Position to start fetching within one record.
Default Value: NISCOPE_VAL_PRETRIGGER
NISCOPE_VAL_PRETRIGGER (477)—Fetches relative to the first pretrigger point requested with niScope_ConfigureHorizontalTiming.
NISCOPE_VAL_NOW (481—Fetch data at the last sample acquired.
NISCOPE_VAL_START (482)—Fetch data starting at the first point sampled by the digitizer.
NISCOPE_VAL_TRIGGER (483)—Fetch at the first posttrigger sample.
NISCOPE_VAL_READ_POINTER (388)—The read pointer is set to zero when a new acquisition is initiated. After every fetch the read pointer is incremented to be the sample after the last sample retrieved. Therefore, you can repeatedly fetch relative to the read pointer for a continuous acquisition program.
