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.
