However, once the buffer has been fully filled, you can retrieve all the stored readings again by
sending this command. For example, if DATA:DATA? "READ, SOURce" is sent, the subsequent
DATA:DATA? "MODE" command will not return mode information. You can get additional buffer data
by sending the command DATA:DATA:SELected?.
When specifying buffer elements, you can:

Specify buffer elements in any order.

Include up to 10 elements in a single list.

Repeat elements as long as the number of elements in the list is less than 10.

Use a comma to delineate multiple elements for a data point.

Use single or double quotes to enclose all the elements.
The options for <bufferElements> are described in the following table.

The RELative and RSTamp elements are defined as the time since the first reading was stored in

represent absolute time from the internal real-time clock (RTC).
