Configure Power Level Type
Specifies how NI-RFSG interprets the value of the Power Level property.
In average power mode, NI-RFSG automatically scales waveform data to use the maximum dynamic range. In peak power mode, NI-RFSG scales waveforms according to the Software Scaling Factor property.
Inputs/Outputs
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error
power level type
Type of power NI-RFSG uses based on the value of the Power Level property.
| Average Power | 0 |
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 | 1 |
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 theSoftware Scaling Factor property. |
