Although antenna characteristics are set by the respective standard body for most standard models, these commands allow you to customize antenna properties when using a MIMO configuration to better model the actual real world conditions.
Numerical Choices:
FSIMulator[1]|2 – These choices correspond to the Master Setups used in the selected configuration. Only multi-user MIMO uses more than one Master Setup.
RX:ANTenna[1]|2|3|4|5|6|7|8 – Refer to the block diagram for your system configuration to determine the I/O output block that you want to configure.
TX:ANTenna[1]|2|3|4 – Refer to the block diagram for your system configuration to determine the I/O input block that you want to configure.
