Specific Commands

TRACe:DATA?

Description This query indicates the data segment to be returned. Each

segment contains between 1 and 128 data. If the segment

requested by the user is not valid, no data is included in the

segment and the “Segment not allowed” error message will be

raised.

Syntax

TRAC:DATA? #

Parameters The “#” parameter is the data segment to be returned in the

“999” format.

Example

For an acquisition containing 257 data, the user can expect to

receive three segments (two segments with 128 data each and

one segment with 1 data). To retrieve the data, the user must

send the following commands:
TRAC:DATA? 0
TRAC:DATA? 1
TRAC:DATA? 2
Sending TRAC:DATA? 3 then will raise the “Segment not

allowed” error message.
