Returns coefficients you can use to convert unscaled data to scaled I/Q data.

Acquired data may be unscaled when sent by a peer-to-peer stream or when fetched as unscaled data. Use this VI to scale such I/Q values.

The coefficient info array returns one cluster that contains gain and offset elements. To obtain scaled I/Q values, multiply the unscaled data by the gain value of the cluster, then add the offset.

Note The coefficients are calculated by NI-RFSA for the current configuration of the device, so they are valid only for acquisitions obtained with the same device configuration.

Supported Devices: PXIe-5663/5663E/5665/5667/5668, PXIe-5820/5830/5831/5832/5840/5841/5842/5860

Inputs/Outputs

  • civrn.png instrument handle —

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

  • 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 is obtained from the niRFSA Initialize VI or the niRFSA Initialize With Options VI and identifies a particular instrument session.

  • i1dnclst.png coefficient info —

    coefficient info returns the array with coefficient information.

  • idbl.png Offset —

    offset returns the number to add to the data from a peer-to-peer stream after the gain has been applied in order to scale unscaled data.

  • idbl.png Gain —

    gain returns the multiplier to use to scale data obtained from a peer-to-peer stream.

  • idbl.png Reserved1 —

  • idbl.png Reserved2 —

  • ierrcodeclst.png error out —

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