5. Select "ARB > State > On".
The R&S SMBV100B processes the waveform file.
3.6.4.2 How to Create Waveform Files with the Built-In Generate Waveform File Function
Several digital standards provide the special function "Generate Waveform File". This
function enables the calculation and storage of the signal as a waveform file that can
be afterwards played by the ARB generator.
To generate an EUTRA/LTE waveform file
1. Select "Baseband > EUTRA/LTE/IoT..."
2. Adjust the settings as required, for example:
a) select "Link Direction > Downlink"
b) select a predefined test model, "Test Setups/Models > E-TM1_1__10MHz"
3. Enable "EUTRA/LTE/IoT > State > On".
4. Select "Generate Waveform File".
Navigate through the directory tree (e.g.
/var/user/
).
Enter a filename (e.g.
lte_waveform
) .
Select "Save"
The R&S SMBV100B stores the generated waveform file
lte_waveform.wv
under the selected directory
/var/user/
.
To process the waveform file, load it in the ARB (see Chapter 3.6.4.3, "How to
Load and Play Waveform Files" , on page 161).
3.6.4.3 How to Load and Play Waveform Files
Irrespectively on the way a waveform file is generated, you can transfer it on the instru-
ment, load it in the ARB and play it.
To load and play a waveform file
1. Transfer an externally created waveform file to the instrument.
See Chapter 9.9, "How to Transfer Files from and to the Instrument" , on page 497
2. Select "Baseband > ARB"
3. Select "Load Waveform File".
Navigate to the directory with the stored file.
Select the waveform file (e.g.
/var/user/lte_waveform
).
Press "Select".
The "ARB" dialog confirms that the waveform file is loaded.
4. Select "ARB > State > On".
The R&S SMBV100B processes the waveform file.
