This topic applies to the following Generation Modes:
HE SU PPDU
HE Extended Range SU PPDU
HE NDP
Enable/disable space time block coding. STBC encoder spreads constellation points from Nss spatial stream into Nsts space-time streams using a space-time block code. STBC is allowed only with single spatial stream and two space-time streams.
Select the Symbol interval (with guard interval) for the HE-LTF field. The current combinations are 1x HE-LTF + 0.8 µs, 2x HE-LTF + 0.8 µs, 2x HE-LTF + 1.6 µs ,4x HE-LTF + 3.2 µs, and 4x HE-LTF + 0.8 µs.
Specify the number of HE-LTFs.
This is information indicating the total number of space time streams , which is equal to the sum of the Nsts for each user.
Set the number of transmit chains. When the number of instruments is more than 1 and the Channel State is Off, it automatically equals to the number of instruments and can't be changed, otherwise, it's editable.
Get or set Pre-FEC Padding Factor.
Set or Get the Maximum Packet Extension Duration for Current PPDU.
Indicates whether the frame is Uplink or Downlink. The field is set to DL for TDLS.
Set or Get the remaining time duration in the current TXOP. Set to 8449 μs to indicate no duration information. Set to value other than 8449 μs to indicate the duration information for NAV setting and protection of the TXOP. When the value ranges from 0 to 504 μs, the granularity is 8 μs. When the value ranges from 512 to 8448 μs, the granularity is 128 μs.
Get or Set the Base station identifier.The BSS Color field is an identifier of the BSS.
Indicate pre-coder change/no change between L-LTF and HE-LTF.Set to 1 indicates that the pre-HE-STF portion of the SU PPDU is spatially mapped differently from HELTF1.Set to 0 indicates that the pre-HE-STF portion of the SU PPDU is spatially mapped the same way as HELTF1 on each tone.
Indication of CCA Level, Interference Level accepted, TX Power.
Indicate a PPDU with enhanced immunity to Doppler.
Enable or disable the mode of Single spatial stream HE-MCS 0 in the right 106-tone RU of the primary 20 MHz channel for an HE Extended Range SU PPDU.
Indication of midamble periodicity. The midamble is present only when the number of OFDM symbols in the HE Data field is larger than the signaled midamble periodicity plus 1 and the Doppler indication is on.
Set the contents of the spatial mapping matrix.
Displays the index for each user.
Displays the Number of Spatial Streams (Nss,u) used by current user. Its maximum value is 8 for Single User, while it is 4 for Multi User MIMO. The HE extended range SU PPDU can only be transmitted with MCS0, MCS1, MCS2 and only with 1 spatial stream.
Displays the Number of Space Time Streams (Nsts,u) of current user. When STBC is OFF, it is equal Nss,u. When STBC is ON, it equals 2 times Nss,u.
Double-click to go to the User Configuration property grid where you can select the MCS Index. Note that some MCS Indexes are defined as invalid by the standard and are not selectable. The HE extended range SU PPDU can only be transmitted with MCS0, MCS1, MCS2.
Double-click to go to the User Configuration property grid where you can select the Channel Coding Mode. Choices are BCC and LDPC encoding.
Range: -90 to 90 degrees
Set the baseband quadrature angle adjustment for Waveform 1 before channel fading and mirror spectrum.
The number of parameter groups depends on Number of Transmit Chains (Ntx). Each group is identified with an incremented waveform number, such as Waveform 1, Waveform 2, and so on.
Range: -10 to 10 dB
Set the baseband IQ gain balance for Waveform 1 before channel fading and mirror spectrum.
The number of parameter groups depends on Number of Transmit Chains (Ntx). Each group is identified with an incremented waveform number, such as Waveform 1, Waveform 2, and so on.
