Character Strings
Strings are alphanumeric characters. They have to be in straight quotation marks. You

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. In the example the 4 follow-
ing digits indicate the length to be 5168 bytes. The data bytes follow. During the trans-
mission 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 for-
mat 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 considerations
prevent segmentation of the data into blocks of definite length.

Activating I/Q Analyzer Measurements
I/Q Analyzer measurements require a special channel setup on the R&S
ZNL. It can be
or
commands. In this case, some - but not all - parameters from the
previously selected application are passed on to the I/Q Analyzer channel setup. In
order to retain
all
relevant parameters from the current application for the I/Q measure-
command to change the application of the current
