| Description: | Returns the standard deviation of cross power measurements. This value is expressed in dB. The cross power for 'channelx' is the contribution of the power from streams other than 'streamx' in 'channelx'. To get the individual contributions of each stream, use the format 'channelx/streamy' for the active channel, where x is not equal to y. 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 'channelx' and 'channelx/streamy' as the active channel string formats 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 and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use '[segmentx/]channely' and '[segmentx/]channely/streamz' as the active channel string formats 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_80211AH_MIMO_OFDM, and the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_FALSE, you must use 'channelx' and 'channelx/streamy' as the active channel string formats to query this attribute. Note: The result of the NIWLANA_RESULT_OFDM_DEMOD_CHANNEL_MATRIX_CROSS_POWER_AVERAGE attribute is invalid if you set the NIWLANA_OFDM_DEMOD_COMBINED_SIGNAL_DEMODULATION_ENABLED attribute to NIWLANA_VAL_TRUE. Refer to the Configuring Active Channels (LabWindows/CVI) topic for more information about configuring active channels. |
