Character data
Character data follows the syntactic rules of keywords. You can enter text using a short
or a long form. For more information, see
Chapter 9.1.2, "Long and short form"
Querying text parameters
When you query text parameters, the system returns its short form.
Example:
Setting:
SENSe:BANDwidth:RESolution:TYPE NORMal
Query:
SENSe:BANDwidth:RESolution:TYPE?
would return
NORM
9.1.6.4
Character strings
Strings are alphanumeric characters. They have to be in straight quotation marks. You
can use a single quotation mark ( ' ) or a double quotation mark ( " ).
Example:
INSTRument:DELete 'Spectrum'
9.1.6.5
Block data
Block data is a format which is suitable for the transmission of large amounts of data.
The ASCII character # introduces the data block. The next number indicates how many
of the following digits describe the length of the data block. The data bytes follow. Dur-
ing the transmission of these data bytes, all end or other control signs are ignored until
all bytes are transmitted. #0 specifies a data block of indefinite length. The use of the
indefinite format requires an
NL^END
message to terminate the data block. This format
is useful when the length of the transmission is not known or if speed or other consid-
erations prevent segmentation of the data into blocks of definite length.
