Fetch:Fetch Relative To

Short Name: Fetch Relative To

Specifies which point in the acquired waveform is the first to be fetched. This property specifies what the 'Fetch Offset' is relative to.

Defined Values

Start—Fetch data starting at the first point sampled by the digitizer.

Trigger—Fetch at the first posttrigger sample.

Pretrigger—Fetches relative to the first pretrigger point requested with niScope Configure Horizontal Timing.

Now—Fetch data at the last sample acquired.

Read Pointer—The read pointer is set to zero when a new acquisition is initiated. After every fetch the read pointer is incremeted to be the sample after the last sample retrieved. Therefore, you can repeatedly fetch relative to the read pointer for a continuous acquisition program.

Default Value: Pretrigger
