Description: Specifies the carrier-to-noise ratio (CNR)of the waveform generated. This value is expressed in dB. Noise bandwidth is equal to the value of the NIWLANG_IQ_RATE attribute. The toolkit ignores the NIWLANG_CARRIER_TO_NOISE_RATIO attribute if you set the NIWLANG_AWGN_ENABLED attribute to NIWLANG_VAL_FALSE.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AG_OFDM, NIWLANG_VAL_STANDARD_80211J_OFDM, NIWLANG_VAL_STANDARD_80211P_OFDM, NIWLANG_VAL_STANDARD_80211G_DSSS_OFDM, NIWLANG_VAL_STANDARD_80211BG_DSSS, or NIWLANG_VAL_STANDARD_80211G_DSSS_OFDM, the active channel string syntax is an empty string.
If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211N_MIMO_OFDM or NIWLANG_VAL_STANDARD_80211AH_MIMO_OFDM, the active channel string syntax is 'channelx'.
If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AC_MIMO_OFDM or NIWLANG_VAL_STANDARD_80211AF_MIMOOFDM, the active channel string syntax is 'segmentx/channely'.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AX_MIMO_OFDM, the active channel string format is 'segmentx/channely' if you set the NIWLANG_PPDU_TYPE attribute to NIWLANG_VAL_PPDU_TYPE_SU_PPDU, NIWLANG_VAL_PPDU_TYPE_EXTENDED_RANGE_SU_PPDU, or NIWLANG_VAL_PPDU_TYPE_MU_PPDU.
If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AX_MIMO_OFDM, the active channel string format is '[userx/]segmenty/channelz' if you set the NIWLANG_PPDU_TYPE attribute to NIWLANG_VAL_PPDU_TYPE_TRIGGER_BASED_PPDU (userx is optional if you want to apply to all the users).

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

The default value is 50. Valid values are -100 to 100, inclusive.
