Details
You can use this command to read all the data that are stored in the buffer.
You can send this command even if the instrument is saving data in the buffer.
When this command is sent, it will return the data stored up to that point. Subsequent execution of the
command will not display the data already returned. However, once the buffer has been fully filled,
you can query all the stored data again by sending this command.
For example, if
BATTery:TRACe:DATA? "VOLT, CURR"
is sent, the subsequent
BATTery:TRACe:DATA? "MODE"
command will not return the current and voltage information. You
can get additional buffer data by sending the command
BATTery:TRACe:DATA:SELected?
.
When specifying buffer elements, you can:
Specify buffer elements in any order.
Include up to 12 elements in a single list.
Repeat elements as long as the number of elements in the list is less than 12.
Use a comma to separate multiple elements for a data point.
Use quotation mark to enclose all the elements.
