R&S SMB Command Description
1407.0806.32 6.17 E-2
MMEMory:DATA <file_name>[,<binary block data>]
MMEMory:DATA? <file_name>
This command writes the block data <binary block data> to the file identified by <file_name>. The
IEC/IEEE-bus terminator should be set to EOI in order to ensure correct data transfer.
The associated query command transfers the specified file from the R&S Signal Generator to the
IEC/IEEE bus and then on to the control computer. It is important to ensure that the intermediate
memory on the control computer is large enough to take the file. In this case, the setting for the
IEC/IEEE-bus terminator is irrelevant.
This command can be used to read/transfer stored instrument settings directly from/to the
instrument.
The binary data block has the following structure: #234<block_data>
# always comes first in the binary block
<number> indicates how many digits the subsequent length entry has (2 in example)
<number> indicates the number of subsequent bytes (34 in example)
<binary block data> binary block data for the specified length
Example:
MMEM:DATA 'TEST1.savrcl',#3767<binary data>
'writes the block data to the file 'test1.savrcl'.
MMEM:DATA? 'TEST1.SAVRCL'
'sends the data of the file 'Test1.savrcl' from the R&S Signal Generator
to the control computer in the form of a binary block.

MMEMory:DCATalog? <path>
This command reads out the subdirectories of the specified directory. If no directory is specified, the
default directory selected with the MMEM:CDIR command is read out. The directories are output in a
list (the list entries are separated by commas).
The command is a query command and therefore has no *RST value.
Example:
MMEM:DCAT?
'reads out the subdirectories of the current directory.
Response: 'test', 'wave', 'digital'
'the subdirectories 'test', 'wave' and 'digital' exist in the current directory.
*RST value Resolution Options SCPI
- - Device-specific
MMEMory:DCATalog:LENGth? <path>
This command reads out the number of subdirectories in the specified directory. If no directory is
specified, the directory selected with the MMEM:CDIR command is read out.
Example:
MMEM:DCAT:LENG
'reads out the number of subdirectories in the current directory.
Response: 3
'there are 3 subdirectories in the current directory.
