Signal Capture
Defines the MIMO method used by the analyzer(s) to capture data from multiple TX
antennas sent by one device under test (DUT).
All modes support RF and Analog Baseband signal input.
"Simultaneous"
Simultaneous normal MIMO operation
The number of Tx antennas set in DUT MIMO configuration defines
the number of analyzers required for this measurement setup.
"Sequential
using OSP
switch"
Sequential using open switch platform
A single analyzer and the Rohde & Schwarz OSP Switch Platform
(with at least one fitted R&S®OSP-B101 option) is required to mea-
sure the number of DUT Tx Antennas as defined in DUT MIMO con-
figuration.
"Sequential
manual"
Sequential using manual operation
A single analyzer is required to measure the number of DUT Tx
Antennas as defined in DUT MIMO configuration. Data capturing is
performed manually via the analyzer's user interface.

Simultaneous Signal Capture Setup
For each RX antenna from which data is to be captured simultaneously, the settings
are configured here.
State ← Simultaneous Signal Capture Setup
Switches the corresponding slave analyzer On or Off. In On state the slave analyzer
captures data. This data is transferred via LAN to the master for analysis of the MIMO
system.
Remote command:
CONFigure:WLAN:ANTMatrix:STATe<RecPath> on page 156
Analyzer IP Address ← Simultaneous Signal Capture Setup
Defines the IP addresses of the slaves connected via LAN to the master.
Remote command:

Assignment ← Simultaneous Signal Capture Setup
Assignment of the expected antenna to an analyzer. For a wired connection the
assignment of the Tx antenna connected to the analyzer is a possibility. For a wired
connection and Direct Spatial Mapping the Spectrum Flatness traces in the diagonal
contain the useul information, in case the signal transmitted from the antennas
matches with the expected antennas. Otherwise the secondary diagonal will contain
the useful traces.
