Strings
Strings must always be entered in quotation marks (' or ").
Example:
SYSTem:COMMunicate:SOCKet:IPADdress "192.168.1.128"
SYSTem:COMMunicate:SOCKet:IPADdress '192.168.1.128'
Block data
Block data are a transmission format which is suitable for the transmission of large
amounts of data. A command using a block data parameter has the following structure:
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 four 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.

Responses to queries
You can query each setting command by adding a question mark. According to SCPI,
the responses to queries are partly subject to stricter rules than in the standard IEEE
488.2.
●
The requested parameter is transmitted without a header.
User Manual 5601.1343.02 ─ 09
A colon separates the mnemonics of a command.
The semicolon separates two commands within a program message. It does not alter the path.
A comma separates several parameters of a command.
A question mark forms a query.
An asterisk marks a common command.
Quotation marks introduce a string and terminate it.
A whitespace (ASCII-Code 0 to 9, 11 to 32 decimal, e.g. blank) separates the header from the
parameters.
