Description: Returns the power in the upper offset channels relative to the power in the reference channel measured over the bandwidth specified by the NIWLANA_CHANNEL_BANDWIDTH attribute. This value is expressed in dBc. The number of offset channels is specified by the NIWLANA_ACP_NUMBER_OF_OFFSETS attribute. The elements in the array are in the order of increasing frequency separation with respect to the reference channel.

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.

Refer to the Configuring Active Channels (LabWindows/CVI) topic for more information about configuring active channels.
