Estimate IQ Mismatch Per Subcarrier (802.11n/ac/ax/be)
creates a frequency-selective IQ impairment estimation.
When selected, the estimated IQ mismatch data is shown in the OFDM IQ Gain Imbalance Per Subcarrier and OFDM IQ Quad Error Per Subcarrier traces. Per-user IQ Gain Imbalance and IQ Quadrature Error are shown in the OFDM Multi-User Info table for multi-user measurements.
(default) IQ mismatch per subcarrier is not estimated. When cleared, NO DATA appears in the OFDM IQ Gain Imbalance Per Subcarrier and OFDM IQ Quad Error Per Subcarrier traces, and "***" appears in the GainImb(dB) and QuadErr(deg) columns of the OFDM Multi-User Info table.
Estimate IQ Mismatch Per Subcarrier is only recommended when the result length is set longer than 3 symbols. When the result length is less than 3, demodulation results may not be accurate.
