Attributes

Specifies whether to enable 2xLDPC for 802.11bn MU PPDU and 802.11bn TB PPDU signals.

Specifies the carrier frequency for signal generation. This value is expressed in Hz. If you set the NIWLANG_ATTR_MULTI_SEGMENT_GENERATION_MODE attribute to NIWLANG_VAL_SINGLE_GENERATOR, you must set this attribute for each segment using the active channel string 'segmenty'.

Specifies the 320 MHz channelization value if you set the NIWLANG_ATTR_STANDARD attribute to NIWLANG_VAL_STANDARD_80211BE_OFDM or NIWLANG_VAL_STANDARD_80211BN_OFDM. As defined in section 36.3.24.2 of IEEE P802.11be/D7.0 for 320 MHz channel. 320 MHz-1 consists of 320 MHz channels with channel center frequency numbers 31, 95 and 159. 320 MHz-2 consists of 320 MHz channels with channel center frequency numbers 63, 127 and 191.

Specifies the channel width used for transmitting the signal. This value is expressed in Hz.

Specifies the bandwidth across which RU subcarriers are spread, when you set RU Type attribute to dRU.

Specifies the duration of a generated frame excluding idle interval. This attribute is applicable only if you set NIWLANG_PAYLOAD_AUTO_DATA_LENGTH attribute to NIWLANG_VAL_AUTO_PAYLOAD_DATA_LENGTH_MODE_FRAME_DURATION. When the value of NIWLANG_ATTR_FRAME_DURATION results in fractional NIWLANG_ATTR_NUMBER_OF_DATA_SYMBOLS, and if it results in generated frame duration less than 5.484 milliseconds, the number of data symbols is rounded to the next highest integer, otherwise, the number of symbols is rounded to the next lowest integer. The default value is 1 millisecond. Valid values are 100 microseconds to 5.484 milliseconds. Set Function: niWLANG_SetFrameDuration

Specifies whether to enable configuration for sharing of local oscillator (LO) signal in star plus daisy-chained way for multiple PXIe-5842. This attribute is queried as part of the niWLANG_RFSGConfigureFrequencySingleLO function.

Specifies the interframe spacing for signal generation. This value is expressed in seconds. If you set the NIWLANG_ATTR_IDLE_INTERVAL_MODE attribute to NIWLANG_VAL_IDLE_INTERVAL_MODE_SPLIT, the WLAN Generation places half of the interframe spacing on either side of the burst. If you set the NIWLANG_ATTR_IDLE_INTERVAL_MODE attribute to NIWLANG_VAL_IDLE_INTERVAL_MODE_POST_BURST, the WLAN Generation places the interframe spacing at the end of the waveform. The waveform contains zeros for the duration of the interframe spacing.

Specifies how the idle interval is placed in the generated waveform. You cannot set this attribute to NIWLANG_VAL_IDLE_INTERVAL_MODE_SPLIT if you set the NIWLANG_ATTR_RF_BLANKING_ENABLED attribute to NIWLANG_VAL_TRUE.

Specifies the array of splitter loss values in dB for corresponding array of splitter loss frequencies in Hz if Hybrid LO Sharing Mode is set to Mode0.

Specifies the array of splitter loss frequencies in Hz for corresponding array of splitter loss values in dB if Hybrid LO Sharing Mode is set to Mode0.

Specifies whether multi-chassis TClk Synchronization is performed using Timing Module or automatically for multiple PXIe-5842.

Specifies the number of frames to generate. Each iteration of the niWLANG_CreateWaveformComplexF64 or niWLANG_CreateMIMOWaveformsComplexF64 function generates only one frame along with the idle interval that you specify using the NIWLANG_ATTR_IDLE_INTERVAL attribute.

Specifies the ratio at which the WLAN Generation multiplies the Nyquist sample rate to obtain the final sample rate of the signal.

Specifies the number of times the WLAN Generation increases the Nyquist sample rate to obtain the final sample rate of the signal.

Specifies the location of the resource unit (RU) or multiple resource unit (MRU). If an RU is configured, the RU Offset is in terms of the index of 26-tone RU, assuming the entire bandwidth is composed of 26-tone RUs in the 802.11ax, 802.11be and 802.11bn signal. Refer to the Configuring RU Offset/MRU Index topic in RFmx WLAN Generation Help for more information.

Specifies whether contiguous subcarriers form the resource unit (rRU) or non-contiguous subcarriers form the resource unit (dRU). This attribute is applicable only for 802.11bn TB PPDU.

Specifies the IEEE 802.11 standard, which indicates the type of physical layer, for signal generation.

Specifies whether to enable unequal modulation (UEQM) for 802.11bn MU PPDU signals with 2 to 4 spatial streams. UEQM is only supported in non-MU-MIMO beamformed transmission. Modulation order of different spatial streams is determined by value of Pattern Index attribute. This attribute is applicable only when Standard attribute is set to 80211BN MIMOOFDM.

Specifies the unequal modulation pattern index when Unequal Modulation Enabled attribute is set to True. This attribute is applicable only when Standard attribute is set to 80211BN MIMOOFDM. The allowed modulation orders for unequal modulation are QPSK, 16-QAM, 64-QAM, 256-QAM, 1024-QAM and 4096-QAM. Modulation order of the first spatial stream is determined by the MCS Index property value. Pattern Index value determines the modulation order of remaining spatial streams with respect to the first spatial stream, as defined in the Table 38-29 of IEEE P802.11bn/D1.0.

Specifies whether to enable Unframed Data Modulation.
