Description
This programs the circulation type for the video stroke generator. There are two options, both operate from an
external trigger (or enable) signal: Single will move the pattern from start to stop offset and will leave the video

repeat the cycle as long as triggers are applied to the instrument. The circulation range is defined by the
ri3156B_set_video_offset_range () function
