| Description: | Returns the maximum total power over any 1 MHz portion of the spectrum. This value is expressed in W/MHZ. You can use this attribute to verify that the device under test (DUT) conforms to section 17.3.9.1 of IEEE Standard 802.11a-1999, section 18.4.7.1 of IEEE Standard 802.11b-1999, or section 20.3.21.3 of IEEE Standard 802.11n-2009, which specifies the maximum output power in certain cases. 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, NIWLANA_VAL_STANDARD_80211AF_MIMO_OFDM or NIWLANA_VAL_STANDARD_80211AX_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. Get Function: niWLANA_GetMaxSpectralDensity |
