Short Name: FetchRelativeTo
Specifies the absolute location within the acquired record from which to begin fetching.
| Most recent sample (700) | Specifies that fetching occur relative to the most recently acquired data. The Fetch Offset property must be negative. |
| First sample (701) | Specifies that fetching occurs at the first sample acquired by the device. If the device wraps its buffer, then the first sample is no longer available. In this case, NI-RFSA returns an error if the fetch offset is in the overwritten data. |
