| Description: | Returns the minimum across iterations of spectral flatness margin. This value is expressed in dB. Spectral flatness margin is the minimum margin of the upper and lower spectral flatness margins. Refer to the OFDM Spectral Flatness Margin help topic for more information about spectral flatness margin. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AG_OFDM, NIWLANA_VAL_STANDARD_80211J_OFDM, NIWLANA_VAL_STANDARD_80211P_OFDM or NIWLANA_VAL_STANDARD_80211BG_DSSS, you must use an empty string as the active channel string format to query this attribute. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211N_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED to NIWLANA_VAL_FALSE, you must use 'channelx/streamy' as the active channel string format to query this attribute. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211N_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_TRUE, you must use 'streamy' as the active channel string format to query this attribute. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AH_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use 'channelx/streamy' as the active channel string format to query this attribute. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AC_MIMO_OFDM or NIWLANA_VAL_STANDARD_80211AX_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use '[segmentx/]channely/streamz' 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, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_TRUE, you must use '[segmentx/]streamy' 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_80211AF_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use '[segmentx/]channely/streamz' as the active channel string format to query this attribute. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1.
