Joined RX Sync and Tracking ← Simultaneous Signal Capture Setup
This command configures how PPDU synchronization and tracking is performed for
multiple captured antenna signals.
"ON"
RX antennas are synchronized and tracked together.
"OFF"
RX antennas are synchronized and tracked separately.

Sequential Using OSP Switch Setup
A single analyzer and the Rohde & Schwarz OSP Switch Platform (with at least one
fitted R&S®OSP-B101 option) is required to measure the number of DUT Tx Antennas
as defined in DUT MIMO configuration.
Note: For sequential MIMO measurements the DUT has to transmit identical PPDUs
over time! The signal field, for example, has to be identical for all PPDUs.
This setup requires the analyzer and the OSP switch platform to be connected via
LAN. A connection diagram is shown to assist you in connecting the specified number
of DUT Tx antennas with the analyzer via the Rohde & Schwarz OSP switch platform.
Fig. 4-3: Connection instructions for sequential MIMO using an OSP switch
The diagram shows an R&S®OSP-B101 option fitted in one of the three module slots
at the rear of the OSP switch platform. The DUT Tx antennas, the OSP switching box
and the analyzer have to be connected as indicated in the diagram.
