2.2.5.2 LTE MIMO Setups with Two R&S TSMEs
Basic LTE MIMO measurements are possible with a single R&S TSME, which can ana-
lyze two different transmission paths of a signal from two different transmit antennas. A
single R&S
TSME can determine the RSRP/Q and RS SINR results for both paths (see
documentation of the measurement software for details).
If two R&S TSMEs are connected to one host PC, multiple signals can be received by
two receive antennas and processed in one application. This is useful, for example, to
analyze a MIMO matrix, condition numbers, or ranks, or generally to optimize the LTE
MIMO setup.
Required options
An LTE MIMO measurement setup with two R&S TSMEs requires the following
options :
●
LTE option (R&S TSME-K29) and a band option (R&S TSME-KxB) installed on at
least one R&S TSME in the MIMO setup
●
LTE MIMO option (R&S TSME-K30) installed on at least one R&S TSME in the
MIMO setup
●
MIMO extension option R&S TSME-K300, which is installed at factory by default,
on each R&S TSME
The following table demonstrates the minimum configuration for LTE MIMO measure-
ments.
Table 2-2: Sample (minimum) configuration for LTE MIMO measurements with 2 R&S TSMEs
R&S TSME Option
1 KxB, LTE (K29), LTE MIMO (K30)
2 none (MIMO extension option R&S TSME-K300 installed by default)
Furthermore, the following connections are required for an LTE MIMO setup:
●
Power supply for each R&S TSME, see Chapter 2.2.1, "Connecting the DC Power
Supply" , on page 15
The R&S TSME-ZYC option provides a cable to connect 2 R&S TSMEs to one
power source
●
Synchronization and mechanical connection of two R&S TSMEs using the
R&S TSME-ZC2 option (mandatory)
●
LAN connection between the two R&S TSMEs and the host PC, see Chap-
ter 2.2.5.5, "Configuring the LAN Connections Between Multiple R&S TSMEs Con-
nected to One Host PC" , on page 28
2.2.5.3 LTE MIMO Setups with Four R&S TSMEs
If four R&S TSMEs are connected to one host PC, multiple signals can be received by
four receive antennas and processed in one application. This is useful, for example, to
perform LTE MIMO path measurements or throughput/CQI estimations (in addition to
the results using 2 R&S
TSMEs).
