MCS of Trigger-based PPDU
This parameter is available only when Radio Std is 802.11ax/be.
MCS (Modulation Coding Scheme) information is defined in Trigger Frame, with a
range from 0~11. HE Trigger-based PPDU format is used for a PPDU that is a
response of a Trigger frame, which does not include MCS information. You need to
manually set the MCS information to select EVM limit for your test.
See "More Information about HE PPDU" on page 1276.
