Data List Management…
Calls the "Data List Management" menu. This menu is used to create and edit a data
list.
All data lists are stored as files with the predefined file extension
*.dm_iqd
. The file
name and the directory are user-definable.
The data lists must be selected as a data source from the submenus under the individ-
ual function, e.g. in the channel table of the cells.
Note:
All data lists are generated and edited by the
SOURce:BB:DM
subsystem com-
mands. Files containing data lists usually end with
*.dm_iqd
. The data lists are
selected as a data source for a specific function in the individual subsystems of the dig-
ital standard.
Remote command:
[:SOURce<hw>]:BB:WLAN:PSDU:DATA
Scrambler
(OFDM)
Activates/deactivates the scrambler and selects the mode of determining the initializa-
tion value.
"OFF"
The scrambler is deactivated.
"Random"
The scrambler is activated.
The initialization value of the scrambler is selected at random. Each
frame has a different random initialization value. The value is also dif-
ferent, if successive recalculations are applied. The recalculations
have the same setting parameters so that different signals are gener-
ated for each calculation.
"User"
The scrambler is activated.
The initialization value of the scrambler is set to a fixed value that is
entered at "Scrambler Init (hex)". This value is then identical in each
generated frame.
Remote command:
[:SOURce<hw>]:BB:WLAN:SCRambler:MODE
Scrambler (CCK,PBCC)
Activates or deactivates the scrambler. Some tests require a test signal without scram-
bling (e.g. for the RF carrier suppression measurement).
"OFF"
The scrambler is deactivated.
"ON"
The scrambler is activated.
"Preamble
Only"
The scrambler is activated.
Only the preamble is scrambled.
