Specifies the way the driver interprets the value of the Power Level (dBm) property. In average power mode, NI-RFSG automatically scales waveform data to use the maximum dynamic range. In peak power mode, waveforms are scaled according to the Software Scaling Factor property.

Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, 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 either the niRFSG Initialize VI or the niRFSG Initialize With Options VI.

  • ci32.png power level type —

    power level type specifies the way the driver interprets the value of the Power Level (dBm) property. NI-RFSG sets the Power Level Type property to this value.

    Average Power (default) Indicates the desired power averaged in time. The driver maximizes the dynamic range by scaling the I/Q waveform so that its peak magnitude is equal to one. If your write more than one waveform, NI-RFSG scales each waveform without preserving the power level ratio between the waveforms. This value is not valid for the PXIe-5820.
    Peak Power Indicates the maximum power level of the RF signal averaged over one period of the RF carrier frequency (the peak envelope power). This setting requires the magnitude of the I/Q waveform be less than or equal to one. When using peak power, the power level of the RF signal matches the specified power level at moments when the magnitude of the I/Q waveform equals one. If you write more than one waveform, the relative scaling between waveforms is preserved. In peak power mode, waveforms are scaled according to the Software Scaling Factor property.
  • 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.
