5-13 Set (Query) the DataSample Rate to 62.5 mHz (0) through 512 Hz (13) or Trigger (14).
5-13 Set (Query) the Data Scan Mode to 1 Shot (0) or Loop (1).
5-13 Software trigger command. Same as trigger input.
5-13 Set (Query) the Trigger Starts Scan modeto No (0) or Yes (1).
5-13 Start or continue a scan.
5-13 Pause a scan. Does not reset a paused or done scan.
5-14 Reset the scan. All stored data is lost.

5-15
5-15 Query the value of Display i (1,2). Returns ASCII floating point value.
5-15 Query the value of 2 thru 6 paramters at once.
5-16 Query the value of Aux Input i (1,2,3,4). Returns ASCII floating point value.
5-16 Query the number of points stored in Display buffer.
5-16 Read k≥1 points starting at bin j≥0 from Display i (1,2) buffer in ASCII floating point.
5-16 Read k≥1 points starting at bin j≥0 from Display i (1,2) buffer in IEEE binary floating point.
5-17 Read k≥1 points starting at bin j≥0 from Display i (1,2) buffer in non-normalized binary floating
