Writes an arbitrary waveform to the NI-RFSG device. This VI configures the I and Q vectors of a complex baseband signal. If the waveform to write is already allocated using the niRFSG Allocate Arb Waveform VI, the more data pending? parameter is ignored. This VI has nine polymorphic instances that accept as data input a complex cluster, a waveform datatype (CWDT), Complex DBL, Complex SGL, I16, and I/Q arrays. The PXI-5670/5671 must be in the Configuration state before you call this VI. When streaming is enabled, you can call this VI when the PXIe-5672/5673/5673E, PXIe-5820/5840 is in the Generation state.

Note  On the PXIe-5644/5645/5646, PXIe-5672/5673/5673E, and PXIe-5820/5840, the more data pending? parameter is always ignored. To write data in blocks on these devices, you must allocate the waveform before writing it.

Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840
