5.7.4.8 How to Create a Data List Using Tag File Format
The R&S SMW provides the following ways to create a data list file:
●
To use the dedicated "Data List Editor" and create a file with extension *.dm_iqd,
see "To create data lists manually" on page 287.
●
To use the tag-oriented format and create a data list file, see "To create a data list
file using tag file format" on page 326.
●
To use SCPI commands and create a file in binary format, see "To create a data list
in binary format" on page 326.
To create a data list file using tag file format
► Use a hex data editor and create the mandatory tags: {TYPE}, {DATA
BITLENGTH} and {DATA LIST}
Consider the tag syntax and rules.
The following is an example of the data list file content. The tags are separated by
line breaks for better reading. The text in brackets is short explanation.
For details, see the tag description:
●
TYPE
●
{DATA BITLENGTH}
●
{DATA LIST-Length}
{TYPE:SMU-DL}{COPYRIGHT:Rohde&Schwarz}
{DATE:201-06-11;15:00:09}
{DATA BITLENGTH: 8}
{DATA LIST-2: #d0d1...d7}
(1 byte containing 8 data bits d0 to d7 in binary format, where d0 is the MSB)

To create a data list in binary format
► Use the commands BB:DM:DLISt:..., see "Handling List Files" on page 1012.
:MMEM:CDIRectory "/var/user"
// Create a new data list file.
:SOURce1:BB:DM:DLISt:SELect "dl_new"
