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
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
to use the function Generate Waveform"
–
With the "Create ARB Test Signal" function, see
ate and save ARB test signals"
●
Externally, for example:
–
With the free of charge software R&S WinIQSIM2, see
to use waveform files with R&S
–
With the software R&S
ARB
Toolbox
–
Calculated using a mathematical program such as MATLAB, see
ter 4.6.4.5, "How to manually create a waveform using tag file format"
Provided the R&S
SMM100A 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.

How to create and save ARB test signals
If your test case requires a simple sine or square test file, consider to use the provided
ARB test signals.
To generate a sine test signal
1. Select "Baseband > ARB"
2. Select "Create Test Signal > Sine".
3. Adjust the "Sine Test Signal" settings as required.
4. Select "Generate Signal File".
A standard file-select dialog opens.
a) Navigate to the directory, in that you want to save the file, e.g. /var/user/.
b) Enter a filename (e.g.
sine_waveform
).
c) Click "Save".
The R&S
SMM100A saves the generated waveform file and automatically loads it
in the ARB.
Using the arbitrary waveform generator (ARB)
