Configures the start position to use for writing a waveform before calling the niRFSG Write Arb Waveform VI. This VI allows you to write to arbitrary locations within the waveform. These settings apply only to the next write to the waveform specified by the name input of the niRFSG Allocate Arb Waveform VI or niRFSG Write Arb Waveform VI. Subsequent writes to that waveform begin where the last write ended, unless this VI is called again.

Note If you use this VI to write the waveform that is currently generating, an undefined output may result.

Supported Devices: PXIe-5644/5645/5646, PXIe-5820/5830/5831/5832/5840/5841/5842/5860

Inputs/Outputs

  • cstr.png name —

    name specifies the name of the waveform. This string is case-insensitive and alphanumeric, and it cannot use reserved words.

  • civrn.png instrument handle —

    instrument handle identifies your instrument session. instrument handle is obtained from either the niRFSG Initialize VI or the niRFSG Initialize With Options VI.

  • ci32.png relative to —

    relative to specifies the reference position in the waveform. The position and offset together determine where to start loading data into the waveform.

    Start of Waveform The reference position is relative to the start of the waveform.
    Current Position The reference position is relative to the current position.
  • ci32.png offset —

    offset specifies the offset from the relative to parameter at which to start loading the data into the waveform.

  • cerrcodeclst.png error in —

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

  • iivrn.png instrument handle out —

    instrument handle out passes a reference to your instrument session to the next VI. instrument handle out is obtained from the niRFSG Initialize VI or the niRFSG Initialize With Options VI.

  • ierrcodeclst.png error out —

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