(4) All of the scan data in the Acquisition Buffer
has been read. The buffer is now empty.
Part 4 – The oldest complete Trigger Block currently in the Acquisition Buffer has been read. The program
example demonstrates how the
R3
command will read all of the scan data currently residing in the buffer.

• Line 1: Request the current status of the Acquisition Buffer.
•
Line 2: Retrieve the status.
•
Line 3: The screen will show the current status of the Acquisition Buffer.
Before all of the scan data is read, the Buffer Status String response indicates that the total number of Trigger
Blocks available in the buffer is 5, and the total number of scans available in the buffer is 18860 (20215-1355).
Furthermore, it shows that the current location of the Read Pointer is at Pre-Trigger scan -100 in the first Trigger
Block . All of the scan data can be retrieved as follows:
•
Line 4: Get all of the scan data in the Acquisition Buffer.
• Line 5: Get the response.
• Line 6: The screen will show all 18860 scans of data for each of the four (4) configured channels.
•
Line 7: Now, get the current status of the Acquisition Buffer.
•
Line 8: Get the response.
•
Line 9: The screen will show the new current status of the Acquisition Buffer.
Notice that after all of the scan data is read, the Acquisition Buffer is now complete empty.
