3.6.4 How to Create, 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 3.6.3, "ARB Set-
tings" , on page 150.
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 3.6.4.2, "How
to Create Waveform Files with the Built-In Generate Waveform File Function" ,
on page 161
– With the "Create ARB Test Signal" function, see Chapter 3.6.4.1, "How to Cre-
ate and Store ARB Test Signals" , on page 160
●
Externally, for example:
–
With the free of charge software R&S WinIQSIM2, see Chapter 3.6.4.4, "How
to Create a Waveform File with the R&S WinIQSIM2 and Load it in the ARB" ,
on page 162
– With the software R&S ARB Toolbox
– With the R&S SMBVB-K300/-K301 Pulse Sequencer software
– Calculated using a mathematical program such as MATLAB, see Chap-
ter 3.6.4.5, "How to Manually Create a Waveform Using Tag File Format" ,
on page 167.
Provided the R&S SMBV100B is equipped with the required option, you can load this
waveform 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.
3.6.4.1 How to Create and Store ARB Test Signals
If your test case requires a simple sine or square test file, consider to use the provided
ARB test signals.
1. Select "Baseband > ARB"
2. Select "Create Test Signal > Sine".
3. Adjust the "Sine Test Signal" settings as required.
4. Select "Generate Signal File".
Navigate through the directory tree (e.g.
/var/user/
).
Enter a filename (e.g.
sine_waveform
).
Select "Save".
The R&S SMBV100B stores the generated waveform file and automatically loads it
in the ARB.
