● Example "How to assign and activate a data list" on page 982
To create a data list in binary format
► Use the commands BB:DM:DLISt:..., see "Handling List Files" on page 913.
MMEM:CDIRectory "/var/user"
// create a new data list file
SOURce1:BB:DM:DLISt:SELect "dl_new"
// append data to the data list and query the content
:FORMat ASCii
SOURce1:BB:DM:DLISt:DATA:APPend 0,1,1,1,0,1,0,1
SOURce1:BB:DM:DLISt:DATA?
// Response: 0,1,1,1,0,1,0,1
See also Example "How to assign and activate a data list" on page 982.
Example: How to assign and activate a data list
Note: Irrespectively on the way they are created, generated data lists are not automati-
cally used.
We assume, that a data list dl.dm_iqd is created and stored in the direc-
tory /var/user/.
The following example shows how to enable the R&S SMW to use this data list as data
source for the custom digital modulation.
MMEM:CDIRectory "/var/user"
SOURce1:BB:DM:DLISt:CATalog?
// Response: dl
SOURce1:BB:DM:DLISt:SELect "dl"
Editing Waveform Files, Data and Control Lists
You can edit the internally and externally crated waveform files, data and control lists.
The waveform, data and control lists files contain binary and ASCII data.
Consider the following rules while editing files with binary data.
Rules for editing binary data (waveforms, data and control lists)
●
Use hex data editor
Always use a hex data editor to edit files containing binary data.
Editing of binary data file with a text editor, even if you only change the ASCII part
of the file, corrupts the file.
●
Adapt the length information in the {EMPTYTAG}
If you change the content of a waveform file, change also the
{EMPTYTAG-Length} value.
For example, if you add a tag or add bytes to an existing tag, reduce the length
information by the number of newly introduced bytes.
