I-Q Arrays SGL

Writes an arbitrary waveform to the NI-RFSG device.

This node accepts the I and Q vectors of a complex baseband signal containing singles.

When streaming is enabled, you can call this node when the NI-RFSG device is in the Generation state.

Inputs/Outputs

datatype_icon

session in

Instrument session obtained from Initialize With Options.

datatype_icon

error in

Error conditions that occur before this node runs.

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

Standard Error Behavior

Default value: No error

datatype_icon

I data

In-phase (I) component of the complex baseband signal.

datatype_icon

Q data

Quadrature-phase (Q) component of the complex baseband signal.

datatype_icon

name

Name used to store the waveform.

This string is case-insensitive and alphanumeric, and it cannot use reserved words.
datatype_icon

more data pending?

Boolean value that indicates whether the data block contains the end of the waveform.

True Allows the data to be appended to the waveform later.
False This data block contains the end of the waveform.

Splitting the waveform into multiple data blocks can reduce the memory requirements of the write operation. You can append data to a previously written waveform by using the saved waveform name.

Note This input is always ignored when using the PXIe-5644/5645/5646/5673E/5820/5840. To write data in blocks on these models, you must allocate the waveform before writing it.
datatype_icon

session out

Reference to your instrument session passed to the next node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
