Inputs/Outputs

  • cgenclassrn.png niwlan generation session —

    niwlan generation session specifies the niWLAN generation session refnum.

  • cpath.png file path —

    file path specifies the absolute path to the TDMS file to which the WLAN Generation writes the waveforms.

  • cenum.png operation —

    operation specifies the operation to perform on the file. The default value is create or replace.

    open (0)

    Opens an existing file to write the niWLANG settings.
    open or create (1)

    Opens an existing file or creates a new file if the file does not exist.

    create or replace (2)

    Creates a new file or replaces an existing file.

    create (3)

    Creates a new file.
  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • igenclassrn.png niwlan generation session out —

    niwlan generation session out passes a reference of the WLAN generation session to the next VI.

    Note Close the niWLAN generation session reference using the niWLANG Close Session VI before the completion of execution to avoid possible memory leak issues.
  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.

    In addition to creating the waveform, this VI also saves the Headroom and IQ Rate properties for each waveform. The VI reads the RF Blanking Marker Positions property and saves the value to the file. The RF Blanking Marker Positions property stored in the file is applicable to all waveforms stored in the file. This VI also saves Signal Bandwidth property for each waveform, which is computed as follows:

    Signal Bandwidth = 2 * {(Channel Bandwidth/2) + |Max Carrier Frequency Offset|}
