MIMO Channel Matrix (802.11n/ac/ax/be)
is only available for multiple channel measurements.
shows the linear average over all subcarriers of the for each available channel/stream. Each value in the table is a complex value (displayed in real + j*imag format). The is used to look at the spatial spreading done by the transmitter.
This trace is not averaged even when averaging is enabled.
