.7.4.4, "How
to Create a Waveform File Generated with the R&S WinIQSIM2 and Load it in
the ARB", on page 318
– With the software R&S ARB Toolbox
– With the R&S SMW-K300/-K301 Pulse Sequencer software
– Calculated using a mathematical program such as MATLAB, see "How to Man-
ually Create a Waveform Using Tag File Format" on page 975.
Provided the R&S SMW is equipped with the required option, you can load this wave-
form file and subsequent process it with the instrument.
This section provides examples on the internal waveform file generation and on the
external generation with the R&S WinIQSIM2.

If your test case requires a simple sine or square test file, consider to use the provided
ARB test signals.
