3. In the file selection dialog, select the filename and storage location of the settings
file.
The settings are restored, but the frequency and level settings are retained; you
can repeat the signal generation with the same settings.

How to recall the settings of a firmware option
Some test setups, e.g. for MIMO tests, require that two or more instruments generate
baseband signal with similar settings. One easy way to speed up the configuration is to
use the dedicated save/recall function to transfer the configuration data from one
instrument to the other.
To use the "Save/Recall" function to transfer settings related to a digital stan-
dard to another instrument
1. In the first instrument, select "Baseband > Digital Standard, e.g. 3GPP FDD".
Adjust the settings as required.
2. In the "3GPP FDD > General" tab, select "Save".
In the file selection dialog, select a filename and storage location for the settings
file.
A file with the defined name and path and a predefined extension (
*.3g
) is cre-
ated.
3. Connect both instrument to a LAN.
Alternatively, use a USB flash drive to transfer the created
*.3g
file to the second
instrument.
4. In the second instrument, select "Baseband > 3GPP FDD > General > Recall" to
load the saved file.
5. Navigate in the file selection dialog. Select the filename and storage location of the
settings file.
The settings are loaded in the second instrument. If the corresponding settings are
left unchanged, the second instrument generates a signal with identical baseband
settings.

Accessing files with user data
By the calculation of signals according to the different digital standards or by the gener-
ation of custom digitally modulated signals, the R&S
SMM100A uses the data from dif-
ferent data sources (see also
Chapter 4.4.1.1, "Data, clock and control signals and
on page 88). To simulate the signal of one UE for instance,
the instrument modulates and codes the provided data for each channel. It further pro-
cesses the signal as described in the corresponding standard.
