Remote Control – Basics
Structure and Syntax of the Device Messages
Strings
Strings must always be entered in quotation marks (' or ").
Example:
SYSTem:LANGuage "SCPI"
or
SYSTem:LANGuage 'SCPI'
Block data
Block data is a transmission format which is suitable for the transmission of large
amounts of data. A command using a block data parameter has the following struc-
ture.
Example:
HEADer:HEADer #45168xxxxxxxx
ASCII character # introduces the data block. The next number indicates how many
of the following digits describe the length of the data block. In the example, the 4 fol-
lowing digits indicate the length to be 5168 bytes. The data bytes follow. During the
transmission of these data bytes, all End or other control signs are ignored until all
bytes are transmitted.
This format only supports a byte count up to 9 digits for the number of bytes. For
more than 999999999 bytes, following additional format is used.
Example:
HEADer:HEADer #(1100000000) xxxxxxxx
The byte length count if put into brackets. In the example, the byte counts indicates
a length of 1.100.000.000 bytes. The data bytes follow the close bracket.

Overview of Syntax Elements
The following survey offers an overview of the syntax elements.
a
:
The colon separates the key words of a command.
In a command line the colon after the separating semicolon marks the
uppermost command level.
;
The semicolon separates two commands of a command line. It does not
alter the path.
,
The comma separates several parameters of a command.
?
The question mark forms a query.
*
The asterisk marks a common command.
"
Quotation marks introduce a string and terminate it.
#
The double dagger introduces block data.
A white space (ASCII code 0 to 9, 11 to 32 decimal, e.g. blank) separates
header and parameter.
