Type Affected by Where saved Default value

Query only

Recall settings

Instrument reset

Power cycle

Not applicable

Usage

:TRACe:DATA? <startIndex>, <endIndex>

:TRACe:DATA? <startIndex>, <endIndex>, "<bufferName>"

:TRACe:DATA? <startIndex>, <endIndex>, "<bufferName>", <bufferElements>

:TRACe:DATA? <startIndex>, <endIndex>, "<bufferName>", <bufferElements>,

Beginning index of the buffer to return; must be 1 or greater

Ending index of the buffer to return

A string that indicates the reading buffer; the default buffers (defbuffer1 or

defbuffer2) or the name of a user-defined buffer; if no buffer is specified,

defbuffer1

is used

A list of elements in the buffer to print; if nothing is specified, READing is used; see

Details for the list of options for buffer elements; a maximum of 14 comma-delimited

buffer elements may be specified

Details

The output of :TRACe:DATA? is affected by the data format selected by :FORMat[:DATA]. If you

set FORMat[:DATA] to REAL or SREAL, you will have fewer options for buffer elements. The only

buffer elements available are READing, RELative, and EXTRa. If you request a buffer element that

is not permitted for the selected data format, the instrument generates the error 1133, "Parameter 4,

Syntax error, expected valid name parameters."

To change the number of digits returned in a remote command reading, use the

:FORMat:ASCii:PRECision command.

When specifying buffer elements, you can:

• Specify buffer elements in any order.

• Include up to 12 elements in a single list. You can repeat elements as long as the number of

elements in the list is less than 12.

• Use a comma to delineate multiple elements for a data point.
