2. Select this hardware setup in the "General Settings" sub-dialog of an OTA test tem-
plate. See
​
chapter 3.1.2.1, "Hardware Setup Selection" , on page 24.
3. In the "Loop Settings" sub-dialog, configure the sequence of angular positions to be
accessed during the test. A special extended MIMO version of this sub-dialog is
available, as an additional loop may be defined for the second test antenna. See
​
chapter 3.1.2.5, "Loop Settings" , on page 26.
4. In the "Communication Settings" sub-dialog, configure the radio link as required. Take
special care to select open loop spatial multiplexing as a transmission scheme and
to configure a high-order modulation scheme, typically 64QAM, with a high transport
block size index. See
​
chapter 3.1.2.2, "Communication Settings" , on page 25.
5. In the "Fading Settings" sub-dialog, modify the static channel model of the commu-
nication tester, if desired. See
​
chapter 3.1.2.4, "Fading Settings" , on page 26.
3.1.1 Hardware Setup
In the "Hardware Setup" dialog, you can select the desired test case and call the R&S
CMW500 LTE driver configuration dialog in order to perform basic RF configurations.
Access: "File > Hardware Setup Open/New..." in the R&S AMS32 main dialog window
(keyboard shortcut "Ctrl+H"). In the "Hardware Setup Open" dialog opened, select "New
> OTA Measurements" and click "OK".
The "peak performance test in spatial multiplexing mode" corresponds to the selection
"MIMO 2x2 with variable offset between test antennas" in the "Sensitivity" tab.
