OFDM Eq MIMO Cond Number (802.11n/ac/ax/be)
is only available for multiple channel measurements.
This result is a vector containing the "condition number" of the equalizer channel frequency response matrices, one condition number value for each subcarrier. Each equalizer channel frequency response matrix is a 2x2 matrix formed by taking one value from each of the four equalizer channel frequency response traces. Condition number is a standard measure of how ill-conditioned a matrix is.
Condition number is defined as the ratio of the maximum singular value to the minimum singular value of a matrix. The value is always real and always greater than or equal to one. Larger values indicate a more ill-conditioned matrix. If the condition number is larger than the SNR Signal-to-Noise Ratio of the signal, it is likely that MIMO Multiple Input, Multiple Output: A physical layer (PHY) configuration in which both transmitter and receiver use multiple antennas. separation of the multiple data streams will not work correctly.
This result is computed only when there are multiple data streams present.
When there is only one input channel or when the input channels contain only one data stream, the trace is blanked and a "NO DATA" trace indicator is shown.
