| Description: | Returns the maximum across iterations of absolute power measurements in the frequency domain. This value is expressed in dBm. Absolute power is the frequency domain power measured from estimated channel matrix. You can query total power of each stream and each channel, power of each stream in each channel, and total power of channel matrix. 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_FALSE, you must use the following active channel string formats to query this attribute: 'channelx' for total power of channelx. 'streamx' for total power of streamx. 'channelx/streamy' for power of streamy in channelx. An empty string for total power. 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 the following active channel string formats to query this attribute: An empty string for total power. 'streamx' for total power of streamx. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AC_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use the following active channel string formats to query this attribute: '[segmentx/]channely' for total power of 'channely' in 'segmentx'. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]streamy' for total power of 'streamy' in 'segmentx'. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]channely/streamz' for power of streamz in channely in segmentx. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx]' for total power. Use an empty string 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, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_TRUE, you must use the following active channel string formats to query this attribute: 'segmentx' for total power. Use an empty string if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]streamy' for total power of streamy in segmentx. '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_80211AH_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use the following active channel string formats to query this attribute: 'channelx' for total power of channelx. 'streamx' for total power of streamx. 'channelx/streamy' for power of streamy in channelx. An empty string for total power. 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 the following active channel string formats to query this attribute: '[segmentx/]channely' for total power of channely in segmentx. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]streamy' for total power of streamy in segmentx. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]channely/streamy' for power of streamz in channely in segmentx. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx]' for total power. An empty string if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AX_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use the following active channel string formats to query this attribute: '[segmentx/]channely' for total power of channely in segmentx. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]streamy' for total power of streamy in segmentx. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]channely/streamz' for power of streamz in channely in segmentx. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]' for total power. Empty string, if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. 'userw/[segmentx/]channely' for total power of channely in segmentx of userw in MU PPDU signals. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. 'userw/[segmentx/]streamy' for total power of streamy in segmentx of userw in MU PPDU signals. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. 'userw/[segmentx/]channely/streamz' for power of streamz in channely in segmentx of userw in MU PPDU signals. 'segment0/' is optional if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. 'userw/[segmentx/]' for total power of userw in segmentx of MU PPDU signals. '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_80211AX_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_TRUE, you must use the following active channel string formats to query this attribute: 'segmentx' for total power. Use an empty string if the NIWLANA_NUMBER_OF_SEGMENTS attribute is set to 1. '[segmentx/]streamy' for total power of streamy in segmentx.
