Configures the start position to use for writing a waveform before calling the niRFSG Write Arb Waveform VI. This VI allows you to write to arbitrary locations within the waveform. These settings apply only to the next write to the waveform specified by the name input of the niRFSG Allocate Arb Waveform VI or niRFSG Write Arb Waveform VI. Subsequent writes to that waveform begin where the last write ended, unless this VI is called again.

Note  If you use this VI to write the waveform that is currently generating, an undefined output may result.

Supported Devices: PXIe-5644/5645/5646, PXIe-5820/5840

relative to specifies the reference position in the waveform. The position and offset together determine where to start loading data into the waveform.

Start of Waveform The reference position is relative to the start of the waveform.
Current Position The reference position is relative to the current position.
