2.2.5
Connecting Multiple R&S
TSMEs to one Host PC (LTE MIMO Set-
ups, Parallel Usage)
In some cases it is useful to connect more than one R&S
TSME to the same host PC.
In particular, the following measurement scenarios require this setup:
●
LTE MIMO setups
●
Using two R&S
TSMEs in parallel
Due to the compatibility of R&S TSME and R&S TSME6, the combined usage of R&S
TSME and R&S TSME6 devices in an LTE-MIMO setup is possible.
2.2.5.1
Using Two R&S
TSMEs in Parallel
Using two R&S
TSMEs in parallel enhances the measurement capability compared to
a single R&S
TSME, and can increase measurement speed.
A R&S
TSME intelligently captures signals of multiple technologies at the same time, if
they fall within its 20
MHz frontend.
If two R&S
TSMEs are connected, and a technology option is installed on at least one
of the R&S
TSMEs, the measurement software can perform measurements on both
R&S
TSME frontends. Thus you can create a virtual 40
MHz frontend.
Therefore, performing measurements on combined R&S
TSMEs is faster than perform-
ing them on separate R&S
TSMEs in shared spectrum networks.
Using two R&S
TSMEs in parallel requires the following options:
●
A band option (R&S
TSME-KxB) on each R&S
TSME
●
Identical technology options on both R&S
TSMEs to perform measurements on
both R&S
TSME frontends simultaneously
