Property of niScope

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

Start (482)

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

Trigger (483)

Fetch at the first posttrigger sample.

Pretrigger (477)

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

Now (481)

Fetch data at the last sample acquired.
