Data Type: int32
Access:read/write
Functions:niWLANA_SetScalarAttributeI32
niWLANA_GetScalarAttributeI32
Description: Specifies whether to enable equalization. The IEEE Standard 802.11-2007 does not allow equalization before computing EVM.

Note: If you enable equalization, the toolkit does not support measurement of I/Q impairments and decoding of bits.

Note: Equalization is not supported for signals with data rates of 22 Mbps and 33 Mbps. Do not set this attribute to NIWLANA_VAL_TRUE when performing demodulation measurements on signals with data rates of 22 Mbps and 33 Mbps.

The default value is NIWLANA_VAL_FALSE.

Get Function: niWLANA_GetDSSSDemodEqualizationEnabled
Set Function: niWLANA_SetDSSSDemodEqualizationEnabled
Values:
NIWLANA_VAL_FALSE (0)Disables equalization.
NIWLANA_VAL_TRUE (1)Equalizes the payload with an 11-tap channel filter, which includes five precursor taps and five post-cursor taps, before EVM computation.
