niRFSG Write Arb Waveform
Writes an arbitrary waveform to the NI-RFSG device. This VI enters the I and Q vectors of a complex baseband signal. If the waveform to be written is already allocated using the niRFSG Allocate Arb Waveform VI, the more data pending? parameter is ignored. This VI has six polymorphic instances that take as data input a complex cluster, a waveform datatype (CWDT), Direct DMA, Complex DBL, I16, and I-Q arrays. The NI 5670/5671 device must be in the Configuration state before you call this VI.
Supported Devices: NI 5670/5671/5672
