Range: 1 to 16
Default: Equal to the number of connected instruments. For example, it’s 3 when the System Configuration is ‘IEEE 802.11ax Mx3’.
Set the number of transmit chains when Channel State is ON or when System Configuration is IEEE MxN (1 SG). When Channel State is Off and System Configuration is not IEEE MxN (1 SG), the number of transmit chains is automatically set equal to the number of connected instruments and can't be edited.
Choices: 6 Mbps | 9 Mbps | 12 Mbps | 18 Mbps | 24 Mbps | 36 Mbps | 48 Mbps | 54 Mbps
Default: 36 Mbps
Coupling: Affects the Number of Data Symbols in One Frame and Total Sample Points.
Select the data rate for the legacy WLAN.
Indicates the modulation type.
Indicates the coding rate of the BBC encoder.
Choices: On | Off
Default: On
Enable or disable the scrambler. The scrambler scrambles the data to reduce the probability of long sequences of zeros and ones.
Range: 0 - 127
Default: 93
Set the initial state of the scrambler in decimal format. The decimal number is converted to 7 bits for input into the scrambler.
Choices: On | Off
Default:On
Enable or disable the BCC encoder.
Choices: On | Off
Default: On
Enable or disable the interleaver. BCC Interleaver interleaves the bits of each spatial stream (changes order of bits) to prevent long sequences of adjacent noisy bits from entering the BCC decoder. Interleaving is applied only when BCC encoding is used.
Displays the number of octets in the current MPDU, which is comprised of MSDU, MAC Header, and MAC FCS.
Choices: All 0s | PN9 | PN15 | User file
Default: PN9
Select the payload data source.
The user file must be in binary form. The least significant bit (LSB) of the first byte in the user data file will be the first bit of the user payload; the LSB of the second byte in the user file will be the ninth bit of the user payload, and so on. If User file is selected as the Data Type, the value displayed in the Data Length field will be equal to the length of the user's data file, up to the maximum data length.
Range: 0 to 511
Default: 511
Coupling: Only visible when Data Type is PN9.
Specify a seed in decimal format to generate a PN9 data sequence. The LSB of the seed comes out first. For example, if you enter a seed value of 10 (1010 in binary), the first 9 bits of the PN9 sequence are 0 1 0 1 0 0 0 0 0, with an increasing index from left to right. For more information, see PN Sequence Generation.
Range: 0 to 32767
Default: 32767
Coupling: Only visible when Data Type is PN15.
Specify a seed in decimal format to generate a PN15 data sequence. The LSB of the seed comes out first. For example, if you enter a seed value of 10 (1010 in binary), the first 15 bits of the PN15 sequence are 0 1 0 1 0 0 0 0 0 0 0 0 0 0 0, with an increasing index from left to right. For more information, see PN Sequence Generation.
Set the number of data bytes in a frame. The value is limited by MPDU Length.
Click the 
button in this cell to select a user file
as the data source.
This cell displays the number of data bytes in the user file when it is selected as the payload data source.
Click the button in this cell to open the MAC Header Dialog (see the dialogs below), which enables or disables pre-pending the MAC
header to the data payload. You can select General, RTS, or CTS MAC frame
format by clicking the down arrow in the top right corner of the MacHeaderDialog.
You can set the desired data in each of the individual fields for each
format. You can also disable these fields if the data is no longer desired
by clearing the Mac Header (hex) checkbox.
Use this cell to enable or disable appending the MAC FCS to the data payload. The FCS is automatically calculated by the software if this cell is enabled. Note: When the MAC header is not selected, then the FCS is applied to just the payload.
Use this cell to enable or disable incrementing
the Sequence Number within the 
Sequence
Control field
in the MAC Header. When it is turned ON, the Sequence Number increments
by one after each user-specified interval of new frames. For an example
of how incrementation works, see Incrementing Sequence and Fragment Numbers.
The number of frames you set in this cell determines when the Sequence Number within the Sequence Control field in the MAC Header is incremented. For an example of how incrementation works, see Incrementing Sequence and Fragment Numbers.
Use this cell to enable or disable incrementing the Fragment Number
within the Sequence Control field
in the MAC Header. When it is turned ON, the Fragment Number increments
by one after every assignment of a new frame. This field uses the Increment
Sequence Number by: (Frame) value as the upper limit. When the upper limit
is reached, incrementation wraps back to zero. For an example of how incrementation
works, see Incrementing Sequence and Fragment Numbers.
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.
