SCPI Commands

:DATA|:TRACe[:DATA]

:DATA|:TRACe[:DATA]
This command assigns the specified values to the specified user variable.
The user variable must first be defined by the :DATA|:TRACe:DEFine or
:PAGE:CHANnels:UVARiable:DEFine command, or on the CHANNELS: USER
VARIABLE DEFINITION page.
To transfer a block of data (REAL), you must set up the format by using FORMat
Subsystem commands. Block transfer is fast because the block is directly loaded
into the specified user variable.
To transfer ASCII data, the default is ASCII, so you do not need to set up the format
unless you changed it to REAL. ASCII transfer is slower than block transfer because
the data is transferred in ASCII, then converted and loaded into the specified user
variable.
If the data source is a single numeric_value, each element of the specified user
variable is set to the numeric_value.
Also, you can specify a different numeric_value for each element of the user
variable.
If the number of numeric_values are less than the defined size of user variable, the
remaining data elements are filled with last sent data.
If too many numeric_values are sent, the 4155C/4156C generates error -223 (too
much data), and the extra data are ignored.
The query of this command returns the data values for the specified data variable,
according to the format determined by commands in the FORMat subsystem. For
the possible data variables that you can specify, see the previous command
(:DATA:CATalog?).
Syntax

{ ,numeric_value} )
Query syntax is as follows:
