    203205Details and examples for the above are provided at the [https://wiki.cosmos-lab.org/wiki/Resources/Services/ArrayMgmt array management page].
    204206For this experiment, we use static array management commands as shown below.
    205 First, start PAAM #1 (rfdev4-in1) in RX mode with V-polarization using 4 antenna elements on IC 0, and configure the RX beamforming direction to be in the broadside (0,0). Check the current consumption on 2v7_0 and make sure IC0 has been successfully initialized (e.g., 2v7_0 has a current consumption much higher than the other ICs).

     207First, start PAAM #1 (rfdev4-in1) in RX mode with V-polarization using 16 antenna elements on all the ICs, and configure the RX beamforming direction to be in the broadside (0,0). Check the current consumption on 2v7_0,1,2,3 to make sure all the ICs have been successfully initialized.
