Relative Constellation Error in trigger-based PPDU > max power of MCS7
This parameter is available when Radio Std is 802.11ax or 802.11be.
Specifies RMS EVM limits in a list of 18/15 elements for a HE/EHT trigger-based
PPDU (dB) when its transmit power is greater than the maximum power of MCS7
(dB).
