14 Multi-Band, Multi-Antenna and Multi-Vehicle
Scenarios
Option: R&S
SMW-K120
With R&S
SMW equipped with R&S
SMW-K120, you can simulate up to two vehicles
and up to four antennas. Moreover, with one single instrument, you can not only gener-
ate a GNSS signal and an interfering signal but also multi-bands GNSS signals. The
latter case refers to GNSS signals transmitted on two different frequency bands.
Depending on the installed options, the generated signal can possibly also consist of
satellites from different GNSS systems.
One further advantage of the advanced mode is that it couples the baseband source to
simplify and speed up configuration. In contrast to traditional case, where each base-
band source has to be configured separately, in the GNSS advanced mode, you con-
figure the whole system at once. Hence, you configure the satellite's constellation once
and it is then imposed on the individual conditions, obscuration or multipath effects of
the multiple vehicles or antennas. The difference in conditions results from the individ-
ual receiver's position, receiver type and antenna pattern.
You only have to select which signals (called steams) are actually output at the RF
connectors.
How to enable the advanced mode
1. On the block diagram, select "System Config > System Configuration > Fading/
Baseband Configuration".
2. Select "Mode > GNSS Advanced".
The preview diagram indicates the configuration and gives information on its com-
mon application fields.
3. Confirm with "Apply" and "OK".
