13.18.4.4 Waveform, Data and List Format
The R&S SMW uses a simple tag-oriented format for externally or internally generated
waveforms, data and control lists. Files with this format can be transmitted via the
GPIB interface from an external computer to the instrument and vice versa. These files
are transmitted as a binary data block, using SCPI command [:SOURce<hw>]:BB:
ARBitrary:WAVeform:DATA, [:SOURce<hw>]:BB:DM:DLISt:DATA, and [:
SOURce<hw>]:BB:DM:CLISt:DATA.
Tag general format
Tags are self-contained information units, enclosed in braces { }. Their general format
is {Name: Data} or {Name-Length: Data}. The colon separates the name part
and the data part. The colon can be followed by a space for the sake of legibility.
●
The Name identifies the tag. It is always expressed in capital letters.
●
The Data is tag-specific, and usually it is in ASCII plain text.
