Description: Returns the lowest margin for each linear segment of the spectral emission mask, as defined in section 17.3.9.2 of IEEE Standard 802.11a-1999, section 18.4.7.3 of IEEE Standard 802.11b-1999, and section 20.3.21.1 of IEEE Standard 802.11n-2009. The resulting lowest margin indicates the minimum difference between the acquired PSD spectrum and the spectral mask.

If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AG_OFDM, NIWLANA_VAL_STANDARD_80211J_OFDM, NIWLANA_VAL_STANDARD_80211P_OFDM, NIWLANA_VAL_STANDARD_80211BG_DSSS, or NIWLANA_VAL_STANDARD_80211G_DSSS_OFDM, you must use an empty string to query this attribute.
If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211N_MIMO_OFDM or NIWLANA_VAL_STANDARD_80211AH_MIMO_OFDM, you must use 'channelx' as the active channel string format to query this attribute.
If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AC_MIMO_OFDM, you must use '[segmentx/]channely' as the active channel string format to query this attribute. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1.
If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AC_MIMO_OFDM or NIWLANA_VAL_STANDARD_80211AX_MIMO_OFDM, you must use 'channelx' as the active channel string format when you set the NIWLANA_SPECTRAL_MASK_COMBINED_MASK_ENABLED to NIWLANA_VAL_TRUE.
If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AF_MIMO_OFDM, you must use '[segmentx/]channely' as the active channel string format to query this attribute. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1.
