# Configure Power Level Type (G Dataflow)

Version:

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.

## session in

Instrument session obtained from .

## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

## power level type

Type of power NI-RFSG uses based on the value of the Power Level property.

Name Value Description
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.

Default: Average Power

## session out

Reference to your instrument session passed to the next node.

## error out

Error information.

The node produces this output according to standard error behavior.
