Edit 11ax/be Limit
This page defines the EVMM limit for 11ax/be:
–
"Relative Constellation Error in common" on page 1269
–
"Relative Constellation Error in trigger-based PPDU > max power of MCS7" on
page 1271
–
"Relative Constellation Error in trigger-based PPDU power <= max power of
MCS7" on page 1273
Relative Constellation Error in common
This parameter is available when Radio Std is 802.11ax/be.
Specifies RMS EVM limits in a list of 16 elements for HE SU PPDU, HE extended rate
SU PPDU and HE MU PPDU. Each element is an RMS EVM limit of a specific MCS
and DCM state.
